The homosexual version (and logical conclusion) of I'm a Man, I Can't Help It, All Men Are Perverts, and A Man Is Always Eager. If all men constantly want sex, then men attracted to other men obviously must be constantly having sex.
Alan is gay. Alan loves Bob. Bob may or may not be gay (or bi) and may or may not eventually partner with Alan; the story needs more time to bring that out one way or the other.
Alan, meanwhile, happens across a good-looking guy; blushes; and, within the space of a night, is picking up his clothes from the guy's floor. He may then go on to do as much with half a dozen more guys before the story gets around to answering whether or not he can hook up with Bob.
If this were a heterosexual relationship that we're talking about, it would clearly say something about the character of Alan as an individual (can't keep his pants up, even while waiting for his "love" to accept him...let's not even talk about how this would look if Alan were Alice instead).
There are certainly celibate characters who have heterosexual urges that they choose to control. Gay characters who choose to be celibate for any significant length of time are almost unheard of. If they're celibate, it's because they can't find a mate, or because they are forced into an abnormal situation.
This trope has some interesting historical basis, in that many gay and lesbian writers post-Stonewall (and a few queer theory writers more recently) advocated emphasizing difference from heterosexual and normative life. This difference included denigrating marriage and monogamy, thus strengthening the link between homosexuality and promiscuity in the eyes of those who viewed all homosexuals as sick sexual deviants.
How this trope is treated in the eye of the writer (or the reader for that matter) will depend on how they view sexuality itself, whether they believe that frequent sex when detached from romantic relationships is a matter of morality, and what they believe normative sexuality should be.
Possibly both of the characters from Kuso Miso Technique but certainly Abe, who sits outside the public toilets, asking good-looking men if they "want to do it" and then shows them his penis.
Prince Charming: Mostly Kagami, but Asahina is tempted to invoke this trope.
Yandere Kanojo: Shuuei Mori. In his introductory chapter, the first thing he says to every guy he meets is "Hey, wanna go to a hotel later?".
Murciélago has the protagonist Kuroko whose biggest priority always seems to be getting a pretty lady to sleep with her.
Unfortunately, this trope is played completely straight in Associated Student Bodies, a furry comic about a young lion who discovers his homosexuality while living in a nearly all-gay dorm at college. While the story is presented, and usually marketed, as a more or less "realistic" story about gay issues, pretty much all the gay characters are presented as feverishly sex-obsessed, having polyamorous relationships with each other and just generally banging each other at every conceivable opportunity. The trope reaches its apex in issue 5, where it is revealed that the gays at Daniel's college organize a huge orgy every New Year's Eve at his dorm.
Chelsea Boys plays it straight with some characters, and averts it with others. The main character's best friend pretty much says that this trope outright, and that the main guy is going against all common gay logic in wanting to be monogamous.
Averted in the Furry Comic Circles though unlike the other dozen or so gay furry comics it hasn't yet devolved into this.
In the Furry Comic Tank Vixens seemingly every girl in the 101st Tank Crushers is sleeping with all the others save Firen and Sonya.
Wallace Wells, Scott Pilgrim's cool gay roommate, is characterized with this trope, even going so far as to hang a lampshade it when chastising Scott for infidelity.
Scott: Double standard!
Wallace: Hey, I didn't make the gay rules. If you don't like it, take it up with Liberace's ghost!
Guy Bennett in Another Country has apparently seduced anyone and everyone at that college, and probably their brothers too.
Inverted in Joe Haldeman's award-winning SF novel The Forever War. As a population-control measure the Earth government in the future encourages homosexuality. When the hero and his girlfriend, a hetero couple, are hospitalized together their gay doctor teases them with this trope. "Still in separate beds?"
Vanyel is practically celibate when he doesn't have a lifebonded partner, but it takes his father most of his life to get over the knee-jerk assumption that being gay means being not only promiscuous but also a pedophile.
David Reuben, the author of Everything You Always Wanted to Know About Sex but Were Afraid to Ask, sincerely believed that this trope was inviolable law. Along with the perpetuation of the myth that Coca-Cola made an effective spermicide, the preaching of this stereotype was what made the book infamous after its initial popularity died down.
In Francine Rivers' The Mark of the Lion trilogy, this is played straight with every major homosexual character in the series. Justified since most of the heterosexual characters are pretty promiscuous, too. It isAncient Rome. Averted with Prometheus after his conversion in the last book, mostly because he doesn't want to be gay.
Live Action TV
Dante's Cove is made of this trope. Kevin and Toby are probably the most monogamous in the cast, with only a couple of "slips" from each of them.
First it's Inverted with Kurt, who was the only one of the New Directions boys who as still a virgin until early third season while everyone else was getting around. He lost it to Blaine, making them the last ND boys to lose their virginity until Rory joined.
Brittany's situation is similar to Santana's. While she has almost certainly slept with nearly every boy in the school and more than a few girls, she is fully comfortable with her bisexuality and could date a girl just as easily as a guy.
Played straight (ahem) with Sebastian.
13 on House: almost immediately after she was revealed to be bisexual, she started picking up one-night stands, and eventually became involved with Foreman. This behavior stemmed from the knowledge that she was slowly dying, and eventually accepts her shortened lifespan. She is later shown settling down with another woman by the time she leaves the show for good.
Inverted with Barney and his gay brother on How I Met Your Mother — at first it appears that his brother is as much of a hedonistic swinger as he is, but then Barney finds out that he's settled down and engaged to be married. Naturally, Barney is horrified that his brother has gone monogamous. It's probably no coincidence that Neil Patrick Harris, who plays Barney, is gay and in a committed relationship in real life. In fact, the episode aired around the time he came out of the closet. But then played straight in a later episode that revealed that they're separating, because Barney's brother had been cheating at least twice a day for some time, despite being married and having children.
The L Word gets accused of fostering this image despite having a few committed couples considering how much bed-hopping goes on, with Shane having the most. As a result there's a fair number of real life lesbians who despise the show for it, among other reasons, and it doesn't help that by the end of the show nearly every relationship was ended.
Noah's Arc: Played straight with Ricky, though some Character Development over time helps to give him a bit more depth.
Stuart on the original UK version of Queer as Folk even told Vince he wasn't really gay, but "a straight guy who has sex with men", because he preferred monogamy to sleeping around.
It's even worse in the American version (pictured above), where there are two monogamous couples, and the rest seem to wake up in a new bed every day, and in one of these couples the term "monogamous" has rather wide definitions. Any gay couple who chooses to settle down is accused of conforming to heterosexual norms or turning into "lesbians" by Brian. Only Brian really disbelieves in monogamy, but Justin tries to change him.
Inverted by The Real World's Hawaii season. Justin was openly gay and the only roommate who wasn't a drunken hedonist. He actually left the show because he was sick of their crap.
In one episode of Sex and the City, an Australian gay guy explains that he's in an open relationship with his partner, the rules for pickups being "no last names, blow-jobs only" on the basis that it's "unrealistic" to expect monogamy from a gay guy.
Played with in Six Feet Under. David and Keith were not above giving their plumber a blow job just because, and the local gay men's choir is used basically as a sex club. Further, when Keith has a security job that takes him out of town, they mutually agree that each may have unlimited one night stands as long they don't sleep with the same guy more than once. They eventually change their minds by the end of the series after deciding that the lack of monogamy was doing more harm than good to their relationship and become completely monogamous.
Inverted on Stargate Universe. The straight characters have a fair amount of relationship drama, and the sole gay couple (Wray and Sharon) have the most stable relationship on the show.
In the Alternate Universe episode "Epilogue", where the crew were stranded on a planet, eliminating any chance that they might ever be reunited with their loved ones, Wray mentions that that while she had gone on a couple dates with another woman since being stranded, her love for Sharon was getting in the way, providing a rare case of a homosexual character choosing to remain celibate despite having the option for a relationship.
An old MTV late night series called Undressed had one gay character (who seemed to be trying to "convert" his roommate) explain this as something of a perk for being gay. His logic was while women are conditioned from a young age not to put out, guys are conditioned/encouraged to be more promiscuous and thus have less reluctance to sex in general, ergo it's easier to have sex if you're a gay man than a straight man because the target is more willing.
Jack on Will and Grace (Arguably every character on that show. Even the straight ones. Then again, it is New York.)
Lampshaded in this exchange from an episode where Will's in a small town, looking to buy a home:
"Me and the guys were wondering... being gay and all, since there's no women around to say no... you must be just doing it all the time, right?"
"Oh, nah. I'm sure I don't do it any more often than you do, probably.
In the Degrassi episode "Moonlight Desires" Marco catches his boyfriend Dlyan in bed making out with another guy. Dylan tells Marco that he wants to be free to have an open relationship and see other people as well as Marco. Marco says no so they break up because Dylan would rather have multiple partners than have Marco.
Never Wipe Tears Without Gloves shines a light on this. In the eighties this trope was generally believed to be true of gay men which in combination with the rapid spread of AIDS was used against them. The characters in the series land on both sides of the prejudice. Paul Really Gets Around and as much as Rasmus loves Benjamin he wants an open relationship. Benjamin, on the other hand, only sleeps with Rasmus and Seppo and Lars-Åke are in a monogamous relationship.
The book series gives a lot more depth to the trope. For the majority of the promiscuous characters the desire to sleep around is rooted in the knowledge that they're not accepted outside of their own community. Casual sex with other men becomes a way to express their sexuality after so many years of hiding it.
In The Savage Eye, the homophobic Mick 'The Bull' Daly claims that all 'quaaares' will try to trick you into 'riding' them.
Lampshaded and played with by Shane who tell Amy who's confused about her gender preference that while gay men are sexually agressive and only looking to hook up most lesbians want to bond and nest build.
Game of Thrones. In the novels Ser Loras is in love with King Renly who is assassinated; heartbroken, he joins the Kingsguard which swears an oath of celibacy. In the TV series he's shown to be actively flirting and sleeping with other men.
Angels In America has Armored Closet Gay Roy Cohn, whose many sexual encounters with men are the reason he's dying of AIDS. It also contains an aversion, in that we are never told much about Prior's sexual history despite him being who has AIDS but is implied to have been faithful to Louis (except for the one time that was supposedly when he got infected), but Louis is said to have played around in the past. It's later implied Prior has been letting Louis screw around ever since he got AIDS, which is made all the more heartbreaking when Louis leaves him.
This trope is a focal point in The Normal Heart. Many of the gays refuse to give up sex even though it may be the way the then unknown AIDS is transmitted.
While not involving sex specifically, Oshare Bones is rather flirtatious despite claiming to be waiting for a reunion with his long-lost lover. One of his victory quotes against Ocean Prince in Puyo Puyo! 15th Anniversary asks for the prince to "invite a lot of nice gentlemen" to the ball he would be hosting; in the same game, Oshare also expresses interest in Lemres, Satan, and Zoh-Daimaoh, even suggesting that he and Zoh go out on a date sometime.
This is a big part of Blur the Lines. Though the main characters, Rick and Drew, are partners, they frequently seek out sex with other men. They are also both OK with the other's promiscuity, leading to a My Girl Is a Slut scenario.
A minor example from Questionable Content - one character lives in a girl's liberal arts college dorm with high concentration of lesbians, who exist in a state of constantly shifting Love Dodecahedron. She is also part of it, but later on expresses reservations about being in that situation, eventually hooking up in a monogamous relationship with a girl outside the college. Later on, Marten's gay father is introduced and actually proposes to his long term boyfriend, so it seems that not all (or even most) gays are promiscuous in the QC verse.
A great running gag of this trope is Batuo the main gay Asian in Tales of a Gay Asian though he tends to like big fat meaty...White guys.
In Fans!, Meighan's skirt-chasing is her biggest weakness (and was, for some time, her only real personality trait). Ally even depended on this as part of her plan to Break Rikk's Heart To Save Him — in fact, it was the only part of the plan that worked. note Ironically, this happened shortly after Meighan had shown her first sign of depth by forging a lasting friendship with Tim... based on his HAVING exactly the self-control she wouldn't have with Ally.
Complicated in the Whateley Universe. Poe Cottage, which is the LGBT dorm at Superhero School Whateley Academy, does have some gays who are taking advantage of this. But they're teenagers who have only just been allowed to express themselves, and they have a like-minded roommate. On the other hand, other gay kids are refraining from sex completely, or staying in monogamous relationships. Saladin, the only gay boy who has a point of view storyline, is strictly monogamous and seldom even sees his boyfriend.
Averted and played straight (ahem) in Where The Bears Are. Nelson and Todd are strictly with each other, but most of the other main characters are not in exclusive relationships, even the married ones..
One episode of Drawn Together had Xandir go on and on about having had a LOT of gay sex in his life, even though he had only been out of the closet for a season and was not shown to have had many partners. Less egregious than other examples since Drawn Together has next to no continuity anyway and everyone is a massive pervert except (sometimes) Clara, so it has less to do with his sexuality and more the everyone is a sex fiend.
As mentioned elsewhere on this wiki, used to terrible effect in a Family Guy episode where Peter is given an injection that makes him gay. The supposedly pro-gay rights episode presents the injection as making him hyper promiscuous and being even less interested in supporting his children than usual, which is saying something.
One of the gags in the episode is predicated on the idea that every gay man will have sex with strangers in public unless given very specific instructions not to.
It also implies that any gay guy would be totally willing to have an 11-way with strangers. It would've been better if it were only Peter like this, because it would make sense for straight Peter to want an 11-way with 10 ladies, but it's still pretty bad.
Parodied on The Simpsons when Homer, as a love counselor, advises the men who want to break up with their dance partner in a gay club to simply turn to their right.
In the South Park episode "D-Yikes!" Mrs. Garrison thinks this is true of lesbians and tries to hit on one who's clearly spoken for. When the town was hit by the metrosexual trend, the then-male Mr. Garrison was eager to spend some quality time with one of any number of men he mistook for gay.
Played straight with Mr. Slave, who managed to out-whore Paris Hilton.
Then again, this is Mr. Garrison we're talking about here.
Chef: Children, there's a big difference between gay people and Mr. Garrison.
