->''"You people and your quaint little categories."''
-->-- '''Captain Jack Harkness''', ''Series/{{Torchwood}}''

On many mainstream TV shows, there are NoBisexuals. Not just in the casts, ''anywhere''--once a person has [[SuddenlySexuality realized his or her attraction]] to the same sex, the opposite sex is expected to be discarded utterly. A bisexual, at best, is either a [[AnythingThatMoves kinky guest star]] or [[DepravedBisexual the one who did it]].


This is the ''other'' extreme: Everyone Is Bi. Gender--aside from a few token comments--is hardly a factor in the characters' relationships; the [[JumpingTheGenderBarrier gender barrier]] seems an alien concept.

What this trope is ''not'' is, for example, ''Webcomic/UmlautHouse''. While about half the cast is bisexual, the other half is explicitly not--and even if the ratio were different, the fact that [[HaveIMentionedIAmHeterosexualToday neither half will]] ''[[HaveIMentionedIAmHeterosexualToday shut up about it]]'' makes it the antithesis of this trope, in which it's rarely, if ever, mentioned at all.

If people are canonically straight, but fanfic portrays them as otherwise, it's EveryoneIsGay (even if they're stating that the characters are bi--it's a NonindicativeName).

In video games where you can choose your gender, this trope is increasingly common--not out of any desire to make a particular statement about the characters, but because game developers and writers don't see any reason to cut off romance-related content just because of gender selection (especially since doing so would involve more work, and people are lazy).

Common in works set in TheFuture. Even if the setting isn't a full-blown FreeLoveFuture, there's a good chance that both monosexuality will have been left in the dust along with [[OutgrownSuchSillySuperstitions those silly superstitions]], usually for the same reason: to signify that this society is more "advanced" and "enlightened" than our current one, only in terms of social progress rather than intellectual progress.

While it's not TruthInTelevision, it ''is'' truer than people often think. People can be attracted to either gender (or [[{{Asexuality}} neither]]), and if someone's previously expressed an attraction to their opposite gender, bisexuality is generally the safer assumption. If you're counting homoflexibility and heteroflexibility, then there certainly are '''lots''' of bi people--but still, not '''everyone''' is bi.

If one were to [[InvertedTrope turn this trope upside-down]], then either there are NoBisexuals, or [[NoHuggingNoKissing everyone is asexual]]. Compare CastFullOfGay.



[[folder:Anime and Manga]]
* ''Anime/RevolutionaryGirlUtena'': The TV series contains suggestive scenes and dialogue between nearly ''every'' pair of major characters, [[BrotherSisterIncest including siblings]] and completely regardless of gender. The director kept pushing the envelope until not even the most die-hard of HaveIMentionedIAmHeterosexualToday fans could call it "just HoYay". Even the manga artist, initially disinterested in the plan for girl-girl intimacy, came around near the end of the series. The brakes came all the way off for the TheMovie, where the main couple went from the heavy subtext of the series to unambiguous lesbian romance.
%%* The second half of ''Manga/{{Gravitation}}''.
* Seems to have been the general assumption in ''LightNovel/KyoKaraMaoh'', as it is 'not uncommon' for two men to marry, and the maids who have a betting pool on the main character's relationships don't even take gender into consideration despite his having explicitly stated his heterosexuality several times. [[TransparentCloset Or perhaps they just know better.]]
* It seems like absolutely everyone in ''Manga/AxisPowersHetalia'' is at least bi, which is pretty much what happens when 90% of the cast is male but romantic/sexual tension between the characters is still desired. At the very least, WordOfGod has confirmed that France is bisexual and Sweden is [[SingleTargetSexuality gay for Finland]] (probably alluding to how [[NationalStereotypes Finnish people sometimes stereotype all Swedish men as gay]])
** This extends to the women, too. Hungary, Liechtenstein, Taiwan, Seychelles and even Belarus have shown interest or have been {{Ship Tease}}d with both male and female characters.
** FanFic often portrays bisexuality as an integral part of being a nation, since technically they don't count as normal humans ''and'' they've been around for enough time to not be fazed by same sex relationships any longer.
* ''Manga/KaguyaHime'': Mostly everyone but not only because of [[EvenTheGuysWantHim Miller]] and [[EvenTheGirlsWantHer Akira]]. Except for [[PsychoLesbian Maggey and Mayu]], who both definitely think men are dicks.
* In ''Anime/{{Mnemosyne}}'', the entire issue of gender in sex is just discarded. For example, the main character Rin has shown to have sex with both males and females, with [[spoiler:the one person she's loved for over a millennium being the guardian of the Tree]], and the rest of the cast is implied to simply go with what feels good to them. That said, however, gender is an issue to the greater storyline... [[spoiler:well, actually it's rather the ''mix'' of gender that's important. The point? The only character with real tangible power in the entire anime is a hermaphrodite, Apos, at least until Rin becomes the new Guardian.]]
* ''Manga/GorgeousCarat'': Characters' sexualities are never addressed (except for a couple "are you gay?" jokes at Ray's expense). [[EvenTheGuysWantHim The guys just all want Florian.]]
* ''Manga/VampireGame'': ExactlyWhatItSaysOnTheTin, with the exceptions of Darres, Falan, Vord, and Ishtar, several of which still encourage all sorts of bizzare matchups.
* While almost ''any'' manga by Creator/{{CLAMP}} may qualify, ''Manga/CardcaptorSakura'' in particular stands out, what with most of its main characters having both opposite-sex and same-sex attractions.
* ''Dutch'' manga ''Penny Diary'' [[UpToEleven turns this up to eleven]] as not only is bisexuality such the norm that [[FunetikAksent "uniseksuals"]] ([[YaoiBoys a pair of classmates,]] the main character's straight best friend and [[LipstickLesbian an aunt]]) are seen as a harmless quirk while casual sex is encouraged between anyone from [[IncestIsRelative family]] (holidays traditionally ending in a post-dinner orgy,) [[HotForStudent teachers with students]] and Mall Santa (St. Peter) and [[BiggusDickus Black Pete.]] ''The age of consent in the series is 4 and drawn in a chibi style.''
* Seems to come with the badge if you are a male police officer in ''Manga/{{FAKE}}''.
* In ''Literature/FromTheNewWorld'', all of the main characters except Mamoru. When they're 14, their entire class (save him) appear to be in a relationship with someone of the same sex. It's also a case of NoHeterosexualSexAllowed at a young age.
* While structured heterosexual and homosexual relationships certainly do exist in ''Franchise/SailorMoon'', the main characters (Usagi, in particular) are just as likely to blush and be smitten with a beautiful member of the opposite gender as they are someone of the same gender. The series in general also seems to have no stigma in-universe when it comes to straight or gay relationships, as long as the relationship is romantic in nature, it is considered perfectly acceptable (even if said relationships occur between the villains).

[[folder:Comic Books]]
* In ''ComicBook/StrangersInParadise'', most of the female characters have slept with each other, [[HaveIMentionedIAmHeterosexualToday even if they self-identify as straight]]. However, even if they [[DoesNotLikeMen do not like men]], [[IfItsYouItsOkay they have also slept with David]]. LoveDodecahedron does not even ''begin'' to describe it, and it is one of the only series to have the characters ''themselves'' actually suggest multi-partner pairings in order to [[OneTrueThreesome deal with the results.]]
* Wendy and Richard Pini, creators of ''ComicBook/ElfQuest'', have explicitly stated on several occasions that every single elf in the series is at least potentially bisexual. Although most of the characters seem to express a preference for one sex or the other there are several examples of elves in heterosexual relationships taking time out to have same-sex flings as well, perhaps the most notorious being [[http://www.p-synd.com/wild/lndance.gif Leetah and Nightfall's nude dance]] in Volume 5 of the collected series.
* Similar to the [=51st=] century in ''Series/DoctorWho'', the eponymous superhero of ''[[ComicBook/TheAuthority Midnighter]]'' turned down the advances of a woman from the [=96th=] century [[SorryImGay because he's gay]], only for her to be confused because she's never heard of this "gay" thing before. At this point in time, the entire human race has been 100% bisexual for so long that both straight and gay have become entirely forgotten concepts.
She mentions two of her male squad mates had been a couple for over a year after their girlfriends dumped them for each other. Midnighter thought this was hilarious because it meant all of the {{Heteronormative Crusader}}s in his own time are just wasting their time fighting a battle they will inevitably lose.
* In Creator/AlanMoore's ''Comicbook/TheLeagueOfExtraordinaryGentlemen'', the character of Orlando is definitely bisexual, but this makes sense because Orlando is an immortal who changes sex randomly and without warning. However, pretty much all of the female characters (be they historical or mythological) that Orlando spends any amount of time with are bi for Orlando. This includes Mina Murray, the heroine of the series, Fanny Hill, Venus (of course), Marguerite Blakeney and others. And when Orlando is a male, it's at least hinted at and also sometimes explicitly stated that many of his male companions are bi for him also.
** In ''Century: 1910'', Mina, angry with both Orlando (who's male at this point) and her partner Allan, announces that she'll be in self-[[ExiledToTheCouch Exile To The Couch]], and they'll have the bed to themselves. She also comments that she likes Orlando better when (s)he's female.
*** In ''Century: 1969'', Orlando, who's in the middle of a transformation from male to female, offers to let a sexually-frustrated Allan have a go at them. Allan takes them up on this offer.
* In ''ComicBook/{{Artesia}}'', all the Daradjan women seem to be bi, and the men at least have no problem double, triple, or even quadruple-teaming a willing woman. No male characters have yet been shown to be explicitly bi or even homosexual, though.
* In Jaime Hernandez's "Locas" stories in ''ComicBook/LoveAndRockets'', practically every female character is bi, even the lesbian-identifying ones. Except for Vicki, who's a homophobe.
** One of the ''Palomar'' stories features Guadelupe, still reeling from Doralis' coming-out, wandering around and hearing seemingly everyone else confess to having some same-sex attraction.
%%* Every female in ''ComicBook/CherryComics''.
* Save [[TwoferTokenMinority Penny,]] this basically applies to the women in ''The Adventures Of Olivia'' as even if they haven't been ''seen'' making out with other women, it's more of a sense that they ''would,'' but there's only guy(s) around. [[RuleOfSexy Basically, if you're hot, you're getting some, too as far as they're concerned.]]
* Pretty much everyone in ''GraphicNovel/LostGirls''.
* [[ComicBook/WonderWoman Themiscyra]] doesn't have sexual orientation as a concept. Most Amazons end up in homosexual relationships because it's a LadyLand, but that doesn't mean that Amazons won't be equally attracted to men if that's an option.
* Within ''Comicbook/TheWickedAndTheDivine's'' CastFullOfGay, five out of thirteen of the protagonists are bi, six if you count [[IfItsYouItsOkay Ammy]].

* Choose two characters in all of fiction. There is a fic pairing those two. Now notice how gender was not specified in the prompt. That is because everyone can be bi in FanFiction.
* The slight majority of the shipping fanfiction about ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' is generally female on female pairings. Predilections of the fanfic-writing fanbase aside(see above), the fact that the cast is a good 80% female is a big factor. However, the use of humans, OCs, crossovers, as well as RuleSixtyThree have created plenty of heterosexual ships. Females becoming paired up with characters such as Soarin, Dr. Whooves, Big Macintosh and Spike have become more popular as well. As a result, the shipping fandom of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' can be equated as this.
** Some stories, in particular, take advantage of this trope; in ''Fanfic/TwilightsList'', Twilight Sparkle expresses interest in both stallions and mares, and when she considers asking her friends out on a practice date, she doesn't even consider the possibility that they may not be interested in mares themselves. Then again, it may have simply been her not thinking about it, because it wasn't supposed to be a ''real'' date...
** ''Fanfic/{{Green}}'' relies on this as everyone--down to the Princesses--expresses interest in mares, and several characters express interest in (or reminisce on past experiences with) stallions as well.
* Everyone in the That Damned MPreg universe is bi unless specifically stated otherwise, exclusively straight and gay characters are few and far between.
* ''Fanfic/MyImmortal'': This seems to be the case, though only the guys show it, per the author's opinion that GuyOnGuyIsHot. For the girls, it's just an InformedAttribute. Ebony herself flip-flops between BiTheWay and HaveIMentionedIAmHeterosexualToday for no adequately explored reason.
* Absolutely everybody in ''WesternAnimation/KimPossible'' fanfic, DependingOnTheWriter.
* In C'hou across ''Fanfic/WithStringsAttached'' and ''Fanfic/TheKeysStandAlone: The Soft World'', there are no sexual taboos among the C'hovites and outworlders; hence, Everyone Is Bi. For example, when Ma'ar asks George to sex with her, she tells him to invite the others in and they'll all enjoy one another. (Given that the four are firmly heterosexual, George agrees to sex but asks to leave the others out of it.) Grynun says that inside the castle walls, the four can have sex with each other but with none of the Idris until she has them first. And As'taris ogles the naked Paul and comments to Grunnel that if he'd known what he was missing, he wouldn't have treated Paul so indifferently.
** This doesn't apply on the Hunter's world; he talks of the “shameful female-men.”
* In [[http://archiveofourown.org/series/25778 this]] ''Series/TeenWolf'' fic, Lydia, Jackson, Scott, Allison, Stiles, and Derek are all bisexual and part of a queer advocacy group that Lydia starts because their college's actual LGBTQ group isn't very accepting of [[NoBisexuals bi]] and trans people.
* In the ''Main/ObserveTheViewingGlobe'' fan work archive for the ''Franchise/PowerRangers'' fandom, this can be easily [[HandWave handwaved]] by the fact that Rangers whose powers connect them directly to the Universal Morphing Grid frequently face a MateOrDie scenario due to the Morphing Grid messing with their hormones (i.e. causing "trips" or "spikes" of sexual arousal) as a side effect of holding the Power. The Morphing Grid also causes Rangers, regardless of gender, to feel "sympathy spikes" of hormones in response to the close proximity of horny teammates, so that any Ranger who experiences a hormone spike has at least one teammate, at any given time, to whom he/she may turn for release.
** As masturbation is not considered a viable release mechanism to those who hold the Power, it's very fortunate that the Morphing Grid appears to grant immunity to [[FantasyContraception pregnancy]] and [[STDImmunity venereal disease]] for Rangers on active duty.
* ''Fanfic/WeissReacts'': Everyone except [[OfficialCouple Cardin and Melanie]] seems to be bisexual. Ren and Nora have had ShipTease with other characters of the same gender, Weiss had a crush on Jaune, Pyrrha is implied to crush on Weiss, and so on. Glynda is the greatest example of this; despite ostensibly crushing on Ozpin, she spends half of her own story secretly [[SuspiciouslySpecificDenial not crushing on]] Cinder, [[Anime/{{AKB0048}} Chieri]] and Yin.
* ''Weaponized'' in [[https://www.fanfiction.net/s/12128915/1/The-Edit-War-for-Ash-s-Freedom-to-not-be-Betrayed The (Edit) War for Ash's Freedom to not be Betrayed]]. During said edit war between the Pokemon god Arceus and the mysterious Darkern Edgier, Darkern changes reality, as part of his plan to make Pokemon 'better', to have all the females of the world be Bisexual, however, he doesn't specify females. When Arceus points out that he has made Ash bi, as well as all of his male rivals and thus, per Darkern's earlier logic, canonized such pairings Darkern has a VillainousBreakdown.

[[folder:Films -- Animation]]
* In ''WesternAnimation/SausageParty'', [[spoiler:there is an orgy scene where all the food characters have sex with each other, regardless of gender.]]

[[folder:Films -- Live Action]]
* ''Film/BedroomsAndHallways'': The premise of the film is that sexuality is not set in stone.
%%* ''Film/{{Gia}}''
* ''Film/TheRockyHorrorPictureShow''. In fact, this is pretty much the entire ''point'' of the movie.
* ''Film/VelvetGoldmine'' has Brian and Mandy and a host of glam rock fans.
* While it's never shown onscreen, the script for ''Film/{{Alien}}'' was written with the idea in mind that all of the crew members would've banged without regards to gender, except [[spoiler: [[RidiculouslyHumanRobots Ash, who [[BarbieDollAnatomy couldn't]] even if he wanted to.]]
* The extraterrestrials of ''Film/{{Paul}}'', at least according to Paul. He also says "It's all about the pleasure."
* Most mainstream porn, of course, meets this trope halfway--it's true by default for women, but not for men. (There's a fairly small subgenre where it's true across the board.)
* In ''Film/SixTheMarkUnleashed'', the Community's holographic program instructs new initiates of the [[MarkOfTheBeast Holy Implant]] that with the New Order brought about by [[TheAntichrist the Leader]], things such as monogamy have been done away with so that people are free to move about with partners of either sex. Procreation is only allowed according to the will of the Leader.
* ''Literature/{{Crash}}'': Almost all of the lead characters (save for Catherine) are seen having sex with both men and women, including Ballard, Vaughan, Gabrielle and Helen.

[[folder:Light Novels]]
* Katarina has eight named love interests in ''LightNovel/DestructionFlagOtome'', three of whom are girls that originally should have been in love with one of the five boys. This isn't considered unusual by anyone and one of the girls, Mary, is one of Katarina's most aggressive suitors. While not all the boys realize that they're competition, those that do don't find it strange at all. It's also noted that Nicol, one of the boys, has a lot of male fans as well.

* In ''Literature/ABrothersPrice'' it is hinted at that premarital relationships to women are nothing unusual. Exactly how common this is remains unclear, but Jerin is not at all surprised when Cira mentions a female lover in her past. There are also female prostitutes for women, although those do pretend to be male, so there might be an overlap with SituationalSexuality.
* The Mina Davis books ''[[Literature/HungoverAndHandcuffed Hungover and Handcuffed]]'' and ''[[Literature/AssholeYakuzaBoyfriend Asshole Yakuza Boyfriend]]'' are somewhere between this and CastFullOfGay. More than half of the main cast is bi (though in some cases only by WordOfGod), but several are of them are gay. A few are straight, though none explicitly so.
* In Creator/MarionZimmerBradley's ''Literature/{{Darkover}}'' series bisexuality is very much a social norm on the titular planet. In fact, in many cases, it is actively encouraged, especially among adolescents who are too young to marry and same-sex relationships serve to help prevent teenage pregnancies. Also, as expectation of monogamy is rather lower on Darkover due to it having originally been a LostColony with a small initial population, even adults who are married may have ongoing extramarital relationships with people of the same or opposite sex. Because of the age of these works, this was sharply contrasted with the Terran Empire, which reflected more mainstream American social values of the time and thus, despite the setting being in the distant future, had mid-20th Century sexual values. Terrans frequently found Darkovan sexuality more than a little discomforting.
* In the ''Literature/KushielsLegacy'' series, every single d'Angeline character is bisexual. But in other countries isn't the case--or at least, if it is their cultures don't allow them to express it. Much of the story is spent in countries other than Terre d'Ange, and sometimes this is a point of CultureClash.
* In Creator/DianeDuane's ''Literature/TheTaleOfTheFive'' fantasy series, bisexuality is culturally universal in the world it takes place on.
** To the extent that they have laws dictating that everyone must have at least enough heterosex to produce a couple of children. After that, they can go back to their real loves.
* In Creator/PiersAnthony's ''Literature/ApprenticeAdept'' series, the serf class on Photon can be inferred to be mostly bisexual--mostly out of having to cater to the whims of the Citizen class (lead character Stile mentions "consensual heterosexual encounters", implying there's been homosexual ones and possibly voluntary). There are however, only two verified bi characters (Tania and Tsetse--naturally both female and hot.)
** Note that this only became the case [[AssPull in the last book.]] Prior to that, homosexuality was barely even sidebarred.
* In the Literature/MerryGentry series, pretty much all of the Fey are supposed to be openly bisexual. Merry herself is all about the heterosex, of course, so that she can [[AuthorAvatar reflect the author's own feelings]] about sex with another woman, which seem to be "ewww gross but that's actually kind of interesting".
* In Hamilton's other series ''Literature/AnitaBlake: Vampire Hunter'' the number of minor and major male characters who ''aren't'' bisexual can probably be counted on one hand (and there are quite a few male characters) including just about every one of Anita's love interests. Interestingly it is made very clear more than once that Anita herself is not interested in women and most of the female characters that are tend to be pretty villainous.
* In S.M. Stirling's ''[[Literature/TheDraka Draka]]'' novels, the old 20th-Century genetically-unmodified-human Draka are straight, gay, or bi as the case may be (and with no shame or self-consciousness about their orientation ever); but the genetically-engineered New Race or ''Homo drakensis'' Draka, portrayed in ''Drakon,'' are all bisexual (and their sexual appetites always ravenous).
* Literature/AnneRice's ''Literature/TheVampireChronicles'':
** Lestat is absolutely bisexual; he has an intense love affair with his male best friend before becoming a vampire (nothing subtextual about it; they kiss multiple times, live and sleep together, and are strongly implied to have sex), and harbors deeply erotic thoughts about him even after the transformation. Considering the nature of his inclinations and relationships afterward, it's pretty obvious that he retains a pronounced attraction to men even after his ability or desire for physical sex is lost when he becomes a vampire.
** In Armand's book, she finally had the main character have sex with persons of both genders before he was turned.
** The same author's ''Cry to Heaven'' runs on this trope. The main (castrated) male character has love affairs with people of both genders, although his same-sex relationships are more numerous and generally more dwelt upon by the author. His two most lasting affairs are with another castrated man and a woman, respectively, and he thinks of both of them as the loves of his life at different points in the novel. He even carries on a sexual relationship with a cardinal in Rome, who (at first) justifies the affair with the church's belief that castration renders the person neither male nor female, and thus [[TooDumbToLive a loophole to rules about celibacy.]] It doesn't last.
* Creator/LarryNiven's ''Literature/KnownSpace'': According to one interpretation, which is in line with the way the Puppeteers themselves generally explain it to non-Puppeteers, Pierson's Puppeteers can be regarded as an entire race of bisexuals. Males are sapient and produce gametes, while females are non-sapient and provide gestation space. There are males who produce sperm and males who produce eggs, while females contribute no gametes but carry and bear the offspring. The female dies after childbirth, and the gay couple raises the kids, no sex except reproduction though. Would be EveryoneIsGay if the couple didn't have sex with a female at one point. An alternate interpretation, one that a human character stumbles upon and considers more accurate, is that the non-sapient "females" are in fact a different species that the Puppeteers are parasitic upon--similar to the Ichneumon wasps that lay their eggs in live insects so that the wasp larvae can eat the host alive. The "sperm-producing-male" is the Puppeteer male, while the "egg-producing male" is the Puppeteer female.
* Basically every book by Billy Martin, a.k.a. Creator/PoppyZBrite. The exception would be when [[CastFullOfGay everyone is gay]].
* An astonishing number of the female characters in the ''Claudine'' stories are bi. This is shrugged off with the ignorant contemporary views of sexuality--as Claudine's husband says, "What you little animals do is charming and doesn't mean anything." It's [[DoubleStandard another matter entirely]] if a man should be interested in both sexes.
* In the novels by Gregory Maguire (especially ''Literature/{{Wicked}}''), everyone is bisexual until they state they don't care for one or both genders. (Especially if you're descended from the Thropp line.) Hell, in terms of ruining your childhood, it wouldn't be much of a stretch to pin this on the [[Literature/LandOfOz Baum Oz books]].
* In Fiona Patton's ''Literature/TalesOfTheBranionRealm'', pretty much everyone is bi, and this goes completely unremarked. There is even a Guild of Companions (a cross between bodyguard, courtesan, same-sex sexual partner, and spy) who are contracted to the nobility. The first book revolves around the Crown Prince's relationship with his mother--she wants him to get married and have an heir, he would prefer to shack up with his Companion. He starts a civil war over this. His mother, BTW, has four Companions of her own.
* In Creator/RobertAHeinlein's ''Literature/TimeEnoughForLove,'' Ishtar and Galahad agree to "Seven Hours of Ecstasy," even though they have so far seen each other only in all-concealing biohazard-protection suits and, thus, neither knows the other's sex. It is strongly implied that in their society (the Howard Families colony-world of Secundus), it is considered in bad taste even to care.
** Each one is pleasantly surprised to learn the sex of the other, as Ishtar is oddly tall and Galahad is oddly short. And both are absurdly beautiful, particularly Galahad (think the statue of David, except not terrified).
** It's also implied in ''Literature/StrangerInAStrangeLand'' that sexual bonding in the Church of All Worlds can occur between any water brothers regardless of gender, although this is done extremely subtly by Heinlein's standards.
** In ''Literature/IWillFearNoEvil'', Johann (a dying billionaire) has his brain transplanted into a new, young body and becomes Joan. With the body of a woman and the brain of a man, is his attraction towards women or men the gay one?
* An InformedAbility in the ''Franchise/DoctorWhoExpandedUniverse''. In ''All-Consuming Fire'' Benny says that bisexuality is the norm in the 25th century (although she personally isn't). Subsequent books set in Benny's home era have offered no evidence of this.
* In ''Literature/TheNeanderthalParallax'', everyone in Neanderthal society is Bi, being expected to take a "man-mate" and a "woman-mate".
* WordOfGod about the ''Literature/LiadenUniverse'' novels is that Liadens should be assumed to all be bi. We see several homosexual encounters but all the permanent arrangements we see on screen are heterosexual--unsurprising for a culture that puts huge weight on providing an heir.
** However, the ''Literature/LiadenUniverse'' novels don't feature all that many permanent partnerships. Liadens tend to contract a temporary marriage where it is agreed in advance which House will have permanent sole custody of the child to be produced.
* ''Literature/{{Swordspoint}}'' and ''The Privilege of the Sword''--perhaps not ''everyone'' is bi, but the only monosexual major characters are the villainous Lord Ferris (a depraved heterosexual, perhaps?) and [[spoiler:Marcus]], whose straightness may or may not have been caused by childhood trauma (thereby inverting RapeAndSwitch).
* Due to the nature of a dragons mating flights and the fact that over 50% of the dragon population are females that mostly take male riders, it's implied that at least 80-90% of dragonriders in Creator/AnneMcCaffrey's ''Literature/DragonridersOfPern'' series are at least bisexual. Only Gold riders (1%) and Bronzeriders (5%) are exclusively heterosexual.
* In Janet Morris' ''The High Couch of Silistra'' and sequels, while being straight seems to be the social norm, homosexual sex is apparently commonplace and completely acceptable. Estri, who begins the novel as a [[HighClassCallGirl well-woman]] has a lot of experience servicing men, but when a customer essentially forces her into lesbian sex with another well-woman, she admits to being very aroused by the experience. Chayin and Sereth, two of her primary lovers, also have sex with each other, though [[BiTheWay only off-screen]].
* In ''Literature/TheCulture'', considering that the line between species and gender is completely blurred and deconstructed, everyone just seems to go with what they like, no matter what that is. And considering that Culture humanoid citizens can change gender and move into non-humanoid bodies with multiple sexes and... Look, suffice to say that if you brought up sexual orientation to a culture citizen they'd presume you were from a very ''very'' backwards planet.
** This is reflected in their language, which does not differentiate between sexes.
** In fact, Gurgeh from ''Literature/ThePlayerOfGames'' is considered bizarre because he's straight and has never changed his sex. A friend of his also seen as weird because she spends almost all of her time as female.
* In ''Literature/TheStoneDanceOfTheChameleon'' by Ricardo Pinto, sexuality is pretty much discarded as a point of interest, where straight and gay relationships are equally common-place. The problem comes where you have the Chosen (who are the undisputed [[MasterRace "supreme race"]] so to speak) and the other races (who act as their slaves and who aren't even allowed to look at their faces). Considering that all subservient races are completely oppressed by the Chosen and horrifically bound by The Law, there tends to be a ''lot'' of sexual abuse, rape, and subjugation of both genders of those races... and some of the stuff the more sadistically-minded Chosen are into crosses the line of "torture" and becomes BrainBleach incarnate (UpToEleven). In fact, when the main character (who is a Chosen, but brought up away from their culture), finds out that another Chosen has raped his half-slave brother, said Chosen can't understand why he's so upset and is genuinely shocked that he cares so much. Nuff said.
* Creator/ArthurCClarke's novel ''Imperial Earth'' includes a line in which the protagonist's best friend is described as "aggressively normal," because he seems to have ''no'' preference between males or females--most people in the late 23rd Century go both ways but have at least a slight inclination toward one gender or the other.
* Creator/UrsulaKLeGuin's works:
** The Literature/{{Hainish}} story "Another Story or a Fisherman of the Inland Sea", introduces the traditional culture of Planet O where pretty much everyone has to be bi for a successful marriage. Marriage is not between two people but four, two men and two women--a man and woman of the Morning moiety and an Evening man and woman. The Morning woman and Evening man, the Evening woman and Morning man, the Morning woman and Evening woman, and the Morning man and Evening man all have sex with each other, meaning every partner in the marriage has a husband and wife from the opposite moiety. (Sex within the moiety is forbidden, so the Morning man/woman and Evening man/woman in the marriage are strictly platonic. In fact, it's perfectly proper for siblings to be the Morning or Evening half of the foursome. Yes, this does mean that you are banging the same woman that your sister is regularly doing, and also the man who would otherwise be your brother-in-law.) The protagonist's mother, a Terran woman of Japanese descent, married in this way to be with the man she loves but finds it strange many years into the marriage, even though she is on good terms with her wife in the marriage.
** In ''Literature/TheLeftHandOfDarkness'', the setting is a planet where the dominant species are asexual most of the time, but periodically go into heat, becoming male or female at random in each encounter (but when two people are having sex, apparently one always becomes male, one female).
* In ''Literature/{{Palimpsest}}'' it's not as much as Everyone Is Bi but "Everyone is so desperate to go back into Palimpsest that they will slept with anybody with the mark, no matter the gender".
* Many Creator/MaryRenault novels fit this trope. She wrote a lot of historical fiction set in ancient Greece, where bisexuality was considered the norm, for males at least. Some of her Greeks are exclusively or near-exclusively heterosexual or homosexual, but many aren't. The characters in her contemporary novels are also often quite flexible about gender.
* In the LyremouthChronicles series by Creator/JaneFletcher, this is the standard situation for the people on the mainland (the islanders have a more [[BuryYourGays mediaeval]] approach towards same-sex relationships), to the point where being exclusively attracted to a single sex is almost incomprehensible and rather rare. The closest the mainlanders get to homo/heterosexuality is preferring a single sex, which is put on the same level as a preference for tall people, or people with blond(e) hair.
* Most of the characters in Creator/BretEastonEllis' novels are bisexual. They are usually depicted as having sexual encounters of both kinds within the storylines. It may be a bit of WriterOnBoard.
* In ''Literature/OutlanderLeander'' by Eisah, Leander and Ellora argue which one will flirt with a Geuranian man to get information. Neither ever considers that the other man would prefer one gender or the other.
* Dorne in ''Literature/ASongOfIceAndFire'' has this reputation as its [[PlanetOfHats hat]], having a more more liberal take on homosexuality--and sexuality in general--than the rest of Westeros. However, while several Dornish nobles ''are'' openly bisexual, Martin's standard treatment of [[PlanetOfHats sweeping generalizations]] suggests this reputation is exaggerated.
* About half the cast of ''Literature/ThePictureOfDorianGray'' is bi. Then again, it was written by Creator/OscarWilde.
* In Daniel Handler's ''Adverbs'', the narrator states that everyone is bi. Many otherwise straight male characters have sex and/or fall in love with other male characters.
* In Joan Slonczewki's ''Elysium'' novels, everyone is bi in the FreeLoveFuture. In ''Brain Plague'', one male character only dates women, "his obsession medieval." He does get into a relationship with another man but asks him to become a woman.
* In Creator/SamuelRDelany's ''Triton'', not everyone is bi but most people are. The plurality sexuality for females is male-oriented bisexual and males are most often female-oriented bisexuals.
* In ''Literature/ThePardonersTale'' Alex is openly bisexual with no clear preference for either gender.
* Strongly hinted to be the future of human society in the Creator/NeilGaiman short story "Changes". After all, when it's possible to [[GenderBender completely change to the opposite biological sex]] right down to the genetic level by [[EasySexChange popping a pill and waiting a few hours]] the whole question of sexual orientation and indeed gender identity becomes somewhat academic.
* Blink and you miss it, but it's implied in the ''[[Literature/MalazanBookOfTheFallen Malazan]]'' prequel ''Literature/TheKharkanasTrilogy''. It seems to be the norm that among the Tiste people, marriage happens between opposite sex partners in order to produce children, but outside of marriage no one seems to bat an eye at whoever anyone is sleeping with and several point of view characters are shown to be attracted to people of both genders.
* In ''Literature/LionsOfAlRassan'' by Creator/GuyGavirelKay, all ''men'' seem to be at least AmbiguouslyBi. Could be a subversion as it seems to be culturally expected (in universe) of men, especially nobles or royals, to be into AnythingThatMoves.
* In ''Literature/TheMachineriesOfEmpire'', everybody seems to be pansexual, though it's hard to tell, given how little attention anyone is paying to things like sexual orientation.
* In the ''Literature/ImperialRadch'' series, the Empire of the Radch has no societal concept of gender, and one Radchaai expresses confusion at how the specific kind of genitalia people have is such SeriousBusiness in some cultures. If anyone in the series is particular about their partner's sexual characteristics, it goes unmentioned.
* In Tansy Rayner Roberts's ''Literature/MusketeerSpace'' (''Literature/TheThreeMusketeers'' gender-flipped IN SPACE) assume everyone is bisexual unless specified otherwise - Aramis only likes girls and Porthos is the only straight character in the book.

[[folder:Live Action TV]]
* In ''Series/{{Torchwood}}'', everyone in the main cast is at the very least bi-curious. The ''Series/DoctorWho'' episode that introduces Jack Harkness states that his omnisexuality is common for the century (51st) that he grew up in, in which the [[Franchise/StarTrek Captain Kirk]] [[BoldlyComing approach to first contact]] has been the norm for so long that species and gender lines have become muddled. As Creator/StevenMoffat explains, it's a future where the whole human race is pansexual. Of the Torchwood gang, Tosh and Owen are properly bisexual, Ianto is either just [[IfItsYouItsOkay bi for Jack]] or lying about not being into men who are not Jack, Suzie is seen snogging Gwen, and Gwen doesn't elaborate on which aspect of being kissed by various female villains weirds her out. (WordOfGod has confirmed that Gwen is also bisexual).
** A flashback involving two female members of Torchwood 3 in the 19th century (Alice and Emily) shows that they are a lesbian couple. At least one of them may be bi, given that she finds Jack to be pretty, but that may simply require the possession of sight.
** You can probably just safely assume that everyone in a Creator/RussellTDavies show is bisexual unless explicitly stated otherwise. Davies has explicitly stated that he doesn't really believe in rigid definitions of sexuality, and that all self-identified straight people have at least minor gay tendencies and vice versa. Creator/StevenMoffat uses this trope a fair amount, too, though not as much as Davies.
** PlayedForLaughs in "[[Recap/DoctorWhoS36E10TheEatersOfLight The Eaters of Light]]". The ancient Romans consider 2017 native Bill Potts's lesbianism to be rather old-fashioned. NotThatTheresAnythingWrongWithThat, it's just that normal people like both instead of restricting themselves like that, that's all. Bill is suitably confused.
* ''Series/TheDailyShow''. ''Everybody'' on the show has either shown bisexual tendencies on screen, or simply mentioned having had sex with both genders.
** More often than not, the bisexuality is played as either comedic misunderstanding themed (Jason Jones once mentions that he married a gay man, after misinterpreting a recent ruling allowing gay marriage) or the correspondent is gay for pay (as seen with Rob Riggle, who had sex with men for money in order to earn the cash to buy an iPhone.)
* Creator/JMichaelStraczynski's philosophy for ''Series/BabylonFive'' was that in 2258, sexual orientation is a non-issue--not that everyone is bi, people just don't make a point of it. He suggested early on that one of the main characters was bisexual. This turned out to be Ivanova, but it only came up a couple of times.
** Another interesting note is in the Babylon 5 movie ''River of Souls'' we find out that a holographic program was created with an image of Captain Lochley. Garibaldi discovers this program is especially popular with women.
*** It's never established whether Lochley's relationship with her late friend Zoe (temporarily resurrected in "Day of the Dead") was a sexual one, especially since they spent her one night alive just talking. On the other hand, it turns out that Lochley has missed her enough to be using "Zoe's Dead" as her ''computer password'' twenty years later.
** In a subtler incidence, Marcus and Franklin pose as a newlywed gay couple when undercover on Mars. Nobody considers this unusual, though people aware that it's a cover do consider it funny--not the idea that they might be gay, but because they make such an ill-suited couple.
* WordOfGod for ''Series/BattlestarGalactica2003'' is that all Cylons are Bi. This is actually seen in the Three and Six models.
* ''Series/SexAndTheCity'': In the episode "Boy, Girl, Boy, Girl...", Carrie dates a man who later reveals himself to be bisexual. In the last scene, Carrie meets his group of friends at a party and discovers nearly all of them have dated each other at some point, with gender apparently being a non-issue, though there is one effeminate man they refer to as their "token straight" friend.
* In ''Series/{{Farscape}}'', sexuality is completely by-passed as an issue. When you have trans-alien relationships, the actual gender of who you're attracted to becomes moot. It's also implied that humans are comparatively very rigid and backward when it comes to sexuality. Both D'Argo and Chiana seem surprised that humans generally start having sex so late (D'Argo first had sex when he was... seven, Chiana's just confused that they dress provocatively if they're considered underage), and Aeryn illustrates how in the Peacekeepers sex is fine as long as it doesn't involve any emotions. Chiana at least certainly doesn't make any distinction...
** If you count dreams, fantasies, illusions, and mind probes, Crichton had sex with every single member of the crew, including a BDSM fivesome with Rygel. Part of the point of all of these incidents is that even if Crichton never acted on them, he certainly ''thought'' about sex with all his crew members.
** One particularly amusing episode featured an alien who, after being annoying comic relief for 47 minutes, closed out the show by coming on to D'Argo. Up to that point, D'Argo and the viewers had assumed the alien was male (the role was filled by a male actor), but she assures everyone that she is, in fact, female and "Quite the looker." It's not clear whether D'Argo is more turned off by her masculine (by everyone else's standards) appearance or just by her personality. At episode's end, Chrichton checks to make sure that Aeryn is in fact "The female of her species," (although he was probably just joking). It's hard to say where this episode puts the cast in terms of this trope, except to demonstrate just how weird and unpredictable ideas like sexual identity and gender roles become in a cross-species environment. If everyone isn't bi, they might as well be, because all terms and definitions are more or less out the window.
** Chiana is quite obviously AnythingThatMoves but there are plenty of comments by/about D'Argo in particular that reveal he just might go both ways as well. The two that come immediately to mind are when Chiana proposes that Crichton have sex to get over his writer's block and when asked with whom, Chiana replies "Me, him, whoever", referring to D'Argo. Also, in the episode when John gets married and asks D'Argo to be his best man, D'Argo replies "I'm with Chiana now, John", the implication being that he'd be perfectly willing to be John's ''best man'' if he was single.
* ''Series/NipTuck'': Several of the characters have been bisexual and several of the heterosexual men have been raped by other men. Julia becomes a lesbian in season 4 but goes back to her usual two men, Christian and later Sean. Liz, a staunch lesbian, relaxes her standards for Christian. Matt falls in love with Ava, almost gets compelled to do gay porn to pay for his meth habit, and briefly becomes a prison wife in the final season before reuniting with Ava. Merril Bobolit becomes Escobar Gallardo's prison bitch. Gina is seen to have had sex with several men and one woman in one episode. Kimber as a porn star frequently slept with women for work, and frequently had threesomes to make Christian happy. Quentin Costa is a bisexual intersex rapist. Christian briefly had gay dreams about his best friend/business partner Sean.
* ''Series/TheMightyBoosh'': Ended up like this by season 3 for the most part, if the character wasn't gay. Virtually every minor or major character mistook Vince for a woman and hit on him, and didn't seem put off when he turned out to be a man. Male villains fell for Howard as well, notably the Hitcher, who only wanted to rape women before him. In season one, Howard's female crush showed lots of interest in Vince, but her last appearance saw her falling in love with a female panda, who had previously been on a date with Vince and had an abusive panda ex-boyfriend. Vince himself is AmbiguouslyBi.
* ''Series/ATouchOfCloth'', thanks to RuleOfFunny and the StylisticSuck of the 'writers' ignoring characters' sexualities when it suits them. Ann Oldman is a lesbian but her main love interest is Jack, Jack mostly has female sexual partners but inexplicably hooks up with Tom Boss at the end of Part II, and the HoYay is omnidirectional.
* ''Series/ItsAlwaysSunnyInPhiladelphia'' co-writer Glenn Howerton said he sees every main character this way, except Mac, who is gay.
* ''Series/BlackSails'' qualifies for this trope. Most of the characters that are shown in romantic/sexual relationships have them with both genders--Eleanor, Max, [[spoiler:Anne Bonny and Captain Flint]]. It's not majorly remarked upon either.
* On ''Series/{{Hannibal}}'' it would be far easier to list the major characters who haven't shown some sign of sexual fluidity or outright gone for both sexes. Hero Will Graham and the title character long had a romantic subtext that eventually became text. Alana Bloom had an affair with Hannibal before marrying Margot Verger, who had previously seduced Will for a baby. Jack Crawford would seem to have SingleTargetSexuality for his dying wife, but even he seems to be charmed by Hannibal on some level.
* In the future world of ''Series/TheExpanse'', a significant fraction of humanity appears to identify as pansexual.
* ''Series/{{Westworld}}'': The robotic Hosts in the park don't have sexual orientation in the way humans do, but all are programmed to not be picky in regards to gender so that they can be seduced by any guest. This is most clearly seen in the saloon, where the prostitutes there proposition all guests that enter, regardless of gender.
* ''Series/LostGirl'': The main character, Bo, is a succubus that "feeds" off sex. She never has any problem finding"food" as virtually everyone she meets, male or female, is attracted to her. Frequently, characters who have previously been implied to be exclusively heterosexual suddenly have sex with the same gender without any previous indication of them being attracted to that gender.

* "Swings Both Ways", a tongue-in-cheek duet between Robbie Williams and Music/RufusWainwright, claims that everyone in Hollywood at least acts like this to get the most lucrative business deals.
* Music/{{Blur}}'s "Girls and Boys".

[[folder:Tabletop Games]]
* ''TabletopGame/MaidRPG'' includes seduction rules that are specifically mentioned as "not in any way governed by gender."
* ''TabletopGame/BlissStage'', as the trope namer for LevelUpAtIntimacy5, tends to have a lot of this.
* In ''TabletopGame/ChangelingTheDreaming'', bisexuality is extremely common among the Kithain, and their society is extremely tolerant of the idea. This is mainly because fae souls keep {{reincarnati|on}}ng throughout history, most changelings have changed genders between incarnations at least once, and [[ReincarnationRomance true love that defies the tides of time]] is pretty much a proven fact in their society.
* ''TableTopGame/TwilightSparklesSecretShipficFolder'' is a game about {{Shipping}}, so ubiquitous bisexuality helps keep the options open.

[[folder:Video Games]]
* ''VideoGame/TheSims'': For simplicity's sake, every Sim can romance any other Sim, at least as far as gender goes. There are some obstacles, but none of these are gender.
** The ExpansionPack ''VideoGame/TheSims2: Nightlife'' complicates things: positive romantic interactions increase a Sim's invisible attraction score to that gender, allowing better chemistry. Gender preference can also decay, so if your [[AnythingThatMoves Romance Sim]] flirts with male Sims all the time, they can suddenly stop being attracted to female Sims. Pretty weird, even for a game like ''The Sims''. Whereas if they flirt with both they will be attracted to both.
** The issue with ''The Sims'' was that a Sim would flirt with everyone. They changed it in ''2'' so that while a Sim would be amenable to sex with either sex, they would only autonomously have one preferred sex, defaulting to heterosexual but homosexual if the user chose to play them that way.
*** In ''The Sims 2'', Sims are asexual by default until a romantic interaction is performed by or on them.
** In ''The Sims 3'', inactive sims default to heterosexual unless the active sim performs a homosexual interaction with them. This can then result in [[{{Gayborhood}} an entire town of gay people.]]
* The [[GreenSkinnedSpaceBabe asari]] in ''Franchise/MassEffect'' are a OneGenderRace of blue women who can breed with anyone (any species, any gender). Needless to say, many asari appear to be bisexual, because they seek people to mate with based on different criteria (with a focus on species, not gender). A few side conversations suggest they don't fully understand the concepts of gender and orientation; for instance, an asari's father is the parent who didn't give birth even if both are asari.
** While the asari are noted to be extremely attractive by just about everyone, and it's implied that IfItsYouItsOkay is in effect for some of their partners, this is [[AvertedTrope averted]] in regards to other species partnered with asari. A straight human female character in ''VideoGame/MassEffectAndromeda'' notes that she's not interested in women and turned down advances from her asari colleagues while serving in their military.
* In the [[TastesLikeDiabetes unbearably cutesy]] ''VideoGame/AnimalCrossing'' clone ''VideoGame/MagiciansQuestMysteriousTimes'', any classmate can be romanced by either gender, which likely earned it its E10+ rating.
* ''VideoGame/WorldOfWarcraft'':
** One of the succubus's abilities, Seduce, can affect males and females equally.
** Similarly, each version of the Theramore's Fall scenario has a male enemy that using a stun ability called "Dashing Smile", which affects players of either gender.
** During the Valentine's day event, [[PlayerCharacter PCs]] can exchange pledges of adoration with [[NonPlayerCharacter NPCs]] for love tokens. Gender is only a factor in that female [[NonPlayerCharacter NPCs]] will romance [[PlayerCharacter PCs]] wearing cologne and male [[NonPlayerCharacter NPCs]] will romance [[PlayerCharacter PCs]] wearing perfume. Either gender can wear either cologne or perfume. Worth mentioning that to get the Largest prize you need at least twenty pledges from each city, Darnassus is all female and Ironforge is all male. On Horde-side, Silvermoon is all male.
* In ''VideoGame/CityOfVillains'', Succubi have a power called "Come Hither" that prevents players from being able to attack them directly. Interestingly, it works on both genders just as easily. The spell is broken immediately if the Succubus attacks the player.
* Quite possibly the men of ''Franchise/MetalGear'', where there are three canon bisexual characters--Colonel Volgin, Vamp, and Dolph himself. There's also [[HoYay subtext]] between Solid Snake and Otacon despite their own things for the ladies, and while Big Boss has no canonical partner he benefits from [[EvenTheGuysWantHim Everyone Being Gay For Big Boss]] with [[spoiler:EVA/Big Mama]] and especially when [[spoiler:Ocelot goes so far as to sacrifice his own personality/self by using nanomachines and hypnotherapy to make himself think that he was Liquid Snake]]--hence "Liquid Ocelot"--throughout the events of ''VideoGame/MetalGearSolid4''... all for the cause, all for Big Boss.
** In ''Metal Gear Online'', both male and female characters can learn the Charm ability which causes them to do a sexy dance, stopping other characters in their tracks. The sexy dance does not discriminate based on gender.
*** Neither do the play-boy magazines
** Big Boss can also go on a date with Miller at the end of Peace Walker and take photos of him on the beach in a thong.
*** That they have sex afterwards may also be relevant.
** Dr. Strangelove, she has a took a liking for Otacons dad, and she was totally into The Boss, much like Ocelot is to Big Boss.
* In the main ''Franchise/{{Pokemon}}'' games, "Attract" only works on Pokémon of the opposite gender, but in ''VideoGame/PokemonMysteryDungeonRescueTeam Red and Blue'', where only the player character has a definite gender, Attract works on (virtually) everyone. While "Attract" affects only the opposite gender in the main series, the same cannot be said to "Charm" and "Sweet Kiss", though the earlier might apply to the Pokémon's cuteness.
* Parodying the RomanceSidequest, all of your homies in ''VideoGame/SaintsRowIV'' can be "[[IsThatWhatTheyreCallingItNow romanced]]" with a single button press, regardless of your character's gender. And yes, ''all'' of them. In the same playthrough. As many times as you want. Even CID, the [[{{Robosexual}} spherical floating robot]]. But not Creator/KeithDavid, who just wants to keep things professional. Pierce is notable in that no matter which gender you are, he'll tell you he [[IfItsYouItsOkay doesn't normally swing that way]]. Also, romancing Ben King gives the longest cutscene, in which the Boss seemingly wants to confess his/her feelings for King but CannotSpitItOut, to which King reassures him/her that he already knows what he/she wants to say and that he wants him/her to say it, as the [[BowChickaWowWow porno music]] builds. [[spoiler:[[BaitAndSwitch The Boss just wants him to sign his/her copy of his book]]]].
* ''Franchise/TheElderScrolls''
** In ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', if you get Personality stat high enough, [=NPCs=] of either gender, ''everywhere'' that you go, will greet you with the phrase "I like what I see" or something similar. This is, of course, regardless of which gender (or even race) the PC is. Additionally, the response to many of the "Admire" [[CharmPerson persuasion options]] appears to be a response to a come-on or pickup line, once again regardless of the player character's gender (or race).
** In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', which adds marriage as an option for the first time in the series, ''every'' marriageable NPC can be married by the player character, once again regardless of the player character's gender or race. Seems to be a bit of a case of GameplayAndStorySegregation though, as in-universe gay couples not involving player characters are extremely rare, though there still doesn't seem to be any prejudice against them. Of course, this gets {{Lampshaded}} by MetaGuy and FourthWallObserver M'aiq the Liar:
-->''"The people of Skyrim are more open-minded about certain things than people in other places."''
* Downplayed in ''VideoGame/VampireTheMasqueradeBloodlines'': most women who can be seduced are available irrespective of the player character's gender, though male [=NPCs=] are more likely to be heterosexual.
* In ''VideoGame/{{Cupid}}'', you can match up anyone with anyone.
* ''VideoGame/LiberalCrimeSquad'' allows you to seduce people of any gender (and you often don't know their gender before you try to seduce them). The chance of success depends solely on your skills.
* In ''VideoGame/StarOceanTheSecondStory'', any of the characters in the party can have [[RelationshipValues romantic feelings]] for any of the other characters, regardless of gender (or age, or marital status.)
* In ''VideoGame/FallenLondon'', there are storylines that allow the player to romance partners of any and every gender...including at least two threesomes. In fact, the text is always written so the PC's gender never makes a difference; "the Dashing Smuggler slips his arm around your waist", for example. (It helps that the PC's gender can be set as "Gentleman", "Lady" or "There are people walking around with the faces of squid — ''squid'' — and you have the nerve to ask me my gender?".)
* In ''VideoGame/DragonAgeII'', all the main romance options are available to both genders (appropriately, one of them is voiced by Eve Myles from ''Torchwood''). DLC character Sebastian is the only heterosexual-only romance, as well as being celibate.
** And even Sebastian is implied to have had encounters with men as well as women before he took his Chantry vows, which prohibit sexual relationships.
** Several of the non-romanceable companions are also implied to have bisexual tendencies to varying degrees. Aveline can kiss Hawke regardless of gender at the end of her Act 2 loyalty mission, Bethany expresses some curiosity about Isabela's sexual history with other women and Varric has some slightly flirty dialogue with Anders ([[CargoShip though his heart belongs to Bianca, his crossbow]]). Even Bianca apparently feels some "confusion" when Isabela suggests she needs "a woman's touch on her trigger."
** The nation of Orlais takes this trope UpToEleven with the nobility. Because sleeping your way to the top is basically a necessity to play [[DeadlyDecadentCourt the Grand Game]], and since there's no significant stigma against homosexuality in Thedas, it's a well known fact that most Orlesian nobles will bed anyone, male or female, to climb the social ladder, regardless of their actual orientation.
** The other games in the series avert this trope, with exclusively gay and straight potential romance partners mixed in.
* In ''VisualNovel/MagicalDiary'' not only can the PC date both male and female options, but many [=NPCs=] have explicitly dated both, and no one raises an eyebrow. [[WordOfGod Hanako has also confirmed that this game is running on this assumption.]]
* In ''VideoGame/GuildWars2'', the Sylvari are noted to be like this. They're a race of plants mimicking the humanoid form, are incapable of sexual reproduction, and socially have no concept of gender. Developer blogs about Sylvari society and culture have noted that Sylvari consider gender completely irrelevant, including in matters of love.
* In ''VideoGame/DragonsDogma'', you can end up with anyone. Whether it's a male or female Arisen, you can have male on male and female on female. Some scenes ''don't even change'' regardless of gender, and this will cause some characters to come across as this.
* In ''VideoGame/{{Borderlands 2}}'', any character that shows some attraction to the [[PlayerCharacter Vault Hunter]] will do so regardless of the Vault Hunter's gender, several gay relationships are mentioned in passing, and virtually everyone in Sanctuary has some interest in [[MsFanservice Mad Moxxi]]. Although this seems to be because the game didn't have any way of detecting which character you were playing as at all. The following game, ''VideoGame/BorderlandsThePreSequel'', ''could'' detect this, and as a result has more characters that are explicitly attracted to only one gender and even specific characters. Janey Springs for example crushes hard on Athena but says Nisha isn't her type, and isn't into men at all (though she does admire [[BadassBeard Wilhelm's beard]]).
* In ''VideoGame/SpaceColony'', it is possible for any two colonists to become romantically involved.
* In ''VideoGame/HighSchoolStory'', you can pair up ''any'' two students and send them on a date. This includes [=NPCs=] who may canonically have a straight crush.
* ''VideoGame/HuniePop'' includes a setting for whether the PlayerCharacter is male or female. None of the girls you romance react any differently, and [[LoveFreak Kyu]] will express her...''appreciation'' of the girls the PC dates. Although it's implied that most of them are just attracted to whatever sex the protagonist is and the only truly bisexual characters are Kyu, Jessie, and probably Venus.
* In ''VideoGame/{{Elona}}'', you can marry and have a child with almost any NPC, regardless of sex or species. In fact, the only effect gender has in the game is [[spoiler:determining which form your pets will take when they evolve]].
* ''VideoGame/WorldsDawn'' asks the player their gender preference at the start of the game, which determines whether bachelors, bachelorettes, or both are going to be interested in you. Given that the {{Gay Option}}s are one of the things most often mentioned in reviews, it's likely that this is the norm and the mayor simply tells the other townspeople to not hit on you if you say you're only interested in one gender.
* ''VideoGame/{{Fallout 4}}:'' Most of the human (or near equivalent) companions can be romanced if you get their RelationshipValues high enough, and the Sole Survivor's gender is irrelevant.
* ''VideoGame/StardewValley'' features six bachelors and six bachelorettes you can romance and marry, regardless of the gender of your player character. Though it's quite played with, as many of them are shipped with an opposite-sex partner if you don't pursue them romantically, and pursuing a same-sex relationship with one will usually cause them to note that [[IfItsYouItsOkay they've never felt this way about another guy/girl before]]. The one exception is Leah, whose ex Kel will be brought up, and eventually show up, if you reach the romance stage with her. Kel will be the same gender as the player character, retroactively establishing Leah as whichever sexual orientation is needed.
* ''VideoGame/CrushCrush'': While only Fumi and Pamu specifically mention an interest in women, all of the girls will date you regardless of whether you're playing as a male or female character.
* In the original ''VideoGame/AvatarHigh'', any student could date any other. Its sequel ''Avatar University'' changed this so that characters have specific sexualities.
* In ''VideoGame/Va11HallA'', Glitch City is particularly accepting of different sexualities for a {{Cyberpunk}} {{Dystopia}}, and Jill serves and encounters a lot of people who run the full spectrum of humanoid sexuality, from Alma, who is strictly hetero; to Dorothy, who services both men and women in her work as a {{Sexbot}}; to Mario and Betty, who are gay. Jill, herself, is bisexual, having had a slew of relationships with other men throughout high school and a very serious relationship with a lesbian in college. This acceptance isn't uniform, however; Jill's old girlfriend was disowned by her mother because her peers were homophobic.
* ''VideoGame/AssassinsCreedOdyssey'': all romance options are available to the player regardless of whether they're playing as [[PlayerCharacter Alexios or Kassandra]]. Given that the game takes place in AncientGreece, it's probably as {{Justified}} as this trope will ever be.

[[folder:Visual Novels]]
* ''VisualNovel/FateStayNight'' [[Franchise/NasuVerse and its many spinoffs]] may or may not count, as several characters have been [[WordOfGay officially confirmed by the creators]] to be bisexual or explicitly stated so themselves in-universe. It makes sense on the Servants’ part, as most of them are from eras and cultures with very different views on sexuality and same-sex relationships than today. Non-servant characters are also subjected to having both canon opposite- and same-sex attractions or huge amounts of HoYay and LesYay.
* ''VisualNovel/LittleBusters'' has both [[HoYay subtext]] and ''outright text'' for both same-sex and different-sex attraction from a lot of characters, the protagonist included (even if the game only has het romance routes). For a bonus, both Riki and Komari either seem to be or outright are attracted to both Natsume siblings.
* ''VisualNovel/MonsterProm'': All four playable characters(two guys and two girls) are able to date all 6 available romantic interests(three guys and three girls). Even among the rest of the cast and secondary characters, it's made no distinction of gender and pretty much everyone goes for everything.

%%* ''[[http://isukiyomi.comicgenesis.com Michiko Monogatari]]''
* By this time, pretty much everyone in ''Webcomic/{{Shortpacked}}'' has had both a gay and straight experience with the exceptions of the boss Galasso and Ronald Reagan. Faz even refers to the Kinsey scale, albeit incorrectly ("Now, if I have sex with a woman, I will be a 3!").
* Most of the cast in ''Webcomic/SparklingGenerationValkyrieYuuki'' have shown or talked about attraction to both genders. The rest aren't confirmed as either bisexuals or monosexuals as of yet. Of course, most of the cast are [[Myth/NorseMythology Norse mythological figures]], where this trope also applies.
* Bisexuality is the norm for the drow in ''Webcomic/{{Drowtales}}'', with purely heterosexual and homosexual people as minorities.
* ''Webcomic/ElGoonishShive'' is a funny case, since characters who have been genderbent by Tedd's TF Gun develop a temporary attraction to the opposite gender. Depending on how you look at it, between one and two characters are naturally bisexual (Ellen is an OppositeSexClone who has all the memories of her original male self, as well as those of a heterosexual alternate self from another universe, and is only just coming to understand that she's a bisexual homoromantic. Grace is [[SingleTargetSexuality "Teddsexual"]] regardless of Tedd's current gender.), but seven of them have been genderbent, and of those the four straight ones have all had to deal with attraction to both genders. (Justin and Nanase are exempt from this due to being naturally gay--when genderbent, they just get ''even more'' attracted to guys and girls, respectively.) And it turns out the straight ones aren't exactly straight--Sarah has recently started considering herself "A Kinsey 2 ''at most''", and [[spoiler:Elliott is starting to realise that the way he feels about guys when he turns into a girl has actually not got much to do with turning into a girl.]] It's unclear whether repeated transformations alter a person's sexuality and/or gender identity, or if it just allows them to realize feelings that were already there but unexplored.
* While only two characters in ''Webcomic/GhastlysGhastlyComic'' have ever been called "bisexual", almost every cast member has slept with, kissed, or had a StupidSexyFlanders moment with members of both sexes at one point or another.
* WordOfGod for ''Webcomic/TheChallengesOfZona'' is that [[ProudWarriorRaceGuy the Erogenians]] practice "situational bisexuality" as a matter of course and that Zona and Tula have had lovers of both sexes.
* Most, if not all webcomics by Creator/GiseleLagace tend to have this. Justified in that SexComedy is her bread and butter. More possible pairings = more possible jokes.
** ''Webcomic/MenageA3'' starts out with a varied cast of gay and straight guys/girls with one bi girl. By now, every single named character (and plenty of one-off extras) has had at least two or three instances where they've shown more than a little attraction for both genders, with the exception of the landlady, the guy who stays indoors and thinks it's still the 80's, and the ''extremely'' CampGay Dillon.
*** {{Lampshade|Hanging}}d by Zii (the aforementioned bi girl) when she calls up Dillon, asking to be taught the kissing technique he previously taught Gary, which just so happened to give spectacular results when used for cunnilingus and turned Gary into an in-universe MemeticSexGod. She phrases her request... poorly.
---->'''Dillon:''' You want ''me'' to teach you how to go down on a woman?\\
'''Zii:''' ''[hanging up]'' That was a dumb idea. Why can't he be bi like the rest of us?
** Pretty much the entire cast of ''Webcomic/MagickChicks'' has shown that they wouldn't turn down either sex, though Faith's abilities make some of them ambiguous.
* ''Webcomic/{{Homestuck}}'': Alternian culture is binormative. Trolls reproduce rather like social insects and do not form families, so gender is pretty much cosmetic. Their emotional lives center around ''4'' types of romantic relationships, 2 of which are usually sexual. While monosexual trolls exist (like lesbian Kanaya), their language lacks words for orientation; Karkat is nonplussed when the human characters try to explain the concept to him.
-->'''Karkat''' [[NoIndoorVoice HUMANS HAVE A WORD FOR THAT?]]\\
'''John''' yes.\\
'''Karkat''' HOW IS THAT EVEN A THING?\\
'''John''' shrug. it just is.\\
* In ''Webcomic/{{Curvy}}'' everyone seems capable of making out and having sex with virtually anyone else, on a moment's notice.
* In ''Webcomic/{{UC}}'', only Nicodemus is [[http://www.wanderingchaos.com/uc/100305.html confirmed]], in comic, to have dated both genders, but [[http://littlestyo.deviantart.com/art/I-am-a-yaoi-FIEND-10044216 author]] [[http://littlestyo.deviantart.com/art/Naim-Kelsi-Cuteness-34910638?qo=14&q=by%3Alittlestyo+sort%3Atime+-in%3Ascraps created]] [[http://littlestyo.deviantart.com/art/Ikku-Kelsi-cuteness-20355133 art]] [[http://littlestyo.deviantart.com/art/Naim-and-Kelsi-cuddly-chibis-11669296 suggests]] that the rest of cast is also bi.
* Due in part to AuthorAppeal, [[Webcomic/ScandinaviaAndTheWorld most]] [[Webcomic/{{Niels}} comics]] [[Webcomic/ManalaNextDoor of]] Creator/{{Humon}}'s portray a high number of Bi characters. Of note is ''Webcomic/{{Niels}}'', where about 80 percent of the protagonists are queer in some way, particularly the title character.
* Almost everyone in ''Webcomic/{{Oglaf}}'', whether due to RuleOfFunny or RuleOfSexy. Notable exceptions are Ivan, who [[IncompatibleOrientation keeps getting hit on anyway]] by a DepravedHomosexual, and Kronar's tribe of butch gay {{He Man Woman Hater}}s.
* In ''Webcomic/TheGlassScientists'', WordOfGod has it that all characters are bisexual, with exception of ''pan''sexual Jekyll/Hyde. The whole main cast is bisexual, though with varying degrees of awareness of their sexuality, and the Lodgers at Jekyll's Society for Arcane Science are all up for grabs sexuality wise. Most likely very few of them are straight.
* ''Webcomic/ZebraGirl'': Dream!Sam (a figment of Sandra's imagination) says that everyone is this to some extent. It comes up when Sandra asks why Dream!Crystal is trying to seduce her, and Sam says that [[spoiler:Incubus]] created her by reading Sandra's memories and found Sandra's clandestine feelings for her.
* In [[http://thepunchlineismachismo.com/archives/comic/five-years-of-mgdmt this]] ''WebComic/ManlyGuysDoingManlyThings'' comic, [[Film/MadMax Max]] freaks out when he realizes he's the only one at the barbecue that ''isn't'' bisexual. Later strips expand on this, revealing a good number of characters (but not everyone) have had romantic relationships with both sexes. [[http://thepunchlineismachismo.com/archives/comic/you-all-knew-i-had-to-make-a-comic-about-the-hot-dad-dating-sim Commander is afraid]] after stumbling into a meeting of attractive single fathers that he might settle down again even though he's terrible at it.
--> "Anyone else surprised to hear that come out of someone dressed that much like a [[ManlyGay Rob Halford]] body-double?"
* WordOfGod confirms that all characters in ''Webcomic/SaintForRent'' are some level of bisexual, unless they're {{asexual}}.

[[folder:Web Original]]
%%* ''AudioPlay/DirtyPotter''
* Applies to all the male characters of ''WebVideo/YuGiOhTheAbridgedSeries'' with the exception of Pegasus, who is {{Armored Closet|Gay}} [[CampStraight Straight]].
* Almost everyone on Website/ThatGuyWithTheGlasses will flirt or perv on a person of their own gender if it aids a joke or {{fanservice}}. Or in the case of WebVideo/DemoReel, pure AuthorAppeal. The reboot of WebVideo/TheNostalgiaCritic {{Lampshaded}} that all the (in-universe) characters are fluid when it comes to gender and sexuality.
* Website/GaiaOnline's Valentines 2009 event allowed the users to send Valentines to a number of [=NPCs=], who would respond or refuse according to programmed turn-ons or turn-offs. [[TheCasanova Liam]], [[PetHomosexual Devin]], and [[GagBoobs Vanessa]] refused Valentines based on the sex of the avatar who sent it to them; everyone else had qualifications based on other things and would respond regardless of gender.
** In addition, there have been three Chance Item sets based on {{Dating Sim}}s. The user can freely choose whether to pursue a male or female love interest in each, and none of the interests are restricted by the user's gender.
* In the UsefulNotes/FurryFandom many characters and members of the fandom seem to have sex with either gender. There have been repeated surveys of the fans and usually bisexuals make up 40-60% of the group. This is at least in part because LBGT people find the acceptance and openness of the community to be an attractive social group, and get into the furry aspects after joining.

[[folder:Western Animation]]
* ''WesternAnimation/DrawnTogether'': Every cast member seems to have slept with or kissed at least one other character of the same sex.
* ''WesternAnimation/SouthPark'': The episode "Two Guys Naked in a Hot Tub" uses a variation on this as an Aesop when Randy and Gerald masturbate in front of each other in a hot tub. This culminates in almost all of the then-current male adult male townspeople admitting to having masturbated in front of another male, declaring that "everyone's a little bit gay".
** Several episodes use this for RuleOfFunny purposes as well, with many male characters being depicted with attractions to both sexes in multiple episodes despite being identified as strictly heterosexual or homosexual, including Cartman, Craig, Mr. Garrison, Jimbo, Stan's Dad, Butters' Dad, Priest Maxi, and Detective Yates.
* ''WesternAnimation/TheSimpsons'': Male cast members will often show attraction to other men. Especially if it's [[RuleOfFunny funny]]. ([[StupidSexyFlanders "It feels like I'm wearing nothing at all. Nothing at all. Nothing at all!"]])
* ''WesternAnimation/{{Superjail}}'': Maybe? It's not even entirely clear about the ''gender'' of the collective main cast. In any case, no one seems to be deterred in their crushes by little things like transsexuality or gender-switched counterparts from another planet/dimension or people who can apparently spontaneously give birth through their anuses. Or ''death''.
* ''WesternAnimation/FamilyGuy'': Almost every main character has had a bisexual experience. Peter had sex with President Bill Clinton, Lois had a girlfriend in college, Meg briefly dated another girl, Chris kissed and developed a crush on a girl while believing her to be a boy, and Stewie's sexual orientation seems to be [[RuleOfFunny whatever the current joke calls for]].
* In ''WesternAnimation/{{Archer}}'', nobody on the show sees anything wrong with sleeping with someone of your own gender. In one bizarre variation of the Trope, Lana seduces Ray, a man who is openly gay. (No one is ''that'' gay," he claims.)
* WordOfGay from one of the storyboard artists for ''WesternAnimation/StarVsTheForcesOfEvil'', Sabrina Cotugno, claimed this [[FlipFlopOfGod in response]] to another storyboard artist, Kristen Gish, trying to pull GodDoesNotOwnThisWorld on the characters' sexual orientations. Incidentally, Cotugno also happens to be the creator of ''WebComic/TheGlassScientists'' mentioned above.
