->''As regards sexual intercourse with older or younger copies of yourself, it's incest in [[AlternateTimeline branching]] or [[SetRightWhatOnceWentWrong changeable]] timelines, and masturbation in [[StableTimeLoop inevitable]] timelines. In either case, yes, it is gay.''
-->--[[http://tailsteak.com/archive.php?num=491 tailsteak.com]], "Basic Time Travel Etiquette"

It's a simple tale: Person [[CloningBlues photocopies self]], or travels to an AlternateUniverse, or [[TimeTravel another time]]. Person meets self. Both selves [[IfYouKnowWhatIMean make beautiful music together]]. After all, what better person to be most intimate with?

Probably more prevalent in [[FanFic fanfiction]] than in original works, but it's out there. Technically, any [[FoeYay intimacy]] between a character and their EnemyWithout will be {{Selfcest}}, too.

Expect much argument amongst the characters and/or fans as if this qualifies as actual sex, incest, or masturbation.

Also known as {{selfcest}}, autoincest, or incesturbation. See also OppositeSexClone, TwinThreesomeFantasy, MyOwnGrampa.

In RealLife, a person who would like to do this is a {{Narcissist}} -- or in truly extreme cases, an autosexual.

!!Examples

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''[=~Ranma ½~=]'': Both the manga and anime explored this, though in different manners:
** The anime {{filler}} story, which came first, created a female-only (and ''demonic'') copy of Ranma that tried to seduce him to steal his life force, causing him to stumble around zombie-like during the day.
** The manga version centered on a haunted mirror, which created identical copies of whoever looked into it. Since the mirror had [[SoulJar trapped the spirit of a girl who had longed to have a boyfriend]], any resulting copies would then chase anyone of the opposite sex, and try to date them. When a mirror-copy of girl-Ranma was made, she was immediately smitten with boy-Ranma, and she tried to bed him on her very first night of existence. At the end of the story, a male clone was created accidentally, and both copies happily hooked up (since it would take another week for the seal on the mirror to be fixed, whatever [[IfYouKnowWhatIMean they did afterwards]] belongs [[PowerPerversionPotential in the realm of imagination]].
* ''[[YesPrecure5 Yes! Precure 5]]'', when each Pretty Cure besides Dream is forced to face an EnemyWithin while wearing the Mask of Despair. Cure Lemonade faces a creepily affectionate version of her civilian self.
** Also, a sticker set for the second season exists pairing each girl up with her implied or stated love interest: Dream with Coco and Komachi with Nuts, both of which became canon in season one; Karen with Milk, which [[HideYourLesbians can't be outright stated but is pretty darn close]]; Urara and Rin with Syrup, both of which are currently implied (but Urara seems to be winning, despite Toei earlier saying otherwise... Rin has bad luck with boys, doesn't she?), and Kurumi with... Milk again. Herself. Yeah.
* Happens in the second episode of ''{{Kaiba}}''; the woman who helped the titular character sneak onboard a spaceship copies her own memories into his body and the two of them have a little fun together... which is quite disturbing given the series' surreal and childlike artstyle. Then the copy kills the original for fear of being deleted.
* Technically, the implied attraction between {{Madlax}} and [[spoiler:[[MindScrew her progenitor/creator/original self]] Margaret]] would be this, seeing how she is her [[spoiler:EnemyWithout of sorts]].
* In {{Hentai}} manga ''Alice in Sexland'', an artisan created a cupboard that can create a perfect male (and perfectly horny) clone of its female user.
** More like a "futanari" version than male, but yeah.
* In ''KatekyoHitmanReborn'', the relationship between Mukuro and Chrome tends to feel like this. Their names are actually anagrams of each other, and they look incredibly similar (other than the gender difference), coupled with the fact that they ''share a body''...
** And at first she didn't even look so much like him, it probably was Mukuro himself who made her cut her hair to look like him.
*** Actually it was [[LoonyFan Ken]], [[HoYay Mukuro fanboy's]] idea
** Let's face it -- most people feel [[http://www.onemanga.com/Katekyo_Hitman_Reborn/237/15/ Tsuna and Kyoko]] are the closest thing to this without really being related.
** And then there are all those fanworks that pair up the boys with their [[TimeSkip "ten years later"]] versions of themselves...
*** There's even official art of the characters together with their older selves.
* Closely related: Jail Scaglietti of ''MagicalGirlLyricalNanoha'' impregnated [[spoiler:a perfect clone of himself into]] Uno, who was revealed in the third ''[=StrikerS=]'' [[AudioAdaptation Sound Stage]] to be his OppositeSexClone. Of course, he likely did it [[MadScientist in a scientific way]], but the lack of information on how he specifically did it inspired [[RuleThirtyFour some theories that are more base]].
[[/folder]]

[[folder:Comics]]
* Jamie Madrox (a second-string [[Comicbook/{{X-Men}} X-affiliated]] character) has the power of self-duplication, which allows him to split into multiple physical copies of himself, sometimes with distinct personalities. Guess what trope comes up in about 90% of Madrox-related {{Fanfic}}.
** One of Madrox's duplicates brings out the subject when he's sitting bored at a bar. He indicates he'd rather continue to be bored.
*** Related, and lacking its own trope: the Madrox in ''Universe X'' kills and eats a copy to survive in a barren wasteland; all of him become a Wendigo as a result.
** And it's an old question in ''LegionOfSuperHeroes'' fandom whether Triplicate Girl sleeping with herselves would be [[{{Twincest}} incest]] or masturbation...
* An unusually blatant example, the Sentry and the Void are both alter-egoes of the same man, split into two bodies, who have passionately kissed on at least one occasion.
** [[spoiler:Void tells Sentry he loves him and then aggressively tongue kisses him. Sentry responds by [[HurlItIntoTheSun TOSSING VOID INTO THE SUN!]], so he obviously didn't enjoy it.]]
* And this trope wouldn't be complete without the ''{{XXXenophile}}'' story "Dopplegangbang".
** ''{{XXXenophile}}'' delved into the trope more than once, in fact. There was also a story titled "Self Indulgence", and possibly others too.
*** Yep. Clones in "Family Reunion", and a situation in "Heart of Stone" where a cleric has to turn two of her fellow party members into illusionary duplicates of herself in order to satisfy the conditions of a curse.
* [=DupliKate=] (who has [[MesACrowd self-duplication]] powers) from ''{{Invincible}}'' has had people walk in on her while she's... enjoying herselves... multiple times.
** Uh... no. Atom Eve walks in on ''Rex Splode'' having sex with multiple Kates, then later Rex walks in on Kate and the Immortal. Kate is not screwing herself, she's just pleasuring different guys in multiple ways at the same time.
* Once he discovers that [[spoiler: the Jaeger-monster]] is [[spoiler: the AnthropomorphicPersonification of his anger]], [[{{Finder}} Magri White]] declares that he can do as he pleases with him, and proceeds to play tonsil hockey with him.
* ''{{Preacher}}'' shows the unpleasant consequences that can occur when a man blessed/cursed with the [[CompellingVoice power of God]] orders you to Screw Yourself (though he put it more crudely than that). The victim committed suicide a couple of pages later.
* In ''{{Cerebus}}'', the title character learns about halfway through the series that he is a hermaphrodite whose [[YouFailBiologyForever genital arrangement could have led to him impregnating himself]] if his uterus had not been permanently damaged when he was a child.
[[/folder]]

[[folder:Fan Works]]
* Lavi and Deak from ''[=~D.Gray-man~=]''. Also, [[spoiler: Allen and the Fourteenth Noah]]. And I've actually seen a fic where Allen was paired with his INNOCENCE.
** [[IncrediblyLamePun I doubt it was very Innocent afterwords.]]
* Too many ''{{Naruto}}'' hentai to count. OrSoIHeard...
** It's called the Harem Jutsu for a reason.
*** Ba-dum-tish!
* ''[=~Ranma ½~=]'' lemon fics use this with Ranma's male and female sides. Some would say [[{{Squick}} far too often]]; others would say [[FetishFuel not often enough]].
** And it's not always strictly with Ranma(s); [[ShamelessSelfPromoter for example]], there is this [[spoiler: Nabiki×Nabiki]] lemon fanfiction entirely about this trope: ''[[http://stfan.free.fr/OneShots/N.htm Narcissism]]''.
* Any anime where the main character has a split personality where the other half is a {{Bishonen}} falls into this, such as ''[=~D.N.Angel~=]'' and ''{{Yu-Gi-Oh}}!''... ''especially Yu-Gi-Oh!''
** Ohoho, especially ''Yu-Gi-Oh!'', INDEED. Not only does the titular character fall into this, but other characters of sorts who had an alter ego or possessed self of some form.
* [=Youko!Kurama×Shuuichi!Kurama=] is seen occasionally in ''YuYuHakusho'' fanfic, but they're not usually portrayed as the same person.
* There is a really [[JoJosBizarreAdventure bizarre]] (pun completely intended) lemon which included Will/Gyro and Jonathan/Johnny pairings. May or may not count though as Gyro and Johnny are their alternate universe incarnations, but look and act very different.
* Though a fandom thing, ''[[StarTrekVoyager Star Trek: Voyager]]'' wound up with this due to the actor for Tom Paris having been on ''Next Generation'' as an entirely different character. So a lot of fanfic winds up with the two characters meeting up in some bar, drunk. (Or, alternatively, just doing a RecycledScript of someone else's fic with Tom being such a narcissist he heads to the holodeck to copy himself.)
** Of course, there is all the in-canon times ''Voyager'' crewpeople have met duplicates of themselves. Or not met the duplicates of themselves. They really do give the actors lots of roles to play.
* {{Supergirl}} has an alternate-universe doppelganger named Power Girl, who is basically her, only ten years older and more aggressively individualistic (she doesn't wear Superman's costume), with shorter hair and... well, if you've ever heard of the character, [[MostCommonSuperpower you know what else]]. There is a(n un)surprising amount of Supergirl/Power Girl slashfic.
* The Japanese ''MegaManStarForce'' fandom is full of Pat/Ray fanarts.
* Various doujins of ''{{The Melancholy Of Haruhi Suzumiya}}'' have this. Specifically Mikuru and her future self with some help from Kyon.
* This troper is certain there's rather a lot of shipping involving [[DoctorWho two of the Doctor's various incarnations]]. [[OT3 Or more.]]
* ''DannyPhantom'' has somehow gotten Danny Fenton/Danny Phantom pairing fan-works even though it's impossible because he's one person... (Unless you count the thing with the dream catcher that can split him into two halves [[strike:once]] twice.)
** Then, of course, there's also Danny/[[OppositeSexClone Dani]]...
** ... And don't forget his [[FutureMeScaresMe future self]]. Before you think about that too hard, there is an actual fic for that: [[http://www.fanfiction.net/s/3317236/1/Narcissism Narcissism]]. It's actually quite hilarious and sadly DeadFic.
** There's always the fact that one of his powers is actually creating duplicates of himself. And yes, one of the duplicates can go back to human with the other staying as ghost. It is true that only Vlad did that, but it's a matter of training for Danny to do it.
** Oddly, SympatheticVillain Vlad -- who ''can'' currently duplicate and has been portrayed as somewhat vain evades this treatment, [[FanGirl thank god]].
* ''TheWorldEndsWithYou'' has attracted a lot of this, thanks to the implication that there are alternate universes that may be crossed.
* Members of the ''{{Tales of the Abyss}}'' fandom have taken the implications of [[CloningBlues replicas]] to its logical conclusion.
* While the prospect doesn't exist, the fandom of ''ToLoveRu'' continues to clamor for an ''actual'' OppositeSexClone ''conveniently'' given a place in the male protagonist's UnwantedHarem, due to his [[spoiler:AttractiveBentGender as a result of a TransformationRay]]. Then again, because of the female protagonist's status as a GadgeteerGenius, the likelihood of this happening isn't so far out...
* This troper recalls seeing a fanfiction that shipped [[TouhouProject Yuka Kazami]] and her clone from her DoppelgangerAttack.
* From the [[http://daitrombe.net Daitrombe]] of [[SuperRobotWars SRW]] [[FanDom fandom]]:
** Fan's opinion about Ingram & [[OppositeSexClone Viletta]]? [[http://daitrombe.net/image/show/20282 this!]], [[http://daitrombe.net/image/show/19625 This!!]], add a kid named cobray as [[http://daitrombe.net/image/show/19999 their son, THIS!!!]]
** Fan's opinion about Raul & [[HalfIdenticalTwins Feona]]? add Despoiniz and [[http://daitrombe.net/image/show/3772 THIS!!!]]
* Ever since TombRaider: Underworld, there's been an increasing number of pics with Lara and her Doppleganger from that game.
* [[http://www.eskimo.com/~vecna/brothers.html This]] ''{{Gargoyles}}'' fanfic features multiple clones of [[MadScientist Anton Sevarius]], some of them gender-swapped, and the daughter that one pair among them decided to create the old-fashioned way as an experiment. (Note that this story occurs more than halfway through an [[http://www.eskimo.com/~vecna/gargoyles_fanfic_master_list.html extensive]] fanfic continuity.)
* ''[=~Pokémon~=]'' has at least one in doppleganger shipping: between Ash and a [[WholesomeCrossdresser cross-dressed Ash]] and the pseudo-example of malevolent shipping: Ash and the king of pokelantis; who takes Ash's form
[[/folder]]

[[folder:Films -- Live Action]]
* A deleted scene in ''AustinPowers: The Spy Who Shagged Me'' had Number 2 from the past and future in bed, [[SmokingHotSex smoking cigarettes]], and the older one musing that it's not technically cheating.
** This is based on the gag actually used at the end of the movie, with two temporally displaced versions of Austin ending up in bed with his LoveInterest.
--->'''Austin:''' Paging Dr. Freud!
* ''[[StarTrekTheOriginalSeries Star Trek VI]]'': Kirk to fellow Klingon-gulag inmate Martia, who turns out to be a shapeshifter, formerly in the form of an attractive female humanoid and now in the form of Kirk himself:
-->'''Kirk:''' I can't believe I kissed you!\\
'''Martia:''' Must have been your lifelong ambition!
* In ''The Sixth Day'', Adam Gibson, who was cloned without his knowledge, tells the villain he should clone himself while he's still alive. The villain asks if it would be so he could get Adam's unique perspective. Adam says, "No, so you can go screw yourself."
** "When I said you should screw yourself, I didn't mean it literally."
* [[SilenceOfTheLambs Bufallo Bill would.]]
[[/folder]]

[[folder:Literature]]
* ''TheManWhoFoldedHimself'' by David Gerrold.
* "'—All You Zombies—'" by RobertAHeinlein. In which the unmarried mother, the seducer, their illegitimate child, the recruiter for the time-travel corps, and the bartender to whom he/she tells his/her story all turn out to be the same person.
* Heinlein's ''TimeEnoughForLove'': Lazarus Long at first objects to screwing his own [[OppositeSexClone identical-twin female clones]], but relents when they assure him it's no more than "Narcissus loving himself".
* ''DowntimingTheNightSide'', by Jack Chalker. Not as squicky as it sounds: By the time the hero/heroine hooks up with him/herself they are essentially different people thanks to a GenderBender, several [[StableTimeLoop time loops]] and the side effects of the book's time travel {{Phlebotinum}}.
** F.M. Busby wrote a short story with a similar concept using {{Reincarnation}} instead of a GenderBender. The hero dies and finds himself reborn in the past as the girl who will eventually become his beloved wife. He/she then gets to reexperience their life together from her perspective, eventually giving birth to a daughter who turns out to be (surprise, surprise) him/herself yet again, reborn once more into the past.
* Fifteen-year-old Henry finds an outlet for his pubescent sexual urges this way (and, it's implied, repeatedly) in ''TheTimeTravelersWife''. For added fun, his father walks into the room and catches him (them?) ''in flagrante''. Henry rationalizes having gay sex with himself as a parallel to masturbation, and the obvious course of action that "anyone" would take in his situation (thankfully, his eponymous ''wife'' never needs to hear about it).
* ''{{Parallelities}}'' by Alan Dean Foster not only has the main character bedding an alternate female version of himself while traveling through TheMultiverse, he eventually finds an alternate Earth populated entirely by doubles of himself.
* The ''{{Darkover}}'' novel ''Two to Conquer'' has the main character meet up with an exact physical duplicate of himself. The expected interaction occurs.
* ''StorkNaked'', by PiersAnthony.
* ''[[http://www.strangehorizons.com/2008/20080818/sexghosts-f.shtml Sex With Ghosts]]'', by Sarah Kanning.
* While the book doesn't get that far, in ''Magyk By Design'' by Esther Friesner, a cat (talking, magical) named Scandal gets split up into a number of copies by villains (who can control the copies). By the end of the book, he reabsorbs them. ''Except'' for the one representing his female side, who being just a kitten was useless to them and out of the fight. He's accelerating her maturation, for this trope's purpose, with her full encouragement. (They ''are'' the only two cats in this world...)
* An early Ursula K. LeGuin story had a set of about nine or ten clones (a hive mind?), some male and some female, who join some place where there were already two normal people working. When the clones have sex with each other, one of the non-clones says, "Oh, let them have their damned incest!" and (as in the anime example above) the other says, "Incest or masturbation?" (The clone-sex wasn't a major plot point.)
* This trope goes right back to [[TheBible Adam and Eve]], if you believe the whole rib thing. And then there are the interpretations that suggest she was made from a different bone entirely, one present in many mammals but not in humans.
** That would technically make every sexual encounter since then incest. Squick.
*** It already is if you think about it. We're all cousins, after all.
**** Either way you look at it (Biblical or Scientific) we all decended from the same place. Now, if you'll excuse me, [[BrainBleach I have to go take care of something]].
* Used romantically with several pairings amongst the {{Starfish Character}}s in ''Scorpion Shards''. They are soul mates, so to speak, but it gets a little weird when one of them realizes he can't fall in love with someone who isn't part of the group.
* The main character in James Alan Gardner's ''Commitment Hour'' spends the last few chapters of the book [[spoiler: having "impure" thoughts about a female clone of himself]]. To make matters worse, [[spoiler: their minds are linked to share memories between them, so she "hears" every one of the thoughts. ''And likes them'']]. The end of the book [[spoiler:strongly implies the the character ends up romantically involved with his own clone, while a third, hermaphrodite clone has a whole 'nother squick going on]].
[[/folder]]

[[folder:Live Action TV]]
* In ''RedDwarf'', "Parallel Universe", the crew go to a parallel Red Dwarf where humans are all of opposite genders, and Lister gets drunk and sleeps with his female self, to the disgust of both versions of Rimmer.
-->'''Female Rimmer:''' How could you possibly contemplate making love to yourself?\\
'''Male Rimmer:''' Well, [[{{Narcissist}} why break the habit of a lifetime]]?
** Of course, Female!Rimmer was also trying to come on to Male!Rimmer, using (or planning on using) the same crappy pick-up lines and talent for hypnosis he mentioned at the beginning of the episode...
** The parallel universe had male and female roles completely switched, so female-Lister gets male-Lister pregnant. This is revealed immediately before the end of the episode, and what happens to the fetus is dealt with in some fast scrolling text at the start of the following season...
** Ironically, in "Rimmerworld", he decides to make an OppositeSexClone of himself... somehow. And then have sex with the clone, despite some misgivings:
--->'''Rimmer:''' This of course created the most enormous moral dilemma. Technically, she would be my sister, and therefore unable to take me as her lover. After much soul searching, I reluctantly decided, "What the hell", I just wouldn't tell her.
** In the episode "Camille", they met a Gelf who appeared to each character as their "perfect companion", which everyone assumed to be their perfect ''female'' companions. Predictably, Lister saw Kochanski; slightly less predictably, Rimmer saw a fairly plain, underachieving hologram; and Kryten saw a robot which looked very similar to him (because they're from the same series, series 4000), but had a distinctive personality and looked slightly more feminine. The Cat, after much excitement, finally sees [[spoiler: himself.]]
--->'''Cat:''' [[spoiler: I'm the object of my own desire?!]]\\
'''Gelf [[spoiler: Cat ]]:''' Can you think of anyone more deserving?\\
'''Cat:''' Well, when you put it like that, I guess not!
* ''{{Perversions of Science}}'' used this concept. A man decides that no woman is good enough for him, so he decides to create "the perfect woman" by having a sex change and then going back in time to have sex with himself.
* A skit on ''TheManShow'' had Adam Corolla and a clone of himself, eventually coming to the conclusion "After all, it's only me, right?"
* On ''BuffyTheVampireSlayer'', Willow's LesbianVampire EvilTwin acted interested in getting physical with her human counterpart, licking the [[{{Squick}} squicked-out]] Willow with lustful intent.
** Not to mention during their goodbye hug:
--->'''Willow:''' Hands! Hands!
* One of the ways the illusion-casting Candice from ''Series/{{Heroes}}'' tries seducing Sylar is by appearing to him ''as Sylar'' ("Or something more familiar... if that's what you're into.").
* In ''{{Sliders}}'', Quinn once discusses his adventures on a talk show, and mentions having met a female version of himself. He is immediately asked, "Did you have sex with her?" (We never really found out if he did, though they did kiss. She was AxCrazy, anyway.)
** We actually get to see them meet early on -- though it's something of an ItWasHisSled episode as far as that goes. [[TrailersAlwaysSpoil The trailer promoted this episode on that basis, but in-show you wouldn't know until near the end.]] [[spoiler:Quinn is attracted to Logan; Logan only wants his sliding device, but will play along to get it. In her EvilConfession, Logan says, in effect, that she is his EvilTwin --]] it's just a minor slide from XX to XY, right? [[spoiler:GoodIsDumb, which is why she figured it out first.) In the end, he slides away with a remote, with her sliding after with a time lag...]] Pity we never meet her again. That was also the episode which, in the end, changed the range of the slider remote from "San Francisco only" to "all the way to LA..."
*** Technically, GoodIsDumb isn't the reason. Access to the biometric scanner thingy helped too.
* Although never even hinted at in-series, the use of "[[TheNthDoctor regeneration]]" in ''DoctorWho'' and the propensity for the Doctor to meet his past selves has all the inevitable implications. Then again, considering that the new series certainly isn't shy about sexual innuendos and even less about homosexual ones, if it ever does a multi-Doctor episode it would be surprising if it ''wasn't'' mentioned.
** They've done a two-Doctor episode (the 2007 "Children in Need" short). There was no self-love involved except for a speech by Ten about how much he had loved being Five (included because the writer, producer, and actor all grew up during Five's tenure as the Doctor).
** In the last episodes of the 4th season, we wind up with [[spoiler:three versions of the same Doctor: the Doctor proper, the Hand Doctor and the [=DoctorDonna=].]] Captain Jack, when finding out that "there are three of you now?", says "I can't tell you what I'm thinking right now."
*** And speaking of Captain Jack, it was hinted at in "Utopia" that, as a result of his immortality, he could find a version of himself even at the end of the universe... and then when Jack seems to consider this, followed up with the line that it would be the "only person you'll ever be happy with..."
** There is an entire livejournal community [[http://community.livejournal.com/timeslipping dedicated to exactly this.]]
* ''{{Stargate SG-1}}'': Given how much [[ThePuppetmasters puppetmaster]] Ba'al was hitting on [[CrystalDragonJesus Adria]], what he ''might'' have had in plan after one of his clones possessed her may have fit the trope. However, he never got to carry on his plans, so we may never know... which is probably best.
* On ''[[StarTrekDeepSpaceNine Star Trek: Deep Space Nine]]'', Kira's ([[LesYay same sex]]) EvilCounterpart in the MirrorUniverse had the hots for her.
** Mirror-Kira [[AnythingThatMoves has the hots for everyone]].
**** And [[FetishFuel we love her for it]].
* ''MysteryScienceTheater3000'' references this trope a couple of times, once when talking about a TimeTravel movie (''Time Chasers''), and once where a character was in a computer simulation with a copy of himself (''Overdrawn at the Memory Bank'').
* Rob Brydon's onscreen kiss with Ben Miller on ''{{QI}}'' after an episode's worth of jokes that they were identical. Ben: "So that's what it's like!"
*Though nothing comes of it [[spoiler: save a broken neck]], ''TheSarahConnorChronicles'' has some terribly disturbing [[StarBoarding one-sided]] LesYay from Cameron toward Allison.
** Disturbing, maybe. [[FetishFuel Hot? Definitely. It's Summer Glau... and the only thing better than that is TWO Summers.]]
* Robin from ''HowIMetYourMother'' honors this trope as well. Once she gets back from Argentina, she undergoes an identity crisis while talking a lot, in her dreams, to her vacation double. When Robin is finally herself again, she mentions that 'vacation Robin' popped up in her dreams again and they went all the way.
-->'''Robin:''' That chick knows what I like.
* On ''[[That70sShow That '70s Show]]'', an episode revolves around [[HomoeroticDream Fez having a dream where Kelso gives him a sponge bath.]] At the end of the episode, Kelso has the same dream. And likes it.

* Hot Sauce and Ice Cream, by TomSmith, features this briefly near the end, before it turns into a TwinThreesomeFantasy.

* The Pink song "Sober" now has a video out. In the middle of it, Pink, in naughty lingerie, is making out with... another Pink in other naughty lingerie. Take a look [[http://www.youtube.com/watch?v=89V7hvEmSD8 here]]. Starts about 2:20 and gets intercut here and there nearly to the end.

[[folder:Tabletop Games]]
* The player's handbook to ''Aberrant'' (a White Wolf RPG centered around people developing superpowers as a world-wide phenomenon) contain a chapter with various superhero teams and similar groups across the world (some of which are painfully ethnic). One is the Queer Nova Alliance, an informal group of Novas (superpeople) with 'alternate lifestyles'. One member is Tommy Orgy, whose selection of powers includes self-cloning. It's not made explicit, but what's ''implied''...
** Implied nothing, [[ExactlyWhatItSaysOnTheTin his goddamn name is ''Orgy''.]]
[[/folder]]

[[folder:Video Games]]
* The ''KingdomHearts'' series has a strangely huge potential for this ([[RuleThirtyFour and don't think for a second fandom hasn't picked up on this]]), with Riku and the Riku Replica, Demyx and his waterclones, Xemnas and Xehanort's Heartless (heck, why not Xehanort himself?), Roxas and Sora, Kairi and Namine, and most recently, Sora and [[spoiler:Xion]]. And Roxas and [[spoiler: Xion]]. [[OverlongRunningGag And]] Sora, Roxas, and [[spoiler: Xion]], for a ''threesome'' of selfcest.
** And don't forget the innumerable stories and drawings which pair the Squaresoft [[{{Expy}} Expies]] from ''Kingdom Hearts'' with their original inspirations.
** You forgot the past and present versions of Mickey and Pete, Vexen and Vexen Replica, Sora and Anti-Sora, Roxas and Shadow Roxas, Donald, Goofy and Sora's Master Form (technically), Roxas and Ven, the real and virtual versions of Hayner, Pence, Olette, Seifer, Vivi, Fuu, Rai, Setzer and Kingdom Hearts itself. In ''Final Mix'', there's the real and virtual versions of everyone in Organization XIII, and Larxene and Zexion's copies...
* In the ''AceAttorney'' series, there is... [[spoiler:Diego Armando×Godot]] goodies. [[NoJustNo Just, no]].
** On a more lighter side, but still pretty creepy, is fanart of crossovers between [[MirrorUniverse the US and Japanese counterparts]]. Phoenix (US) seems to be always portrayed as enjoying Ryuichi's (JPN) company [[HoYay a little TOO much]]...
** Don't forget about all the [[spoiler:scarred Matt Engarde/"refreshing like a spring breeze" Matt Engarde]]. There's even a popular doujinshi devoted to them gang-banging Edgeworth.
** Mia. Original, Maya-style or Pearl-style. The third iteration gets a little creepy when one remembers that the channeler is a pre-schooler.
* On the other hand, surprisingly little ''TheLegendOfZelda: Four Swords'' hentai exists. But why write selfcest when the ''official manga itself'' is already catering to the pairing (Red/Blue Link, to be specific)? Freud would love to read that one.
** However, there's quite enough Zelda/Sheik out there to make up for it. Whether male or female (let's not get into ''that'' FlameWar) Sheik ''is'' [[spoiler: Zelda in disguise]]. Fanfics by {{Yaoi Fangirl}}s under the influence of HetIsEw will often make them [[spoiler: separate]] without as much as a HandWave, but the game is a hundred percent clear on [[spoiler: who Sheik is]].
** This trooper has seen fanart of ''Wind Waker'' Link and young ''Ocarina of Time'' Link. Also of ''Twilight Princess'' Link and adult ''Ocarina of time'' Link. And for the ones who want to cross over to shotacon-territory, there's always a combination of the two... including both versions of ''Ocarina of Time'' Link together... a MAJOR case of this trope.
*** Considering that Link is a {{Legacy Character}}, though, the first two examples only apply in a loose sense.
*** Not if you're follower of the {{Reincarnation}} theory. (The only theory that at least remotely explains, how they can all look simmilar, share their skills, personality and NAME.)
* There is a hella lot of Prince/Dark Prince from ''Prince of Persia: The Two Thrones''.
* There's plenty of Raul/Fiona imagery from ''SuperRobotWars'' fans (and at least one famous Raul/Fiona/Despinis). In ''Reversal'', it'd be this trope as they're male and female versions of the same character; in ''[[SuperRobotWarsOriginal Generation Super Robot Wars Original Generations]]'', it'd be {{Twincest}}.
** ''SuperRobotWarsW'' plays this trope better: [[spoiler:Aria Advance, TheLancer to the BigBad, is the male protagonist's OppositeSexClone]]. Doujin artists/writers had a field day with this.
* The eroge ''X-Change'', toyed with the idea, having one of the girls apparently resemble Takuya's female form, but with a different hair color. ThisTroper couldn't actually see the similarity. Uh... I mean [[OrSoIHeard that's what someone else told me]]...
* In ''MetalGearSolid 3'', dress Snake up to look like Raikov, stand in front of Raikov, and ''just wait''.
** In the same series, the ridiculous levels of FoeYay between Solid Snake and his "brother" Liquid Snake.
** Taken BeyondTheImpossible by the marketing campaign for ''MetalGearSolid: Peace Walker'', which so far seems to be [[PlayingToTheFetishes furiously attempting to encourage this as much as possible]]. The first trailer alone depicted four Big Bosses, and at the end they got in a pink box (labelled 'LOVE PACK') which jiggled suggestively, alerting a nearby guard. The second trailer involves soldierly HoYay [[CleanPrettyReliable CPR]] and masculine hand-holding and dialogue about always sticking together, between two Big Bosses. Whether this becomes part of the game or not remains to be seen, but HideoKojima is at least having fun with it.
*** It's now been revealed that a) the four demo-ready character builds are all different versions of Big Boss, and b) the Love Box is indeed a two-person cardboard box and that if two Big Bosses stay still in it for too long, it will start to jiggle around. Not surprising, as [[EvenTheGuysWantHim even the guys want Big Boss]], and that includes Big Boss.
*** The official website gives an innuendo-filled description of the Love Pack, saying 'in the spirit of camaraderie, some may find it comfortable!'. And also reveals that the characters giggle when taking items from each other, because it tickles. Big Boss is officially the gayest thing in an already incredibly gay series, ''and for himself''.
* ''DarkStalkers'': Morrigan and Lilith are technically two fragments of the same soul. The game art depicts them embracing, naked. What did you expect from HornyDevils?
* The BL game {{Kichiku Megane}} features an uke salesman that turns super sadistic seme when he puts on a pair of glasses given to him by a mysterious stranger. One of the game endings features uke salesman/salesman with glasses...
* In ''{{Tales of the Abyss}}'' we have [[CloningBlues Asch and Luke]]. I cannot tell you how many fanfics ThisTroper has seen pairing them together...
** And then there's [[spoiler:Sync/Ion/Florian]]...
* In HellMOO, while (to my knowledge) you can't actually do this, there are flyers advertising clone services that definately hint at this, and it is not difficult at all to become an autosexual.

* ''{{xkcd}}'' has [[http://xkcd.com/105/ touched upon this]] enough for the author to bring up the possibility that it's now "an official xkcd theme".
** And [[http://xkcd.com/267/ here]] too...
* Well, it doesn't involve time travel but Black Mage of ''[=~8-Bit Theater~=]'' had an EnemyWithout moment, but ended up killing the embodiment of his sins (himself) and re-absorbing all of his evil. Then he decides he needs to do something that makes self-love into an atrocity. Thief then [[RuleOfFunny somehow]] gets pictures and blackmails him.
* ''[[http://www.hackcanada.com/canadian/zines/spacemoose/time_machine.html Space Moose]]''.
* ''[[http://overcompensating.com/posts/20060425.html Overcompensating]]''.
* In a ''QuestionableContent'' filler strip, Tai [[GenderBender turns all the men in Northampton into women]]; Marten now looks exactly like Dora, so, [[MemeticMutation just as planned]], [[http://questionablecontent.net/view.php?comic=955 they start to make out in front of her]].
* Used in [[http://www.smbc-comics.com/index.php?db=comics&id=880&override=1#comic this strip]] of ''SaturdayMorningBreakfastCereal.''
* Subverted in a ''RealLifeComics'' strip. Greg and Tony travel to an alternate dimension where everyone is gender-flipped. Upon meeting female Greg, Tony comments that female Greg is kinda hot. Greg's reaction to this is [[{{Squick}} not surprising in the least]].
** Played straight later, when it's revealed by female-Greg that male-Liz is dead. Greg cheerfully tells Liz and female-Greg [[http://www.reallifecomics.com/archive/080916.html "If you two want to hug, don't stop on my account."]]
*** Subverted later still, when Greg's female doppleganger offers to swing by and start hanging out with Greg and Liz, Greg replies with: [[http://www.reallifecomics.com/archive/081104.html "You freak me out in ways I'm not comfortable dealing with. No offense."]] Needless to say, female Greg is offended.

* In the ''Whateley Universe'', this is a serious problem to Jobe, as his now-identical clone Belephoebe is also in the body of his ideal girlfriend. And is his daughter, legally. He restrains himself from the urge to make sweet monkey love to her. [[spoiler: Even after Jobe is turned into a girl. Belephoebe, however, does NOT restrain herself.]]
* In episode 10 of ''RetardedAnimalBabies'', the protagonists travel through the internet, find their creator's Newgrounds profile, and end up entering the beginning of the same episode. Effectively, they have traveled a few minutes into the past and are able to communicate with their past selves. The two Puppies immediately decide to have sex.
* Invoked, and very nearly practiced, by Doctor What in ''AHDotComTheSeries'' "The Narcissus Syndrome" -- with his evil, MirrorUniverse, GenderBender counterpart.

* A sketch on ''RobotChicken'' parodying Best Week Ever, featured Hal Sparks(Portrayed as pretty much all people on that show are, as a stop motion action figure) remarking "If anyone ever made a toy of me, I'd have to make out with it". A few seconds later, Hal is shown making out with a considerably less animate but otherwise identical copy of himself. A moment after THAT, he pauses to cheerfully declare to the camera "It's not gay, it's masturbation!"
* This is of course the [[FreudWasRight very first thing]] a nudist alien does after receiving the secret to paradox free TimeTravel in ''[[{{Futurama}} Bender's Big Score]]''.
* In one of its countless {{Imagine Spot}}s, ''TheSimpsons'' had Homer fantasizing what it'd be like to marry himself. Cue the image of a room full of mini-Homers and two adult Homers swapping tongue.
** "[[BrainBleach AAAAH! UNCUE THE IMAGE! UNCUE THE IMAGE!!!]]"
*** If anyone needs me I'll be on the front porch, rocking vacantly back and forth.
*** Yeesh, I've heard of loving yourself, but that's just going way too far! [[HomestarRunner ''Jibbliejibbliejibblie''...]]
* While Cybertronians are by and large immortal robots who realistically would only have a PurelyAestheticGender, [[TheStarscream Starscream]] in ''TransformersAnimated'' seems to come on to his OppositeSexClone while asking what she represents in him.
** The fact that he's flirting with his opposite-sex clone should make it obvious. It's either repressed sexuality, narcissism, or both. WordOfGod says this isn't true, but they're ''wrong''. So very, very wrong.
* Speaking of Power Girl, the ''JusticeLeague'' animated series used a LawyerFriendlyCameo version of Power Girl (a clone named Galatea) and if you didn't think there as a fuckton of LesYay between her and Supergirl, we weren't watching the same show.
* A recent episode of ''FamilyGuy'' featured Stewie and Brian travelling to other universes, one being where everyone has two heads: One happy, one sad. When we see this universe's Stewie, we see his heads kissing each other. The happy one likes it, while the sad one tries his best to.
* ''AeonFlux''. How has no-one mentioned the episode where Aeon is duplicated and, true to her omnisexual nature, makes out with herself, though only briefly?

* There are some species of animals that are hermaphrodites and are capable of impregnating themselves...
** Lots of plants, too.
* All humans are descendants from [[http://en.wikipedia.org/wiki/Mitochondrial_Eve Mitochondrial Eve]], a single woman that lived about 170,000 years ago. This has the similar implications to the Adam and Eve story: Every sex act ever is between distant relatives.
** There is also a "Y-chromosomal Adam", but he lived 60,000 years ago.
* In a broadly similar vein, Woody Allen once quipped: "I love to masturbate. It's sex with someone I love."
