A character has an Incompatible Orientation when they are coveted by someone who can never have them, because they just don't swing that way. They can be any character who has an incompatible sexual orientation to their admirer—a straight person with a same-gender admirer, a gay person with an opposite gender admirer, or an asexual person with an admirer of any gender.
To meet the requirements of this trope the relationship must be stated as hopeless or impossible in-universe (by a character or through Word of God) at some point in time. This means that Incompatible Orientation doesn't have to be a permanent state of being, and attempts may be made within the plot to "fix" it somehow.
In a lot of works, especially manga and anime, this is often done mostly for amusement purposes, by turning the person in love into a Hopeless Suitor or even a Butt-Monkey. Lesbians are particularly prone to receive this treatment, although others are not exempt from it.
Can be the result of Even the Guys Want Him or Even the Girls Want Her. The admirer may or may not be a Fag Hag or Hopeless Suitor. May overlap with All Love Is Unrequited and Gayngst. The reason why Sorry, I'm Gay is supposed to work. Of course, some characters can simply resort to Jumping the Gender Barrier or perhaps, if they're desperate enough, resort to Genderbending.
Compare to Settled for Gay, where they may have incompatible orientations, but they decided they probably wouldn't find a suitable suitor anyways. Compare also Last Het Romance, where the incompatibility causes a character to discover they're gay and break off the relationship. See also All the Good Men Are Gay. If a character informs someone about an Incompatible Orientation, it's either Sorry, I'm Gay or Dude, She's a Lesbian.
- Kou from Aoi Hana has it tough, since Kyouko, the girl he is engaged to, is lesbian — at least judging by her crush on Yasuko.
- Bakemonogatari: Suruga is in love with Hitagi who is straight and dating Koyomi.
- Jessie from Battle Athletes is completely straight. That doesn't stop her from attracting a one-episode female Stalker with a Crush.
- Bokura no Hentai:
- This is the source of Tamura's troubles. He falls for a straight classmate and that's why he begins crossdressing. The problem is his crush is homophobic and only uses him for sex. He isn't interested in a romantic relationship and is abusive towards Tamura. He eventually expresses disinterest in sex with Tamura once his voice begins deepening and he grows taller. By then Tamura has become fed up with him and they stop talking soon afterwards.
- Mai is attracted to Marika however Marika only likes boys.
- Akane develops feelings for Tamura however he is gay and in love with her best friend Marika.
- Cardcaptor Sakura:
- Sakura had a crush on Yukito at the beginning of the series, but he's in love with Sakura's brother Touya. He explains this to her this in the gentlest way he can; Sakura, who by that point is developing feelings for Syaoran (who, hilariously, also had a bit of a crush on Yukito), immediately gives in and even tells him that she'll be his wing-woman if needed.
- Sakura's best friend Tomoyo is crushing on her, but Sakura is in love with Syaoran. Even if she wasn't, she simply never caught on to Tomoyo's feelings and she wasn't exactly eager to reveal them anyway.
- Kuroko from A Certain Scientific Railgun has a major crush on her onee-sama Mikoto, who in turn has a huge crush on Touma, the main character of A Certain Magical Index, a guy.
- In Dangan Ronpa 3, Juzo Sakakura is secretly in love with his best friend and classmate Kyosuke Munakata, who is in a relationship with the guy's other friend and classmate Chisa Yukizome. When Junko Enoshima discovers this, she threatens to out him to the friend he loves unless he tells him that she is innocent. Sakakura is unable to let his secret be revealed, and he does what she said, causing him much self-loathing.
- Misa Amane of Death Note is in love with Villain Protagonist Light Yagami despite the fact that Word of God reveals he's "incapable of loving women." The same applies to the other woman vying for his affection, Kiyomi Takada.
- Kudo from Doki Doki School Hours has a major crush on Suetake, who in turn is totally oblivious regarding his feelings. Of course, this could also be due to the fact hat Suetake is a complete dolt. And Kitagawa definitely has a thing for her teacher Mika, who doesn't appear to swing that way at all.
- In The Gentlemen's Alliance, student council president Shizumasa aka Takanari has so many women chasing after him that he has Maguri, another male member of the Student Council, pretend to be his lover. The problem with this arrangement? Maguri actually does have feelings for him, and has to sit by and watch while he chases the main heroine instead.
- Girls Bravo:
- Haiyore! Nyarko-san
- An example of Incompatible EVERYTHING with Cuuko (Cthugha). She's got a lesbian crush on Nyarko, who is both straight and head-over-heels in love with Mahiro Yasaka. On top of that, Nyarlathotepians and Cthuguhans are mortal enemies, so their very natures are in conflict, and the idea of two even being friends is unheard of; Nyarko tells Mahiro that Cuuko's family would be utterly shamed if news of the crush got out. Of course, Cuuko's inconsistent on this; one arc has Mahiro and Nyarko swap bodies, and Cuuko immediately puts the moves on Mahiro-in-Nyarko, saying "Just Nyarko's body is fine."
- Cuuko eventually develops feelings for Mahiro and starts advocating the threesome solution; while Mahiro's straight, he still rejects the idea because Cuuko's proposal includes "I bear Nyarko's child, the Boy bears mine". And finally, Cuuko has a cousin called Cuune who is so in love with her that she asked her to make a Childhood Marriage Promise with her (Cuuko was too young to understand the implication of it). Mahiro had to play The Beard to Cuuko so that Cuune would give up on Cuuko and so that Cuuko's love for Nyarko wouldn't come out and ruin everything.
- Of course, part of the story's whole hook is this. Mahiro is attracted to Nyarko as a person, but is put off by the knowledge that she's Nyarlathotep, the malign god of chaos and madness from the Cthulhu Mythos. The fact that she could shatter his sanity just by changing forms, and that she might be lying about being in love with him just to screw with him, are deal-breakers in Mahiro's eyes, but over time he grows to accept her honesty and his true feelings for her.
- Hasta is also in love with Mahiro, and he's both a Humanoid Abomination (Hastur) and a guy. Ironically, in general terms Mahiro gets along with him the best out of the alien trio because he acts more like a needy little brother and less like a Clingy Jealous Girl.
- Almost aggravatingly so in Hana-Kimi with Nakao and his blatant crush on the womanizing Minami Nanba, whom Nakao still believes he has a chance with.
- In Hayate the Combat Butler, Luca confesses to Hayate that if he were a guy, she'd have fallen for him. She thinks he's a girl because she's only met him while he was crossdressed, so she doesn't know that Hayate is actually a guy, and that she actually did confess to him because of it.
- Even before the confession he didn't want to let her know he's actually a guy.
- Both Miki and Ayumu have expressed romantic interest in Hinagiku as well, and decided to take a backseat to things, since Hinagiku is smitten with male Hayate. Ayumu has expressed interest in Hayate as well, allowing her to possibly supercede the limits of this trope without changing any orientations.
- In High School DXD, Issei Hyoudou has a few boys in his Unwanted Harem. While he cares about them as brothers and protects them from harm, Issei is 100% straight and finds Ho Yay moments to be annoying and embarrassing.
- Midori from I'll Bring You Mille-Feuille! really wants a husband despite being a lesbian. Her friend tells her it's an useless idea however Midori doesn't acknowledge her, until she tries to have sex with a man but is too repulsed to.
- I'm Gonna Be an Angel!:
- Sara develops a big crush on Mikael in the second season but it never goes anywhere because first, Mikael has only eyes for anything related to angels and second, he's already in love with his male teacher, Raphael— even if he has problems admitting the fact to himself.
- Similarly, Natsumi has some questionable feelings towards her deceased older brother Fuyuki over whom she obsesses throughout the whole series, but again, it never goes anywhere because first, Fuyuki is well, dead and he turned into an angel Raphael and second he's in love with his male student, Mikael.
- Kämpfer: This is the primary romantic woe of Senou Natsuru: His crush, Sakura Kaede, turns out to be a lesbian. This became more complicated when she falls for his female self.
- Happens twice in Karakuridouji Ultimo. Akitsu has a crush on Rune, who has a crush on his best friend Yamato, who has a crush on a girl named Sayama. We should point out that Rune does not take it very well. At all.
- In Katekyō Hitman Reborn! Lussuria has a creepy love for Ryohei to the EXTREME even though he is straight (and one of the few to be obviously married in the future).
- Possibly the case in Kyo Kara Maoh!. Wolfram is head-over-heels for Yuuri. Yuuri wishes people would stop assuming he feels the same. Alternatively, the rest of the world could be right, and Yuuri could be living in a Transparent Closet.
- Parodied to hell and back in the aptly named Jump SQ one-shot "I'm the protagonist of a Harem manga, but I'm gay so my life is a living hell."
- Magic User's Club takes the cake for having multiple cases in the same Love Dodecahedron. Aburatsubo, the bishonen gay vice-president is crushing on Takeo, the straight club president (who lusts for Cute Witch Sae, who is too shy to express her feelings for Takeo). Meanwhile Nanaka (another Cute Witch and club member) has a crush on Aburatsubo, which he can't return either. They have a heartwarming moment when she confesses and he turns her down... but admits that he knows fully well how she feels, unable to have the one you love.
- Masato from Manga no Tsukurikata is in love with his childhood friend Morishita, who in turn is in love with his sister.
- Toyed around with endlessly in Maria†Holic. The main character goes to an all-female school to meet girls, and basically falls in love with every girl she meets.
- Sachiko from Maria-sama ga Miteru is in an Arranged Marriage with her cousin, who is actually gay. Sachiko Does Not Like Men and is really into Yumi, but has mentioned she liked Kashiwagi when she was younger.

- Ladies' man Sanji is wanted by the entire population of the gay island Kamabakka Kingdom.
- Boa Hancock could have any man in the world who was even slightly attracted to women, plus all the girls from her kingdom... but she ends up falling for Luffy, who is completely' Oblivious to Love and simply not interested in romance.
- Outlaw Star:
- Camp Gay Arms Dealer Fred Luo is in love with straight Handsome Lech Gene Starwind, but neither of them seems to Gayngst about it. Gene uses Fred's crush to score better deals on parts and weapons, and Fred uses Gene's desperation for said parts as a bargaining chip in his less legitimate business endeavors.
- Lampshaded when Fred tells Gene that, in exchange for supplies, he 'owes him a favor'. Gene doesn't miss a beat before responding "I'm not going to sleep with you Fred."
- Fred Luo's also on the receiving end of this trope, as his parents refuse to accept he's gay and so have an Arranged Marriage for him to a woman named Reiko Ando, who genuinely does love Fred even as he finds her sexually repugnant.
- Furui of Poor Poor Lips, despite his initial dislike towards her, ends up having a crush on Ren. This causes him no small amount of angst since one of the causes for his initial dislike is his discomfort around the fact that Ren is an out of the closet lesbian.
- In Queen's Blade Grimoire, when Alicia and Tiina share a dance, Tiina admits she has a crush on Alicia and wishes Alicia were a boy. Alicia quickly says she doesn't swing that way.
- Saber Marionette J makes a running gag of the attraction the flamingly gay rich boy Hanigata has for the poor, industrious (and fundamentally straight) Otaru.
- In Sasameki Koto Masaki Akemiya has an adorable, albeit unfortunate, crush on his girl-loving classmate Sumika Murasame. He develops Wholesome Crossdresser traits due to his affections.
- Sanae Ebato of Scum's Wish is pursued by her cousin Atsuya, despite outright stating she has no interest in men, and being generally creeped out by his attempts. Atsuya, for his part, seems to be aiming for her to concede If It's You, It's Okay.
- Seraph of the End: Mitsuba, Shinoa and another school girl are shown to have feelings for Yuu, while Akane is a Hopeless Suitor for Mika as well. However, Mika and Yuu are all but stated to have feelings for each other and instead focus more attention on the other.
- Shinya is hinted to have feelings for Guren, who is well known to have a romantic and sexual relationship with Shinoa's big sister Mahiru.
- Gouriki develops a crush on Tanukichi after seeing him crossdress as a girl, to protect Anna. But since the Japanese government has prohibited even basic Sex Ed from being taught at schools for the last 16 years, Gouriki fails to recognize his own feelings for what they are, nor does he realize that Tanukichi is straight.
- On the girls side, Kosuri develops a canonical girl-crush on Ayame by episode 12, when she openly gropes her while they're in the furo. Ayame is visibly shown to be put-off by her advances and protests the entire time.
- In Taisho Baseball Girls, Tomoe has a thing for Koume, who in turn seems to be rather content with her arranged fiancé.
- In Tamako Market, Midori has a crush on her female friend, the main character, Tamako. There's an episode where she gets jealous of Tamako's chemistry with her male childhood friend, Mochizou, and tries to sabotage their relationship for her own sake. In the end, she reluctantly accepts that Tamako isn't homosexual and stops getting between Tamako and Mochizou (who go on to be an Official Couple).
- Tooru Mutsuki in Tokyo Ghoul is a trans male with feelings for Kaneki, a cis male, who is in love with Touka.
- Vampire Game: Laphiji is in love with Seiliez, his Not Blood Sibling. Unfortunately for him Seiliez is shown to be straight considering his crush on Ishtar. However this can also be subverted for it is hinted later on that Laphiji and Seiliez do begin a sexual relationship... albeit one that is likely to not last long.
- Wandering Son:
- Makoto has fallen for several boys (and adult men), however the current object of her affections is her (ignorant and immature) friend who is Oblivious to Love.
- One of the reasons Chiba's crush on Nitori is unrequited, aside from her lack of romantic feelings for Chiba, is because she loves her due to seeing her as a boy. Even though Chiba appeared supportive of Nitori's interest in wearing women's clothing at first, it's later revealed to be because she saw it as a "girly phase" and that Nitori was just a boy who happened to like crossdressing. This of course is not the case. This is also the reason she's so jealous of Takatsuki whom Nitori has feelings for - because she doesn't understand why Nitori could choose him over her even though they are both female, when Takatsuki is similarly a transgender.
- In WORKING!!, Jun is having a hard time with his feelings for his colleague Yachiyo, who in turn is in love with Kyouko, her female boss at the family restaurant they work at. Questionable - although Yachiyo is utterly devoted to Kyouko and would almost certainly be willing. There is no direct evidence that they have ever been lovers or that either have ever had lesbian sex with anyone.
- In Yurika's Campus Life, this is played to almost ridiculous levels. The titular character considers herself straight, and while men do find her beautiful, they are unable to be attracted to her sexually. Other women on the other hand, even those that believed themselves straight find her extremely sexually attractive.
- Tetsuo is a straight trans man. He's noted that it is hard being romantic as women get turned off when they learn his biological sex. His Only Friend Amano has a crush on him, originally because he was attracted to him as a boyish woman, but later he began seeing him as male and liking him as such. It turns out Tetsuo is actually bisexual, though he simply didn't acknowledge it until meeting Amano, and they end up the Official Couple.
- Tetsuo's mother once tried to marry him off to a man. Tetsuo refused because he didn't like men, though stated that he wanted to be like brothers with his fiancee. When he told his fiancee of his dislike of being female and his lack of interest in men, he ended up confused. When they meet several years later, he still considers Tetsuo his fiance... but he has mental problems and doesn't even recognize that he is horribly disfigured, nevermind that Tetsuo is living as a man. In the end, the guy passes away and as said above, Tetsuo and Amano stay together.
- Batman villain Two-Face has spent the better part of a decade being obsessed with Renee Montoya despite her lesbianism. In fact, it was one of his attempts to woo her that ended up outing her in the first place.
- Renee Montoya, by that time the new Question, was involved in another example, this time on the other side. Both in Birds of Prey and in the Question back-up feature in Detective Comics, Question teamed up repeatedly with Huntress, and it became quite clear that she was interested in Huntress (Helena Bertinelli) romantically. The storyline never had time to develop very far before DC's "New 52" reboot, but Huntress had always been portrayed as straight, and was not even aware that Question was gay, at one point asking if she and the previous Question, Vic Sage, had been lovers.
- In Batman Incorporated, the Hood tries to hit on Batwoman while they're Working the Same Case, unaware that she's a lesbian.
- Lipstick Lesbian Karolina spent much of the first two volumes pining for her best friend, Nico, who was a little shocked when K finally tried to kiss her. After beginning a relationship with shapeshifting Skrull Xavin, who takes on the form of a human girl, Karolina loses romantic interest in Nico. Then again, this hasn't stopped them having Ship Tease moments since.
- The straight male Chase was clearly interested in Karolina in the early issues. He and Nico eventually got paired off with, respectively, Gertrude and Alex. Neither pairing ended well.
- Northstar once had a crush on Iceman. It didn't take him long to realize it would never happen, since in his own words "He's straight. End of story." (It was only introduced to squash fan speculation that Iceman might be gay.) Ironically, that fan speculation turned out to be dead on, since Iceman was outed as gay a few years later.
- Subverted in Exiles: Morph had a crush on teammate Sunfire without realizing she was a lesbian. When she made The Reveal, he accepted it wholeheartedly and continued to act as a brother figure to her, even supporting her relationship with Spider-Woman. (Well, accepted it wholeheartedly after giving the "Hey, I'm a shapeshifter, I can do lesbian" line a shot...)
- In Buffy the Vampire Slayer Season 8 comics female Slayer Satsu falls in love with Buffy and they have sex at least twice. But Kennedy, another lesbian Slayer, dissuades Satsu from pursuing a relationship with her. Why? Because she claims that ultimately, Buffy is straight.
- Molly von Richtofen from The Punisher dashes Detective Soaps hopes when she reveals she's a lesbian. It also turns out that the whole reason she's such a pariah at the NYPD is because she turned down the commissioner's advances while unaware that she was within range of a microphone.
- Blackhawk': When Lady Blackhawk joined the Birds of Prey, she began nursing a crush on Creote, the muscular, deadly, Russian ex-special forces soldier who is the partner of Savant, the not-quite-irredeemable villain that Oracle is trying to rehabilitate into a good guy. Everybody knows that Creote is in love with Savant, except for Savant himself, but nobody quite gets around to letting Zinda in on this. When she finds out she is somewhat surprised.
- Tom Pearce never stood a chance with the object of his crush in Camelot 3000. Of course, it was further complicated by the Gender Bender nature of reincarnation.
- In Supergirl story arc Crucible, Maxima (lesbian) has a crush on Supergirl (straight). She goes as far as to confess her feelings because she needs to get it off her chest, but she's quite aware her love is and will always be unrequited.
- At one point in Superman comics, Dan Turpin of the Metropolis Special Crimes Unit had a crush on his boss, Maggie Sawyer, even going as far as to propose to her. She explained the situation to him (off-panel).
- Avengers Arena has Cullen Bloodstone in love with his straight best friend Aiden/Anachronism, but Aiden was too pre-occupied with vampy Atlantean Nara.
- When Kevin was introduced into Archie Comics Veronica fell for him. Kevin is gay and has a boyfriend.
- And then in the 2015 reboot comics, we have Sabrina falling for Jughead and even getting a date with him (despite his reluctance). It fails miserably, however, as he is asexual and aromantic. There's also January Jones in an earier comic, a future descendant of Archie come back in time in an imagine spot - she tries to kiss Jughead in thanks, but he pushes her off, though here he merely says that he's 'not into kissing girl Archies' which may have just been easier than trying to explain everything.
- Played with in Fearless Defenders. Annabelle Riggs kisses Valkyrie, but Valkyrie doesn't seem to reciprocate. It initially seems like Valkyrie is giving Annabelle the cold shoulder because she's a lesbian, but it turns out that it's mostly because after thousands of years of being kissed, she simply doesn't view it as a significant or meaningful gesture. She even clarifies that she's been kissed by plenty of men and women throughout her lifetime.
- Discussed in Circles. Paulie loves Mrs. Nussbaum as a dear friend and he comments, "Why, if I were straight..."
- In Robyn Hood, Marian initially has a crush on the solidly heterosexual Robyn.
- Lady Death: Wargoth has nurtured romantic feelings for his longtime companion Satasha, despite him being aware of her orientation.
- Red Ears: The punchline to a comic where two men and a woman are sitting in a train cabin and the woman starts to agressively hit on one of the guys, who flatly ignores her advances. After she angrily storms off, the other guy asks him how he could possibly resist and notes that the woman turned him on so much that he's ready to jump a fly. The first guy starts mimicking buzzing.
- In The Darkness, Jackie Estacato's brief sidekick Wenders is attracted to him and even offers his body so Jackie can get around his Can't Have Sex, Ever problem (Jackie will die if he gets someone pregnant and they give birth, but Wenders is a man). Jackie is absolutely disgusted and says it's never going to happen.
- Subverted in Axis Powers Hetalia fanfic Gankona, Unnachgiebig, Unità. Germany and Japan thought Italy was this, thinking he was straight since he flirted with girls all the time. Turns out Italy is not straight, but bisexual.
- In the Mass Effect fic Another Realm, the protagonist Cieran and his friend Trena become Platonic Life-Partners largely as a result of this, as she prefers other asari.
- In the Buffy the Vampire Slayer fic Compelled, there was a subplot where Connor had a crush on Kennedy, who is both lesbian and taken. It mostly served to give him some Character Development.
- In The Knight's Consort, another Buffy the Vampire Slayer fic, Kennedy the Vampire Slayer (a lesbian) slowly falls in love with Xander (not just a crush or a strong friendship, but actual romantic-poetry-flowers-and-schmaltzy songs love). Unfortuantely, the fact that he is male (and has no interest in not being male) keeps her from being attracted to him, or wanting to actually consummate their relationship beyond a single experimental kiss.
- Evangelion 303: Jessika is lesbian and she likes Asuka. However Asuka is straight AND taken -by Shinji-, so that Jessika kept quiet. It does not help that Jessika already has a girlfriend.
- In Respawn of the Dead, the RED Spy is in love with the RED Engineer, who is both straight, and has a family back home. Needless to say the Engineer rejects him (not helped along by the many atrocious acts that Spy commits over the course of the story), and the Spy ends up killing himself.
- In the Katawa Shoujo fanfic From Shizune's Perspective, which was written prior to the game's release, Shizune is bisexual and Misha is heterosexual, resulting in Misha rejecting Shizune's confession. This becomes Harsher in Hindsight when you consider their backstory in the final game where Shizune is the one who rejects Misha.
- In Fallout: Equestria Lilpip grows up with a crush on Velvet Remedy, who is straight. They later become best friends and Velvet goes so far as to become something of a motherly figure to her. Notable in that it's Lilpip's feelings for Velvet that compel her to leave the Stable when Velvet runs away. So this trope actually sets off the plot! (Not that kind, get your mind out of the gutter!)
- The Conversion Bureau: Not Alone has Andrew (a male human) and Ice Breaker (a male pony). Andrew admits that he's developed a crush on Ice Breaker (well aware of the incredible likelihood of this trope being in force). It is, and they remain Just Friends.
- Dragon Ball Abridged's Dende, who comes from an race with No Biological Sex, finds himself smitten by Bulma's breasts. Later, we find he has something of a crush on Gohan, as the two had been friends for a while. After a few months of living together, he confesses his love, to Gohan's confusion. Poor guy...
- In, surprisingly, a Lord of the Rings background-era fanfiction, OC Andrahar is in love with his master/best friend, Imrahil. Imrahil is very straight, however, and if this wasn't already made clear by his conspicuous tendency to frequent brothels, he offers to sleep with Andrahar "to see if he is a man for men". The results are definitive, and disappointing for Andrahar. Later fics by the same author imply that Andrahar never falls out of love with Imrahil, but they remain lifelong best friends in spite of it.
- In You Got HaruhiRolled!, Kyouko has a MAJOR lesbian crush on Sasaki, who will have none of it. The only person Sasaki feels attraction towards is herself. Kyouko is completely oblivious to this.
- In This Nearly Was Mine, Frederic Horshoepin has a massive crush on his bandmate Octavia. Unfortunately for him, this universe has the VinylTavia ship in full play, so he's stuck watching the love of his life making out with the DJ mare.
- Reading Rainbowverse has Big Mac's crush on Twilight, who admits she doesn't see stallions that way.
- The Thor fanfic 5 People Who Thought Loki Was Gay and One Who Knew Better has Thor and Jane's relationship end this way, as Thor finally comes to terms with his sexuality, something he has struggled with for the entire story (which spans centuries).
- In The Dashverse, Cloud Kicker eventually confesses to Twilight that she actually is in love with Rainbow Dash. Unfortunately for her, Dash is not only straight, but completely oblivious to her feelings, as she just assumes its part of Cloud Kicker's usual personality.
- Some fans of the Picard/Q pairing from Star Trek have pointed out the implausibility of a stout heterosexual man like Captain Picard (with several noted love interests in canon) changing his preferences by pursuing a relationship with Q's male form. As an Energy Being Q has no mortal body, so any form he assumes is more like a costume than anything else, and that "costume" could just as easily appear to be female as it does male; this is something that Q even lampshades in canon.
- In Fire Emblem Awakening fanfic Pretender Robin is love with Chrom, but unfortunately who is straight and gets married to Sumia early in the story.
- In Despair's Last Resort, Kazumi is in love with Shizuka, who is stated to be straight and was possibly in love with someone during the year at Hope's Peak. Kazumi makes it clear though that she won't chase after her, though Shizuka's execution is not handled well.
- In Angel Of The Bat Cassandra has unrequited feelings for best friend Stephanie Brown, who is both straight and in a relationship. Despite her desires, Cassandra only admits it because she is tired of carrying it and doesn't want to hurt their relationship.
- Applejacks Love; Applejack has a crush on Rainbow Dash, and eventually confesses her love. Rainbow is straight, hates being Mistaken for Gay, and thus takes AJ's confession badly.
- The Mysterious Case of Neelix's Lungs: Harry Kim (gay in this fic as an Actor Allusion) briefly carries a torch for Tom Paris, but late in the first season he complains to Emil Tarak that Paris isn't into men. Harry also has to rebuff advances from a female Sikarian in "Factoring Primes".
- The Elements of Friendship: Book II, Applejack confronts Twilight on the kiss she gave her in Book I, Twilight explains it was chaste and she's aromantic. Applejack admits she's kind of disappointed.
- In the Frozen fanfic Becoming Free, Freya kissed her childhood friend Greta when she mistook their bond for romantic. Greta reacted badly. She ran off, told her family, and later that day her family came and burned down Freya's house. They likely would have harmed Freya if she hadn't escaped. Greta didn't intend for them to attack Freya, and when they meet years later she is regretful.
- The Alarmaverse: Twilight Sparkle and the Case of Old Res: Resonius IV and Pitch Drop. One's heterosexual and in love with the other one who is gay.
- The driving force behind A Stallions Man, which designates a man named Barrett as the object of the affections of seven eager - and familiar - stallions,note all of whom cannot accept that his barn door doesn't swing that way (it's only a gender barrier, though; Interspecies Romance doesn't bother him and in fact he wants a marefriend). He outright tells them, but only a few acknowledge hearing it - regardless, none give up on winning his heart, certain that they can change his mind and bring out the repressed homosexual they're certain lurks underneath. How exactly Barrett ended up in this situation is uncertain as of right now, but it's possible that, in order to escape a dreary life back home, he wished to end up in the show with all the main characters fawning over him... and just failed to specify which gender he was actually into, or something else that he didn't think he had to clarify. Now he's stuck with it, with no way back. The fic also greatly exaggerates the implications of this trope, making several - if not all - of his harem's members boy-crazy to an over-the-top extent just for laughs.
- The Loud House:
- Many fans have written fanfics where Luna's female crush Sam isn't interested in girls. Given that this was a hinted at but never outright stated concern in canon, it's no surprise fans have been intrigued by it. How much angst this causes depends on the work in question but Luna's always disappointed when Sam turns her down.
- Less popular but still a thing is that Clyde's crush on Lori is being used to cover up feelings for the very straight Lincoln, whether consciously on Clyde's part or not. How much angst there is depends on the work in question but there's always initially awkwardness between the boys and Lori may even be drawn into it considering how weird it would be to have someone's crush on you derive from feelings for your little brother.
- Dungeon Keeper Ami: One of Drunk Ami's fears about her relationship with her crush, as said in her thoughts from Beryl's Plan:
A horrible thought almost made her gasp out loud. Could it be that he was gay? She needed another drink! A moment later, she settled back against him, her thirst slaked. This required some careful observation.
- Principal Celestia Hunts the Undead: Applejack crushes on Sunset at the beginning. Sunset, who is straight, gently turns her down.
- Man Of Dreams has this within a Love Triangle: Mito (straight) with Hashirama (gay). Both of them with Madara (asexual).
Perhaps it was because on some level Hashirama knew who Mito was really interested in marrying; and on that same level, Hashirama acknowledge it was the same person he was interested in.
- In Batman: Bad Blood, Dick Grayson mentions that he used to have a crush on Kate Kane when they were kids, until he found out she was a lesbian.

- In Blackbird, Randy is in love with a boy who is straight and has a girlfriend.
- Bridget Jones in the film version of the sequel feared her boyfriend Mark was cheating on her with his assistant Rebecca Gillies until it turned out that Rebecca was sharing her colleague's affections for Bridget.
- In But I'm a Cheerleader, the plot not only starts with this trope but revolves around it.

- Kissing Jessica Stein played around with this trope - while technically subverting it, as the straight eponymous heroine falls for another woman - the bisexual Helen, they don't make it in the long run, due to lack of sexual chemistry.

- In Doctrine of Labyrinths, especially at the beginning of the second book, Felix (gay man) is attracted to Mildmay (straight man).

- Robin Hobb's Realm of the Elderlings: Comes into play in the Farseer and particularly Tawny Man trilogies between hero Fitz, who is quite straight, and his best friend the Fool, who is quite in love with Fitz. The Fool is quite open about his feelings, though he denies that there's anything sexual implicit in love; the situation serves, however, as a major source of discomfort for Fitz once rumors start flying about their relationship.

- Discussed in Simon vs. The Homo Sapiens Agenda. While Simon never comes across this directly (he states he has a policy for not falling for straight guys), he and Blue bond over the fact that being closeted in a school where there are no other openly gay guys mean hell for any attempt at dating.

- In the Zeroes series, Scam spends six months pining after Mob and trying to work up the courage to confess his feelings to her, unaware that she's a lesbian.

- In Twig there is a deadly serious and heartbreaking example between Sylvester and his best friend the first Jamie. The latter lets the former find out about his feelings shortly after encouraging a girl who also has a (reciprocated, though neither of them fully recognise it yet) crush on him to be more open in pursuing him. The combination of shock and resentment that the friendship that was his absolute rock in a truly hideous Crapsack World has been destabilised causes him to react very insensitively. After a night of soul-searching, Sy decides to greet Jamie with a sincere smile because their friendship is more important to him than anything else, only to discover that Jamie's inevitable Loss of Identity was accelerated by his pain the night before, and his friend's mind has been replaced with a blank slate.
- The same problem rears its head between Sy and the second Jamie, but this one is handled by this Jamie pointing out that, as a hermaphroditic experiment, Jamie was only ever a boy because the doctors decided the gender, and Jamie feels little enough attachment to being male that it would be very easy to be female. Jamie becomes Jessie (with Sy's extremely malleable brain letting him switch his own perceptions of his friend with little effort) and a relationship becomes possible, as well as allowing Sy to stop seeing the ghost of the first Jamie in the second one.
- In 'Allo 'Allo!, the very campy Gruber is hopelessly infatuated with the very straight Rene, who is frequently discomforted by the fact that Gruber "fancies" him. (Ironically, Gorden Kaye, the actor who played Rene, is in real life a very content and "out" gay man.) The series finale showed that Gruber had married Helga after the war and had many children with her, perhaps making this a further case of Incompatible Orientation from her side.
- The reality show Boy Meets Boy had a gay male bachelor choose a mate among several guys, but unknown to him, half the guys were straight and planted by the show to see if he'd fall for one. One of the straight guys, however, had a change of heart when he grew to like the bachelor as a person. He eliminated himself because he wanted him to have a real chance to find love.

- Buffy the Vampire Slayer:
- One episode features a high school guy whose magic jacket makes any girl fall in love with him if they see him wearing it. Willow, a lesbian, is one of the many girls who fall under its spell. Hilarity Ensues.
Buffy: Willow, you're a gay woman! And he... isn't!
Willow: This isn't about his physical presence! It's about his heart.
Anya: His physical presence has a penis!
Willow: I can work around it!
- Willow's case overall in the series tends to fall under No Bisexuals: now that we've established her as lesbian, we just couldn't have her be interested in a man, despite her previous physical relationships with Oz and Xander.
- In the same episode Willow attempts to get around this trope by using a spell to change the man into a woman. Fortunately for him Xander and Spike stop her from completing the spell.
- Buffy is this with Satsu. Even though Buffy is flattered, and sleeps with her (twice!), she is quite adamant that she is not a lesbian and they can't be together.

- Played for comedy in an episode of The Catherine Tate Show where a lesbian nurse falls in love with (the very man-eating) Bernie.
- Fiona from Degrassi has come out of the closet, in the process revealing she had a thing for her best friend Holly J.

In another episode, Fiona's locker is near the hockey team's lockers, and Dallas hits on her. She then says that she and her girlfriend Imogen are lesbians, but he doesn't believe her, since they don't kiss.
- Doctor Who:
- In "Rose", the Ninth Doctor flips through one of Jackie Tyler's gossip mags and exclaims, "That won't last! He's gay and she's an alien!"
- Played with and ultimately averted in a flashback scene from "Let's Kill Hitler"; when Mel questions why Amy and Rory haven't gotten together yet, Amy answers, "I'd love to, he's gorgeous, he's my favorite guy, but he's, well, gay." Rory then informs him that he is not, and after awhile Amy realizes that there is one girl Rory has eyes for; her!
- "Knock Knock": Paul, one of Bill's new housemates, attempts to flirt with her a few times. Once she catches on, she informs him she's only interested in girls.
- Happens to Bill again when a Roman soldier flirts with her in "The Eaters of Light". She nervously explains that she's only attracted to women, most likely expecting the people in this time to be homophobic. She instead gets mocked as "old-fashioned" for only being attracted to one gender. Not That There's Anything Wrong with That, it's just that normal people like both.
- During the third season of ER Carter develops an attraction to fellow intern Maggie Doyle. All signs appear to be heading for them to end up in bed together. . .until she runs and hides behind him to avoid being seen by her ex-girlfriend, thus revealing that she's a lesbian.

When everything unravels, Frasier is most incensed that no one was attracted to him.
- Rachel reveals that she kissed one of her sorority sisters, which Phoebe doesn't believe. Rachel takes Phoebe to dinner with the sorority sister, who insists she has no idea what Rachel is talking about. After dinner, the sorority sister reveals that after that kiss, she started feeling differently about Rachel and in fact pictures her face when she makes love to her husband. Rachel obviously does not return the feelings.
- In a later episode, Joey attempts to woo the hot nanny Ross and Rachel hired to look after their infant daughter, only to discover she's a lesbian. Of course, he doesn't seem to mind this turn of events.
Joey: It's like my favorite bedtime story come true: 'The Princess, the Stable Boy, and the Lesbian!'
- Ross is divorced from his lesbian ex-wife Carol but still retains feelings for her early on. After some heated arguments involving her life partner Susan and the birth of their son, Ben, they maintain a healthy friendship and share custody of Ben.

Margaery: Would you like my brother to come in and help?
- In The George Lopez Show, this is subverted in the episode "What George Doesn't Noah". Carmen brings home what seems to be the ideal boyfriend, Noah, after dating bad boy Zack. George and Benny spy on Noah and find him with another man in a movie theater. Turns out, Carmen was using Noah as a cover so that she could date Zack secretly.
- In Glee, Kurt has a crush on Finn. In one episode, Rachel points out that she will always have more of a chance with Finn than he does because of the simple fact that she is a girl.
- Mercedes also had a crush on Kurt. For reasons unfathomable, he turns her down.
- Kurt also starts making out with and dating Brittany in one episode because he feared that his father saw the heterosexual Finn as a better son. His dad is understandably confused.
- Depressingly, this also happens between Sam and Kurt. Kurt was only vaguely interested in him and more just determined to make him admit he dyes his hair. (Which he does.) This pairing seems to be 10% canon, 90% indignant fandom who are mad that Ryan Murphy changed his mind at the last minute (again) about Sam being Kurt's love interest.
- Also, Blaine and Rachel, if only for one episode. After a drunk kiss with Rachel, Blaine (who has until then believed himself to be gay) decides that maybe he's actually bisexual. They go on a date, but when they kiss again while sober, Blaine realises that he was wrong about being bisexual. Subverted, as Rachel didn't seem to actually be in love with Blaine. It seems that the fact that he can sing and is a good kisser is enough for her to decide to date him, and she's positively thrilled when he tells her that he's gay after all:
Rachel: That was amazing! I am speechless! I just had a relationship with a guy that turned out to be gay; that is song writing gold!
- Also, in one episode, after Kurt gives Rachel a pep-talk, she says that she wishes he was her boyfriend. It's mostly joking though, since they are both taken.
- Blaine also gets two of the girls from Dalton's sister school charmed by his performance of Animal and try to give him their phone numbers, asking him to call them. His response? "Sweet, but not your team."
- Blaine was also crushing on Sam for a while in season 4. It took him a while to confront his feelings and to share them with Sam. Sam turned him down gently, saying they are first and foremost best friends.
- Santana ultimately turns out to be this for Puck. He takes it well, though; by the time she's on the road to coming out, he's moved on, and in the episode where the club helps Santana dealing with her outing, he says that he knows that he "was just a phase" and is fine with it.
- As of "Sadie Hawkins", Tina believes Blaine (gay) is her soulmate despite him turning her down for obvious reasons. Blaine has a massive crush on Sam (straight) but won't act on it because he doesn't want to be a "predatory gay" and because he's "proud that a gay guy can be friends with a straight guy."
- On Happy Endings, Max's old high school girlfriend is visiting and she and Dave hit it off. Max gets very upset by this, which Dave can't understand since Max is gay and obviously won't be getting back together with her. Max, in order to make Dave jealous, grabs Alex (Dave's ex-fiance) and kisses her, but Dave doesn't care because he knows it doesn't mean anything. Then Alex, who enjoyed the kiss, spends the rest of the episode mooning after Max (while Penny tries in vain to get her to see it's hopeless).
- Season 4 of Heroes has Claire's roomate Gretchen reveal herself as a bisexual who has a crush on her. This appears to be a case of incompatible Orientation as Claire is thought to be completely straight at this point.

- The short-lived John Ritter show Hooperman featured a Running Gag involving a gay cop named Rick and a fellow officer named Mo who repeatedly hit on him despite him having no interest in women.

He spends a night as her Gay Best Friend, and promises that his next brain will be "ludicrously straight", discussing the idea of possibly digging up Wilt Chamberlain.
- In Lip Service, Ed has a hopelessly unrequited crush on his lesbian friend Tess.
- Murder in the First: Jamie Nelson is obviously attracted to a pretty female bartender, and thus visibly disappointed when she's revealed to be straight, with a boyfriend.
- Rae and Archie in My Mad Fat Diary.
- My So-Called Life: After her disastrous crush on Brian, Delia has that glorious dance scene with Rickie. By the last episode, the only one oblivious to her newfound crush is Rickie. When he tries to reciprocate, she tells him she knows he's gay (in that awkward, teenage way — "You're gay, right?")
- In The Nanny episode "The Playwright", Maggie is in love with Gracie's ballet teacher, who helped her with her make-up and does great Liza Minelli impressions. Fran is just suspicious until Maggie says something about him getting along well with his "roommate" Chuck.
- Night and Day's Fiona and Mike Brake, despite many years of marriage.
- In Once Upon a Time Mulan finally gets the guts to tell Aurora she's in love with her... and Aurora beats her to the punch by announcing she's pregnant.
- In the first season of One Day at a Time (2017), Elena briefly dates Josh, but she simply cannot get as into it as he is. This is part of what helps her realize she's a lesbian. Fortunately, Josh is extremely cool about this, and still escorts Elena at her quinces as a friend.
Elena: It was just, I realized that if I was going to be into a boy, it would be Josh. I mean, he's cute, and he's sweet, and he's such a gentleman, but I feel more when I look at a picture of Kristen Stewart than I do when I kiss him.
Penelope: No wonder you saw those Twilight movies so many times.
Elena: Definitely wasn't the quality storytelling.
- Usually averted in Orange Is the New Black, because being in prison often makes the ladies reconsider, but present from time to time.
- Poussey and Taystee may be the most compatible life partners you'd ever seen on TV, but the latter just isn't a lesbian.
- Nichols tries hitting on Fischer, but is understandably turned down; Fischer is straight and a guard. Well, Nichols is ambitious.
- Luschek suffers from the exact opposite problem concerning his crush on Nichols. She's gay and an inmate, making a romance both impossible and a crime.
- Oz: When Richie Hanlon (gay) joins Shirley Bellinger (straight) in the Death Row block, Bellinger offers to show her vagina if Hanlon shows her his penis. He points out that he's gay, but obliges anyway when she says she doesn't care either way.
Bellinger: You must have made some guy really happy.
- Following J. K. Rowling's outing of Dumbledore, Saturday Night Live did a sketch portraying McGonagall having this sort of relationship with the gay Dumbledore:
Dumbledore: Oh Minerva, if only you had a penis and balls!
- On Seinfeld, Elaine once dealt with a crush on a gay man after being his beard for a night. Unlike most examples here, she actually succeeded in getting him to switch teams... but only temporarily.
Jerry: He went back? Whaddaya mean he went back?
Elaine: He went back.
Jerry: I don't understand, you were having such a great time! The sex! The shopping!
Elaine: [sigh] Well, here's the thing: Being a woman, I really only have access to the, um... "equipment"... what, 30, 45 minutes a week? And that's on a good week! How can I be expected to have the same expertise as people who own this equipment, and have access to it 24 hours a day, their entire lives?
Jerry: You can't. That's why they lose very few players.
- Alec's feelings for Jace on Shadowhunters, since Alec is gay and Jace is straight.
- Sherlock: There's a lot of this as the titular character is basically asexual and aromantic, making him incompatible with everyone. (Heterosexual) Molly Hooper's unrequited crush pales in comparison to the hideously confusing love triangle between Sherlock, John, and Irene. Sherlock is asexual, John constantly reminds everyone that he is heterosexual, and Irene is a lesbian. Yet Irene becomes sexually fascinated with Sherlock and observes that John is in romantic love with Sherlock whether he realizes it or not (with a physical dimension - John knocks Sherlock around to fake an alibi but can't bring himself to hit Sherlock's nose or teeth to make it convincing). Sherlock has a tongue-tied sexual fixation on Irene, while also feeling romantic love with no apparent physical dimension towards John. In short: the lesbian is in love with a man, the heterosexual man is in love with the same man, and the asexual is in love with both of them.
- Several examples in Skins:
- In the second season, Maxxie, who is gay, is stalked by a girl whom everyone calls Sketch. She sabotages her way into the school musical just so that she can kiss him, convinced she can make him love her. She also follows him home, sneaks into his house, masturbates on his bed and then hides under it while he is sleeping. Now you know how she got that name. The strangest thing about Sketch is that she is aware that Maxxie's gay and somehow thinks that by dressing in masculine clothes and binding her breasts, she'll break through the Incompatible Orientation barrier. When she decides to go after his best mate Anwar (who is straight) instead, she stops binding and starts wearing more frills and make-up.
- Naomi tries to tell Emily this in the third season, but it's eventually revealed that she was just Armoured Closet Gay and has always loved Emily and only Emily.
Naomi: Me, not muff-muncher. Me, cock-cruncher.
- J.J and Emily. Emily offered to take his virginity the same day that she came out of the closet.
Emily: This is a one-time only charity event, you understand?
J.J.: Got you. Because you are gay.
Emily: Yes, I'm gay. Get on with it.
- This understanding didn't stop him from hoping for the possibility of a relationship when she asked him to the Love Ball, but it turned out that he was her beard, and she left him when Naomi showed up.
- Cook and Naomi. She tried to jump him when she was still in denial about her sexuality, but stopped after about forty seconds of mad snogging, since she realized that she didn't want to do it. In the fourth season they share a big heart-to-heart, and Naomi ends up giving him a very platonic kiss, giving us:
Cook: [beat] For f—ks sake, I'm never gonna get to bone you, am I?
Naomi: [Very matter of factly] No, I love someone.
- When new character Alex is introduced in the sixth season, Liv gets a crush on him, only for him to reveal that he's gay when she admits her feelings.
- The American remake has a very strange version of this with lesbian Tea and straight Tony. Tea sleeps with Tony as a joke, but he gets feelings for her. Yet, for some reason, she keeps sleeping with him, out of either a power trip or because she's confusing their platonic chemistry with sexual chemistry, depending on which interview you read. It ended up as a Relationship Writing Fumble since Tony and Tea were more believable together than Tea with her actual girlfriend and love interest, Betty. And yet, the show kept insisting that she was a complete, 100% lesbian with no interest in Tony.
- An episode of The Thin Blue Line concerns Constable Maggie Habib meeting a handsome firefighter and trying everything to get into bed with him. In the end of the episode, it's revealed that he hasn't touched her because his interests were focused on her colleague, Constable Kevin Goody, who's spent the whole series pining after her. In the last scene they all sit at a pub musing about their love triangle woes.
- In True Blood, many gay men become attracted to Jason Stackhouse, who is straight. Lafayette complains that it's not fair that such a beautiful man like Jason would only be into chicks.
- In Waterloo Road, Phil and Roz find that they're compatible personality wise, and form a relationship which runs smoothly until Roz falls in love with her female teacher. At the climax of this plot point, Phil and Roz agree that since Roz is now a lesbian, they probably wouldn't go well together after all.
- In a Will & Grace episode, Grace encounters a Fag Hag who is in love with her gay best friend, Will's love interest. Having been down this road, Grace tells her that she has absolutely no shot with him whatsoever. She denies it at first before confessing why they can't be together despite their perfect compatibility.
- For that matter, virtually the entire premise for the series ("I wanted to raise the kids to be Jewish; you wanted to sleep with men").
- There are subtle implications and innuendos throughout Young & Hungry that suggest the heterosexual, young, wealthy, good-looking website designer Josh is subject to a crush by his Camp Gay assistant Eliot, and some humor is based around Josh becoming more aware of this and deflecting Eliot's stealthy advances. It may be why Eliot is so snarky towards Josh's new cook Gabi, who had a drunken one night stand with Josh on her first day to their embarrassment. Played for Laughs for the most part as for the first season.
- The t.A.T.u. song Malchik Gay (or Mal'chik Gey, "Gay Boy" in Russian) is about a girl in love with a gay boy who spurns her.
- Amore Si by Tanita Tikaram is a heartfelt evocation of unrequited homosexual attraction where the singer's acceptance of the impossibility of a relationship collides with blind love. Going with a friends-only relationship is tearing the protagonist apart.
- Rihanna's "Te Amo" is about a woman who gets confessed to by another in Spanish. She's not fluent in Spanish but knows what "te amo" means. Nor, of course, is she into girls herself.
- In Ally Hill's Song "In Love with a Straight Girl", Ally advises other lesbians to "let the straight girls be" because if they aren't queer they won't reciprocate.
- White Town's "Your Woman" (later covered by Tyler James), about a straight guy in love with a gay woman, which makes the line "I could never be your woman" kinda obvious. It could also be about a gay man who's in love with a straight man, but either way, it uses this trope.
- "She'll Never Be Your Man" by Chris Cornell. All you can really say about this one is that it's about the bitterness and resentment of being dumped for someone else, but the details are up in the air. Is it about a straight man lamenting that his girlfriend left him for a lesbian? Or is it about a gay man lamenting that his boyfriend left him for a straight woman?
- "Ziggy", from the famous (in France) musical Starmania (known as Tycoon outside of France), a song later covered by Céline Dion, is about a barmaid (who somehow serves as narrator of the musical) who is in love with a very gay fan of David Bowie.
- Also in French, the song "Si j'étais un homme" ("If I Were A Man") by Diane Tell can potentially be read as about a lesbian in love with a straight woman. Some lines, translated:
I would take you on a journey
To see the most beautiful countries in the world
—> We would make love on the beach
While savoring every second
My body swells with flames
Until I fall asleep in your arms
But I'm a woman, and when you're a woman
You don't say those kinds of things...
- Weezer's "Pink Triangle".
I'm dumb, she's a lesbian,
I thought I had found the one.
- Inspired by something that actually happened to Rivers Cuomo, but ironically it turned out to be a case of Mistaken for Gay: He wrote the song after harboring a crush on a girl, then noticing a pink triangle patch on her backpack one day (not "on her sleeve" as the lyrics state). It was only long after he'd already written the song and fallen out of contact with her that he learned that she was straight, and was wearing the symbol to show her support of gay rights.
- Reel Big Fish's "She Has a Girlfriend Now" is about a guy despairing that his ex now only dates women. He offers to get a sex change to appease her, causing the girl to croon, "Oh, that's so sweet!"
- Of Montreal's song "Tim, I Wish You Were Born a Girl".
- At the end of the music video to "Call Me Maybe" by Carly Rae Jepsen, it turns out that the dude she's been obsessing over is gay. This is followed by Carly giving an expression of pure, undiluted "WTF". The guy is interested in the guitarist in Carly's band... who also has a case of Incompatible Orientation.
- This is one interpretation of R.E.M.'s song "Losing My Religion": that it's about the (male) singer's gay crush on a straight man.
- The Pet Shop Boys' cover of Oh Romeo's "Try It (I'm in Love with A Married Man)" changes the perspective from that of a woman in an adulterous relationship to a gay man in love with a married straight man. The video for "Domino Dancing" also appears to depict this trope.
- "Beautifully" by Jay Brannan is about a girl very much in love with a boy who can't return her feelings. Three guesses as to what's holding him back, and the first two don't count.
- An interpretation of Fall Out Boy's "Sugar We're Goin Down" suggests this: the lyrics in the liner notes say "wishing to be the friction in his jeans" instead of the recorded version's "in your jeans". The song also includes references to "watching [a couple making love] from the closet" and "sleeping for the wrong team."
- This happens tragically in the Twist Ending to the music video for K.will's song "Please Don't...". Seo In Guk's character is in love with his best friend, not his best friend's girl.
- Rapper Cakes Da Killa turns this Up to Eleven with his song, "Fuck Ya Boifriend", where he proudly tells a random girl that he wants to fuck her boyfriend. Everything's obviously gonna go well for Cakes at the end.
- "I Found A Girl" by The Vamps:
- In "I Like a Boy in Uniform" by The Pippettes, the protagonist likes a boy but it turns out he's gay. She mopes around for a while but then begins noticing that she likes girls who wear school uniforms too.
- In "She Likes Girls" by Metro Station the singer is trying to date a woman but she's more interested in someone else. Instead of being sad, he tries to hook her up with her crush:
I like you girl, but you don't seem excited
Since she walked in where has your mind been?
You're talking to me, but thinking about her
Your secret is safe, I won't say a word
We should slow it down, I was moving too quick
You don't say you love me, 'just bite your lip
I can read the signals from a mile away...
I know she's on your mind and that's okay
- SLEEPOVER by Hayley Kiyoko is about a girl who has a crush on her best friend. It's implied that the friend is straight, though it's never confirmed.
- "I Wish You Liked Girls" by Abbey Glover is about a girl with unrequited feelings for a straight friend who keeps playing with her feelings.
- Joanie Caucus from Doonesbury had a crush on Andy Lippincott, who turned out to be gay. She was with him when he died of AIDS. Earlier in their relationship she thinks he's married, but he reveals that's not the problem.
Andy: Joanie, I'm gay.
Joanie: There's nothing wrong with that. I'm pretty cheerful myself most of the time.
Andy: No, I mean...
Joanie: Oh my God.
- Harmony from Sequinox tries to flirt with Vivaldi, but he's clearly uncomfortable with it because his civilian identity Caiden is gay.
- Avenue Q: Rod and Nicky. Rod is gay and has a crush on Nicky. Nicky isn't and doesn't. Ricky, on the other hand...
- It's revealed near the end of The Children's Hour, after much foreshadowing, that Martha is in love with her best friend Karen. Karen was engaged to a man most of the play but he broke it off due to fears she was cheating with Martha.
- The Mrs Hawking play series: A big part of why the Hawking marriage is such a disaster is because Reginald is an alloromantic heterosexual, while Victoria is an aromantic asexual.
- Advanced V.G.: Yuuki is a lesbian, who entered the VG Tournamentnote as an excuse to see as many naked women's bodies as possible, and ends up falling for Satomi, who's an athletic 17 year old tomboy. Problem for Yuuki is, Satomi's not only straight, she isn't interested in any sort of romance, period. At least, not yet.
- Invoked in the "Wedding Day Massacre" DLC for Borderlands 2, where Gaige the Mechromancer admits to having a crush on Sir Hammerlock, but no chance of getting him, since he's only interested in men. She does assert she'd be all over him if ever he became straight.
- Krieg is in love with Maya, who doesn't share the feeling due to being asexual.
- Comes up multiple times in Dragon Age: Inquisition.
- Cassandra and Cullen can be flirted with by a female and male Inquisitor respectively, but both will eventually turn them down politely. Cassandra also turns down Sera's interest.
- Dorian can only be romanced by male Inquisitors. He will playfully flirt back with a female Inquisitor, but makes it clear that it can never be serious. (Plus, he's more likely to support a female Inquisitor's interest on Cullen anyway.)
- Sera will bluntly turn down a male Inquisitor and then change the subject. If she is flirted with again after she and the Inquisitor become friends, she more tactfully says that the two of them are too much alike because they both like girls.
- Fallout: New Vegas:
- Implied between Craig Boone and Manny Vargas. When Boone's wife went missing, Manny could barely hide his joy, leading to Boone ending their friendship. Conversation with Manny (particularly if the player has a certain perk) shows that Manny was always jealous of Carla (and her generally unpleasant demeanor didn't win her any favors), though Boone is apparently unaware of his true feelings.
- Corporal Betsy is a Butch Lesbian who shoots down a Courier who tries to hit on her with the Ladykiller perk.
- Cass also gets a bit of this. If the male Courier has the "Confirmed Bachelor" perk, he can make it rather clear to Cass that he is not interested in being more than platonic companions. This text option comes after a potentially flirtatious remark from Cass' end.
- In Fire Emblem Echoes: Shadows of Valentia, Leon is a Camp Gay archer with a huge crush on his best friend, the local Boisterous Bruiser Valbar. Though Valbar cares a lot for Leon and even calls him handsome, he's straight and his wife and child, PLUS his parents and siblings, were murdered by pirates very recently. Naturally, Leon is not going to let his own feelings be known after such a harsh deal; he does imply to Valbar that he has feelings for someone, but doesn't tell him who.
- The Last of Us Both Sam and the Ephebophile David have crushes on Ellie, who is revealed to be a lesbian in the Left Behind DLC.
- Mordin (from an Asexual species) and Shepard in Mass Effect 2. If Shepard keeps going back and talking to Mordin often enough and is not otherwise in a relationship, Mordin will assume that Shepard is expressing "interest" in him, and lets them down gently. Shepard then has the option of saying that their stopping by for conversation so frequently is Not What It Looks Like. Or you can run with it and sarcastically thank Mordin for letting you down easy. Mordin's response to that gives a little Too Much Information.
- It's possible to have Kaidan or Liara run into it with Shepard in the first game. Kaidan finds out if Liara is chosen in the confrontation while Liara may be told one-on-one that Shepard is only interested in men.
- Interestingly, dummied out data indicates Kaiden was at one point at Love Interest for Male Shepard too. If the dummied out dialogue is restored via, Male Shepard can turn down Liara this way too, complete with voice acting.
- Male Shepard can run into this in Mass Effect 3 if they try and hit on Samantha Traynor. Female Shepard can use this to reject Traynor when she tries to seduce her.
- If female Shepard returns to speak to Jack frequently enough in Mass Effect 2, Jack will inform her that she "doesn't swing that way".
- This is implied to be the case if Male Shepard turns down all of the women pursuing him in the first two games and romances Kaidan or Steve in the third.
- Subverted with Kaidan. In the first game, he can only be romanced by a female Shepard. But in the third one, though you can still romance him as female Shepard, you can also choose to upgrade your bromance with him to a full blown romance if you are playing a male Shepard (being in fact the only male bisexual option in the series). Curiously, his female counterpart from the first game, Ashley, does not suffer the same treatment. He explicitly says that he wants to be with Shepard (and this also works for a female Shepard who hasn't romanced him before) because he already cares for them.
- It's possible to have Kaidan or Liara run into it with Shepard in the first game. Kaidan finds out if Liara is chosen in the confrontation while Liara may be told one-on-one that Shepard is only interested in men.
- Mortal Kombat X: Kung Jin implies that one of the reasons he didn't feel like he'd measure up to the Shaolin's standards is because he's gay. This pre-fight dialogue makes it a bit more clear:
Kung Jin: You face a Shaolin.
Tanya: Quite a handsome Shaolin.
Kung Jin: Barking up the wrong tree, sister.
- In the female protagonist's route in Persona 3 Portable, the later ranks of Aigis's Social Link have her lamenting that she's not male and, between that and being a robot, is thus not an ideal love interest for the heroine. Exactly how incompatible she is with the heroine's orientation is to some degree open-ended, but there are no opportunities for the heroine to actively reciprocate her feelings, making it fall more or less into this trope.
- Appears in The Starship Damrey with Large (gay) and Nick (straight). The main problem is that the emotionless computer discovered this and started casually spreading word of it amongst the crew, horribly embarrassing poor Large, although Nick, for the most part seems to have been sympathetic about it.
- Star Wars Legends: Knights of the Old Republic:
- Implied to be the reason Juhani and Dak Vessar had a falling out. They were both Jedi Padawans, but started to have their doubts about the Order. Dak made up his mind to run away, and tried to take Juhani with him, pleading he loved her. Unfortunately, Dak… wasn't Juhani's type.
- The male player character can try to flirt with Juhani. It doesn't work very well; she's openly disgusted in fact.
- In Pillars of Eternity II: Deadfire Eder cannot be romanced by either gender, but if a male character demonstrates a romantic interest in him then he specifically states that he's not attracted to men among the other reasons why he's not looking for a relationship. He does however note that if he's ever curious then you'll be the first to know.
- In the Hidden Block route of Asagao Academy Normal Boots Club the main character asks out Ian aka "Brutalmoose" who, very confused, asks "You know I'm Gay, right?". They do end up going to the festival as friends though.
- Katawa Shoujo:
- In the past there was a failed confession between Misha and Shizune, with the latter being straight or at very least just... well, not into Misha. They do stay as close friends, but as said below, Misha still can't fully let go of her feelings.
- In Emi's route, Hisao thinks the track team captain will be a rival for his affections for Emi, but it turns out that she once confessed to him, only to find out that he's gay. Emi thinks it's hilarious when she finds out and then explains what's going on.
- Hisao can have a sex scene with Misha however it is framed as a terrible idea in the narrative and visual senses, both due to her being gay and because Hisao was dating Shizune at the time, with her desiring "comfort" from him because she can't have Shizune's love while he can. The scene directly leads to Shizune's Bad End.
- Steins;Gate has Luka Urushibara, in love (most likely) with the protagonist Rintaro Okabe, who is alas straight. Knowing that Okabe can never answer his feelings, he sends an email 17 years in the past to make himself be born as a girl. Somehow. One of the endings has them become a couple this way and even having a child.
- Kuon, from XBlaze, is straight note and has no attraction to girls. Elise, from the same game, is a lesbian who is in love with her. Mei even calls Elise an “unfortunate soul” because she is doomed to fail.
- A bizarre inversion in 1/0: So there's never been a fourth wall, and there's very little in the setting except a featureless plain and a bunch of tiny things who chat. Terra would very much like to fall in love with Zadok, but Terra's a lesbian earthworm and Zadok's a male grass golem. She briefly gets a personal fourth wall in order to lose the concept of lesbianism (solely an out-of-universe thing, since none of the characters are human and Terra is the only character with a metabolism), but self-deception is a turn-off for him. The philosopher of the group solves things by successfully arguing that applying the constraints of human biology to people without it is absurd. Love is therefore a function of personalities, and therefore limiting it is a violation of free will and their purpose as characters. Around 1/0, we call this a Tuesday.
- Averted in Arthur, King of Time and Space; although either Tristram or Isolde may be gender flipped depending on the arc, their sexualities will always change to match. Also avoided; in at least one arc, Nimue is a guy, but how this affects her/his relationship with Merlin is never addressed.
- In every arc, though, Galehaute's feelings for Lancelot are unrequited, and indeed unspoken. Although not as unspoken as Arthur's, which were only revealed to the readers in the comic's finale (although the clues were there).
- In Check, Please!, Bitty thinks this is the case when he realises he has feelings for Jack, whom he assumes to be straight.
Bitty: ... It is something I should've learned a long time ago. Never fall for a straight boy.
- One of the omakes to Cross Heart has a boy confessing to Haru. Not only is she gay but she is taken.
Boy: I like you! Please go out with me!
Haru: Huh? B-but you... you're a boy.
Boy: Yeah, I am.
- In The Dragon Doctors, the existence of "orientation adapters" allows people to defy the trope in-universe when appropriate (e.g. following an involuntary Gender Bender inflicted upon one's spouse).
- In Dubious Company, Marty has a tremendous crush on Elly. Both are straight males. Marty has yet to understand the "male" part, despite being repeatedly told by everyone that Elly is a man.
- In Dumbing of Age, Ethan felt like being gay had taken over his life, so he begins dating Joyce as The Beard. Oddly, Joyce has discovered the truth, but they're still dating—largely because she has issues with sex (especially lately) and sees him as "safe," though she seems to slowly be realizing that this won't work long-term.
- Before Joyce, Ethan had been dating his childhood best friend, Amber; they went to prom together and were going to have Their First Time after, but naturally that ended with Ethan finally admitting the truth. Amber tried to be supportive and helped him come out to his family, but her broken heart has made their friendship rocky since then.
- Joyce got this again with Becky, her best friend from back home, who tried to convince herself that Joyce's boy-crazy personality was all an act. She was wrong.
- Girls with Slingshots approaches this situation a few times.
Angel: I'm a lesbian. Our first base is, "she's not straight".
Jim: Oh, that's my "foul ball". I hit a lot of those.
- Heterosexual Jamie and asexual Erin are in love and have a non-sexual romance. Relationship stress ensues when Jamie suffers from sexual frustration, and neither of them wants to have sex with the other.
- El Goonish Shive:
- The sketchbook for 2010-11-30 is the page image, with Elliot (straight) ← Justin (gay) ← Susan (asexual) ← and Catalina (lesbian), all side-by-side on a couch.
- It also has this times five, because Gayngst is one of the things Shive writes well:
Susan: Could've been nice...
- Justin Tolkiberry (a gay male) has Melissa, a straight girl (and his former best friend) who was in love with him and refused to accept that he's not interested. (This changed during the "New and Old Flames" storyline, much to Shive's surprise.)
- Melissa thought that she could "cure" Justin. Currently, she's in a relationship with Noah. He claims that their relationship is a mutually beneficial one "for close comfort and pleasure". It hasn't been stated outright, but the vibes are that Noah is himself gay, or at least bi, and that Melissa saw her relationship with him as some sort of "proof" that Justin can be "cured". Later events reveal that Noah is likely part-Uryom, whose attitudes can range from aromantic asexuals to romantic pansexuals, so it's tough to tell.
- Susan had a crush on Justin before she learned he was gay. Notably, they're still very close, relate to each other very well, and during the Gender Bender party (which turned Susan into a bisexual man and Justin into a straight woman) they had a heartfelt moment which almost escalated into something they would have regretted.
- Justin himself is in love with his male friend Elliot Dunkel, who's straight.
- Worse still, when Elliot is in his "mild-mannered girl" form he finds himself attracted to Justin. Making this an Incompatible Orientation situation twice over.
- Nanase's relationship with Eliot turned out to be a case of this. Nanase liked him but wasn't really physically attracted to him. When she learned of Sarah's crush on Elliot, she ended the Love Triangle in short order by breaking up with Elliot and admitting she had just been going through the motions. Nanase didn't really consider the ramifications of this, until Elliot accidentally created an Opposite-Sex Clone that Nanase found disturbingly attractive.
- Catalina later falls in love with Susan; the latter still wishes to be friends however. Susan even had an Imagine Spot about a date with Catalina, but she's well aware she's straight.
- Susan herself expresses 'strangst' (straight angst) in an early appearance, wishing she were a lesbian because of her and her mother's issues with men. (Susan's mother is saddened that her daughter isn't attracted to women. This is mostly due to a traumatic event in Susan's childhood when she discovered her father was having an affair.)
- Homestuck has a complex series of intra- and inter-species romantic incompatibilities.
- A traditional human version of the trope occurs in Universe B-2: Roxy has a crush on Dirk, who is gay. She knows, or at least suspects, that they're fated to have kids together. Too bad about the "ectobiological cloning" thing... Dirk in turn has a crush on Jake, who is still figuring out whether he's straight or bisexual. Later, Dirk tells Jane with uncharacteristic sincerity that he truly wishes he could reciprocate Roxy's feelings because it would make things much easier for everyone involved, but his love for her is completely platonic.
- Alternian society is binormative so gender is rarely a dealbreaker for trolls, but other types of incompatibility are still possible. Karkat develops a doomed same-sex hatecrush on John. To heterosexual John, the fact that they're both guys is the biggest issue with this. To Karkat, whose native language doesn't even have a word for "orientation", what's much more problematic is that as a human John lacks any concept of romantic hate. The interspecies romance between Dave and Terezi falls apart not because of the troll partner's bisexuality but because of their polyamory. The monogamous human partner was not prepared for the troll norm of polyfidelity.
- The Squared Sprites. Jasprosesprite was extremely interested in Nepetasprite until she merged with Davesprite. After the merger, the new Davepetasprite is actually more receptive to those advances but the Rose half of Jasprose finds that, even mind-melded with Nepeta, Dave triggers her incest taboo.
- In Khaos Komix, early on in Charlie's and Tom's friendship Charlie confessed to Tom. Being gay, he turned her down. Charlie got over it quickly and they're platonic friends current time.
- Magick Chicks: Subverted in Faith and Tiffany's case. It initially seemed as if Faith didn't have a shot with her, since Tiffany is straight. Plus, she regards Faith as her enemy. Despite this, she agreed to go on a spa date with her, which ended in a kiss between them. Still, she remained adamant about not being attracted to other girls, which she isn't. But she eventually reached the point where she could no longer deny being attracted to Faith. Confirmed by the comic's editor:
T Campbell: "For instance, there was some debate about Tiff's sexuality, and for awhile the committee resolved that she was straight and knew it without doubt, putting Faith in the unusual-for-her position of courting someone who would never, could never, return her affections. We changed our tune on this somewhat, though I think the evidence that Tiff is attracted to guys is fairly conclusive."
- The straight pop star Stasia in Marry Me is adored by her lesbian fangirl Parker, who doesn't stand a chance. At an inopportune moment during a concert, Parker hands off her 'marry me' sign to Guy, her male, heterosexual best friend. Stasia is still emotionally unstable from her last breakup, and ends up accepting Guy's "proposal".
- Discussed at length in Meaty Yogurt with a subplot about a man who cannot get over his feelings for a lesbian waitress. At one point he speculates that finding every woman he likes is a lesbian makes him sorta a lesbian in a man's body. The object of his affections assures him that being a lesbian never coincides with finding every woman you like is a lesbian. Ever. In the history of the universe.
- In Ménage ŕ 3:
- Gary is smitten with Yuki on their first meeting. Zii informs him (apparently correctly) that Yuki is not actually gay, she just only sleeps with women. Later, in fact, Yuki finds herself returning Gary's feelings, and makes efforts to get over her ... complicated personal issues.
- For a more straightforward case — Dillon, Gary's former roommate, has a hopeless gay crush on straight Gary.
- Dillon's infatuation with Gary remains somewhat active after he gets his own comic, Sticky Dilly Buns. Likewise, his roommate Amber continues to display a fondness for him that would pretty clearly turn physical given half a chance — especially as she knows that Dillon is a master of a special oral sex technique.
- Chad Dracul in Muertitos is lusted after by pretty near every girl in his school, but is himself asexual.
- In Narbonic, Artie realises he's gay when he's attracted to ANTONIO SMITH FORENSIC LINGUIST!, who is "married to grammar. And actually married."
- Oglaf, being a (very NSFW) sex comedy comic, has this in spades. Recurring offenders are Ambassador Sandoval's desire for strictly straight Ivan the Apprentice, and the various men (and odd shapeshifter) trying their luck and getting shot down by snarky lesbian mercenary Greir.
- The Order of the Stick; Elan tried to break out of prison once by using an illusion of a woman to seduce the guards. This failed due to one guard being married and the other being gay.
- Out There has more than one.
- In Queen of Wands, bisexual Angela has a thing for her straight best friend Kestrel. It becomes a major point near the end of the comic, nearly ending their friendship.
- In Questionable Content:
- Tai often complains that of all the attractive lady friends Marten has, he's dating the only one who is into girls. After Marten and Dora break up, Tai and Dora get together, once Dora is ready to date again and Tai checks that Marten is okay with it.
- Marten's parents still care deeply for each other but just couldn't bear to remain married after Marten's dad came out of the closet. Although the divorce was quite painful for everyone involved, by the time of the comic they're Amicable Exes and Marten's mother gives the speech at his father's second wedding.
- Alpha Bitch Zoey Irwin from Sandra and Woo is revealed to be infatuated with her friend Michelle who, in turn, is crushing on Cloud Williams. Michelle is furthermore not a part of the gay-acceptant faction of humanity, much to Zoey's dismay and despair.
- In Scandinavia and the World, Sister Finland has a thing for Sweden, who is in a committed relationship with his boyfriend Åland. It doesn't go quite like you'd expect, though, since she's either unaware of his true orientation or doesn't really care, and he knows her to be a stoic psycho who probably wouldn't take no for an answer (at least not without killing him in the process), so he reluctantly accepts it to the point that he has a kid with her to hide his homosexuality (since he also has, or at least had, issues with accepting his preference and having people know about it). Åland, meanwhile, seems mostly unaware of it, only appearing to know anything about it at the christening of the child (and being as shocked as you might expect). Since the relationships between characters are loosely based on how the nations they represent interact with each other in real life, though, it's fair to expect that this Love Triangle has some plot holes for the sake of comedy (though it's also possible that Åland knows how Sister Finland is and understands Sweden's difficult position).
- Leslie Bean has a habit of developing crushes on girls who don't swing that way, although once she managed to be an exception.
- Robin had a crush on Ethan back before she (or he) realized he was gay.
- Malaya and Ultra-Car developed a close relationship, but the former is a Robo Sexual while the latter is asexual and finds sex (or really, any human biology) gross. They eventually find a way around it. (Basically, it turns out the sex Malaya wants is less "involved" than Ultra-Car expected.)
- In Something*Positive, PeeJee nursed a crush on Jhim (gay) for years.
- PeeJee is established as having this as a near-superpower, up to and including precognition. At one point, one of her ex-boyfriends, a lying scumbag who cheated on her with different women, later comes out as gay after they break up.
- A short, three-strip story has Jhim ask out a somewhat mannish woman who looked like an attractive male from behind. He tells PeeJee that they got along really well; if only she were a man! (PeeJee, naturally, is annoyed.)
- What Could Have Been: Apparently, this lesbian was originally supposed to be a recurring character whom Davan would have feelings for. Word of God said that he made up the PeeJee/Jhim thing when he decided against it.
- Vampire Cheerleaders: Even though Zoe vehemently denied it for most of the series, vol.4 confirmed she did have the hots for Suki. But the feeling wasn't mutual. Suki was put-off by Zoe kissing her and even moreso when Zoe humped her leg in front of everyone at the amusement park.
- A parody short posits that the reason Sonic the Hedgehog makes such fast tracks when Amy's around is because he doesn't have the heart to tell her he and Tails have long since passed the point of goo-goo eyes. Amy is not impressed.
- It's later revealed that this was another scheme of his to keep her away, though when he later needs her help to avoid certain death she decides she's had enough and angrily dismisses him.
- More than one guy has made passes at Phase in the Whateley Universe. His entire team (and his girlfriend) know that he is really a heterosexual, heteromantic guy trapped in a mainly-female body.
- Death Note: The Abridged Series (kpts4tv): Butch Lesbian Rem is in love with Misa, who is in love with Light, who is in love with L, who is "snack-sexual". Also, after Mikami abandons Takada she considers going out with Light, but then remembers he's gay. Rem later ends up with Misa by possessing Mogi and Jumping the Gender Barrier.
- In Glowfic, The Kanim template tends to end up pining for Bells, whose orientation is not compatible with their gender, for example the original Kanim with Glass, who is lesbian. Also happened briefly between Shell Bell and Pearl, but Shell Bell managed to make an exception.
- Resident Evil Abridged turns Wesker's homoerotic obsession with Chris into a full-blown unrequited crush, since Chris is straight and implied to have the hots for Jill.
- In Strong Bad Email #8, Strong Bad gets an email talking about how hot he is and how the sender would like to go out with him... that turns out to be from a guy named Brian. Strong Bad bluntly replies "Look, man, unless Brian is short for... Brianrietta or Brian-Sue or something like that, it's just not gonna work out between you and me, okay?"
- For the Web Serial Twig, see the Literature section above.
- In an episode of 6teen, Caitlin confesses to being a co-worker's secret admirer, only to find out Kevin "plays for the other team".
- As Told by Ginger: According to Urban Legend of Zelda, Courtney was going to confess being in love with Ginger, who would turn her down because of this trope, but Nickelodeon nixed the idea. Supposedly Word of God said this at a con, but no hard evidence seems to exist.
- Futurama had Leela flirt with a Muscle Beach Bum who is a.) a professional beach bully (he lets guys beat him up to impress their girlfriends) and b.) is gay, anyway.
- The Simpsons:
- Mr. Burns to Smithers.
- In another Simpsons episode All's Fair in Oven War, Marge hires a contractor to fix Homer's botched kitchen renovation. Homer overreacts of course, and thinks he will lose Marge to the contractor. When he tells him to go ahead and kiss Marge, the contractor explains that he is gay. But he has a contractor that handles that sort of thing.
- An early South Park episode had every boy in class develop a crush on their substitute teacher; Chef, likewise, managed to strong-arm her into a date, but the next day told the kids that she was a lesbian. The boys don't know what that means, so Chef simply explains that lesbians will only date other lesbians. Naturally, the boys thus decide to try and become lesbians.
- In the episode parodying Queer Eye For The Straight Guy, Mr. Garrison gets frustrated because all the straight men in town have embraced the metrosexual craze and are now dressing and acting Camp Gay, so he and Mr. Slave don't know who to hit on anymore.
Garrison: JUST WHAT THE HELL IS GOIN' ON HERE?! WHY WON'T ANYBODY POUND MR. SLAVE'S BUTT?!
Randy: Well, we don't pound butt, Mr. Garrison. We're straight.
Garrison: THOSE PANTS AND THOSE SHOES SAY YOU POUND BUTT!
Jimbo: Hey, now that's not true! My shoes don't say I pound butt.
Garrison: NO, YOUR SHOES SAY YOU TAKE IT IN THE BUTT!
- Played With: When Garrison decided to get a sex-change operation, it ended his relationship with Mr. Slave, who is, you know, not into women.
- In the episode parodying Queer Eye For The Straight Guy, Mr. Garrison gets frustrated because all the straight men in town have embraced the metrosexual craze and are now dressing and acting Camp Gay, so he and Mr. Slave don't know who to hit on anymore.
- Steven Universe:
- Mayor Dewey has expressed some attraction to Pearl, who was deeply in love with Rose Quartz and later showed interest in "Mystery Girl". She doesn't seem to notice his crush on her.
- Heck, this might have been the reason that Pearl/Rose never sailed, since Rose ultimately chose Greg, and at one point Pearl specifically mentions "men" whom she dated before him. Word of Saint Paul has implied that Rose had some kind of feelings for Pearl, though.
- One could theoretically put Jamie/Garnet here too, though that's complicated by the fact that Garnet is not only into women, she's actually two women herself.
- Actress Lea Michelle joked about the fact that her father once told her that of all the men in her life, the only one that was worthy of her was her best friend and (Spring Awakening and Glee) co-star Jonathan Groff. It is easy to see his point.
- Herman Melville's attraction to Nathaniel Hawthorne.
- Robert Lowell's love for his close friend, Elizabeth Bishop.
- Mixed-Orientation Marriages of the type where a person who is in the closet about their exclusively homosexual nature is married to someone who's heterosexual. Now also called "brokeback marriages" after more recent famous fictional examples.
- A depressing fact of life for many queer teenagers. Since only a small portion of the population is gay or bisexual, there's a strong chance that their crush will have an incompatible orientation, and asking about compatibility may be out of the question if they live in one of the many areas that are hostile to homosexuality. On top of that there's the universal problem of mutual attraction. Adulthood usually offers more options for meeting people of compatible orientation but doesn't change the basic fact of queer sexualities being a minority.
- It's also a cliché that straight girls involved in theatre or music in high school will inevitably crush on at least one closeted gay guy.
- The dating website OkCupid installed a feature where gay and bi users can keep their profiles from showing up for straight people; one of the reasons was that a lot of straight users were attempting to date attractive gay members of the opposite sex on the site.
- Can happen between members of the Furry Fandom: one, a "light" fur who enjoys the fandom for fun but prefers their romantic partners to be of their own species, develops a crush on a fellow fur who's only interested in anthropomorphic animals and thinks Humans Are Ugly.
- Relationships between transgender people and their partners can end when they come out of the closet, and their partners' orientation doesn't match with their gender and/or new looks.
- Hand-raised birds often imprint on humans. When they get older, hormones drive them to take a mate, but as they believe themselves to be humans, their desired mate is usually their caretaker (who is usually not interested in birds that way). This can prove problematic if the bird in question is intended to be used for breeding, as they show no interest in mates they could produce offspring with - even if their intended mate puts on a dramatic courtship display. Other problems can arise, too, as the bird becomes increasingly frustrated that their attempts at pairing with a human aren't working; they may become aggressive to their caretaker ("How dare you spurn me!") or to others the bird perceives as competition.
