* Ditto is a Franchise/{{Pokemon}} with the ability to shapeshift into any Pokémon it sees. Once VideoGame/PokemonGoldAndSilver introduced Pokémon breeding, Ditto also gained another unique ability- the ability to breed with ''anything'', regardless of their sex or species. It can even breed with Pokémon that have NoBiologicalSex like Magnemite and Voltorb.

* The shapeshifting [[VampireMonarch vampire lord]] Alucard in ''Manga/{{Hellsing}}'' spent at least some time during UsefulNotes/WorldWarII as a girl. He also flirts quite openly with [[UsefulNotes/HMTheQueen Queen Elizabeth II]] while waxing nostalgic about "old times". She would have been an 18-year-old princess around that time. Do the math.

** From the same mythology dept., the (not-yet-{{blind seer}}) Tiresias (though he was no "natural" shapeshifter; he killed the female of a pair of snakes having sex and got turned into a female. 100 points if you find out how he turned back without using Wiki/{{Wikipedia}}). Another version has Tiresias get turned into a woman by Athena when he saw her naked (but recognizing it wasn't done intentionally, she only turned him into a woman rather than kill him). Later, Hera and Zeus decided to ask Tiresias whether he'd gotten more enjoyment out of sex as a man or a woman. Hera blinded him for siding with Zeus, so Zeus gave him the gift of prophecy to make up for it.

* UsefulNotes/{{Christianity}}: Some versions of HornyDevils steal men's seed as feminine succubi and implant it in women as masculine incubi. The resulting child thus has both a human mother and father, but you just know it isn't going to turn out right with a conception story like that...

-->-- '''"Sara's Little Purple Book"'''[[http://whateleyacademy.net/index.php/9-original-canon/240-sara-s-little-purple-book]], ''Literature/WhateleyUniverse''

* In the Franchise/MarvelUniverse, Xavin of ''ComicBook/{{Runaways}}'', who is technically male, takes on a female form for the sake of their lesbian fiancée. They now have a female ShapeshifterDefaultForm. The Human form, their Skrull form is usually male. The characters are confused too, including Xavin.
* ComicBook/{{Mystique}}, also of Marvel, is made of this trope. Although not as much as Creator/ChrisClaremont wanted; she [[ExecutiveVeto was meant to be]] Nightcrawler's ''father'', [[HomosexualReproduction not his mother]]. Just to fuck with genetics some more in true ''ComicBook/XMen'' style. Y-chromosome? She ''shapeshifted her chromosomes,'' because she's just that badass.
** Slightly averted when she had to avoid a hug and kiss from Contessa de la Fontaine (Nick Fury's lover) while posing as Fury. Mystique had precisely copied his fingerprints, voice print, and retinal patterns to get past security, but if the Contessa hugged her, she would quickly notice that "Fury" was skin and bones, since Mystique didn't have enough body mass to duplicate all his muscles, and her abilities don't allow her to create or assimilate extra tissue ([[DependingOnTheWriter except when they do]]).
* Averted by Hulkling of the ''ComicBook/YoungAvengers''. Though he could presumably become a girl if he wanted to, he never has, and his boyfriend probably wouldn't like it if he did. Interestingly, this wasn't always going to be the case. Hulkling [[WhatCouldHaveBeen was originally going to be a girl]] who posed as a man to fight crime, causing Wiccan to [[SweetOnPollyOliver question his sexuality]]. Then creator Allen Heinberg began to have second thoughts and asked for permission to make the couple unambiguously gay.
* Played with in Skrull Kill Krew: Ryder and Catwalk once had sex while shapeshifted into each others [[ShapeshifterDefaultForm Default Forms]].
* Electro of ''ComicBook/SpiderMan'' fame once had a shapeshifting girlfriend. He would apparently ask her to [[FoeRomanceSubtext turn into Spider-Man during sex]].
* ComicBook/TheDefenders had a short-lived member called Cloud who had two forms: a small cumulus that could project wind, rain and lightning, and a shapely piece of fanservice dressed in a few whisps of cirrus that always looked on the point of blowing away. As the result of a plot involving another team member attempting to seduce them all psychically, she discovered she could just as easily "condense" into a male body. The guys on the team were not pleased.
* Morph of the ComicBook/{{Exiles}} gave this a brief try when he found out his crush was lesbian, but she [[DefiedTrope very quickly pointed out]] that whatever he might make his physical body look like, his gender was still unmistakable.
* ''ComicBook/TheUltimates'': Herr Kleiser is a man because he consumed a man, but after some decades in that form he's ready to consume the wasp and experiment the female form.

* In one chapter of [=OKShark=]'s Eberron story, ''[[http://www.fanfiction.net/s/3703661/1/Eberron_Welcome_to_the_Jungle Welcome to the Jungle]]'', one of the protagonists, a female changeling named Sam, talks about how her father actually gave birth to her due to getting pregnant in female form after picking the short straw and having to seduce a senior Thranish diplomat who was infatuated with Cousin Ailia as part of a plot to secure some incriminating correspondence for blackmail purposes. Her lover Neana (the other protagonist), is rather squicked about the whole thing. Since Neana is very much a lesbian, Sam does not take male form when the two of them get intimate.
* An incredibly unhealthy version in the Young Avengers fanfic Space Oddity. Teddy carried on a friends with benefits relationship with his former toxic best friend, but on the condition that he swap sexes during intercourse. He was not comfortable with this.
* ''Fanfic/ADiplomaticVisit'': [[spoiler:Changelings are fully capable of changing into different genders depending on what their partner likes.]]

[[folder:Film — Animated]]

[[folder:Film — Live-Action]]
* ''Film/StarTrekVITheUndiscoveredCountry'' [[PlayedForLaughs plays this for comic effect]]: Martia, Rura Penthe's resident MsFanservice, can shapeshift between various forms for various purposes, such as changing into a big male to get into a part of the prison where women aren't allowed, or to easily slip out of her chains by changing into the form of a young girl. [[spoiler: During her fight with Kirk, she shifts into Kirk's form, leading to a joke about their previous makeout session and [[{{Narcissist}} what it implies about Kirk.]]]]

* Averted in Alfred Bester's ''The Deceivers''. Titular Deceivers are a race of shapeshifters able to assume practically any organic form, but only of the same gender as them.
* Used as a major plot point in ''Literature/SteelBeach'' by John Varley. Humans have become effectively immortal, but body-changing technology is common and easy, if not terribly inexpensive. The main character, Hilde, realizes he needs a change of pace and turns female partway through the book.
* Elves in ''The Hound and the Falcon'' generally do have a gender identity, but most of them have no problem with taking on a form of the opposite gender. The protagonist, who was [[RaisedByNatives raised by humans]], finds this squicky but can't come up with a good reason why (and his love interest suggests that he just needs to spend some time as a girl).
%%* Happens all the time in the [[Literature/TheCulture Culture]] books.

* In ''Literature/ASongOfIceAndFire,'' Varamyr Six-Skins, a warg (able to control and possess animals), has experimented with inhabiting the bodies of both male and female wolves while they mate, just to see what it's like. His warging mentor told him that such things were an "abomination", but Varamyr didn't have much use for his rules.
* In ''[[Literature/WaxAndWayne Bands of Mourning]]'', the shapeshifter [=MeLaan=] reminds people in no uncertain terms that she is not bound to the narrow human mores of biology:
-->'''[=MeLaan=]:''' Small breasts? Large breasts? ''Extra''-large breasts? Picking a bust size is vital to a lady's evening preparations!' ''[later]'' I solved the problem. I'll go as a fellow... Um, is this a problem?
* In ''[[Literature/{{Patternist}} Wild Seed]]'', the immortal shapeshifter and healer Anyanwu was born female and thinks of herself as such, but her ability to transform her body includes the ability to change her sex. At one point, she tells another character that she can indeed father children, but only girls; it's implied that she learned this through experience, but the details are left to the reader's imagination.

** Though she appears female to most of the characters, Camille can also take male form if the viewer prefers--the Cat sees himself as [[{{Narcissist}} his ideal mate]]. She later notes that her species is actually androgynous.
* ''Series/{{Supernatural}}'': Played with in an episode where a Siren is seducing and murdering various guys "she" meets at a strip club, where she is, of course, impersonating one of the girls. Later on, evidence seems to point towards it having assumed the form of a medical pathologist to seduce Sam, when in fact it has assumed the male form of [[spoiler:an FBI agent]] to enthrall Dean. Not because Dean is bi-curious or anything, but because the Siren doesn't just limit itself to ''sexual'' desire. What Dean really wanted was a brother figure he could see eye to eye with.

** OlderThanFeudalism: As a trope involving shapeshifting and sex, Zeus ([[DoubleStandardRapeDivineOnMortal GOD OF HORNDOGS]]!) naturally gets in on the action -- with a twist. Most of the time, when Zeus decided to shapeshift in order to bang someone he found attractive (male or female, with or without permission), it was in the form of a male. However, when Callisto caught his eye, he was much chagrined to find that she had taken a vow of chastity in order to serve Artemis. However, he noticed that the vow of chastity left a loophole in that she ''could'' have sex with Artemis. Naturally, Zeus changed himself to look just like his huntress-goddess daughter, and had his way with Callisto. Somehow this got her pregnant, which, long story short, [[JustSoStory is why Ursa Major and Ursa Minor look like long-tailed bears, and also why (the Greeks thought) there are werewolves]].
** From the same mythology dept., the (not-yet {{blind seer}}) Tiresias (though he was no "natural" shapeshifter -- he killed the female of a pair of snakes having sex, and got turned into a female. 100 points if you find out how he turned back without using Wikipedia).
*** Another version has Tiresias get turned into a woman by Athena when he saw her naked (but recognizing it wasn't done intentionally, she only turned him into a woman rather than kill him). Later, Hera and Zeus decided to ask Tiresias whether he'd gotten more enjoyment out of sex as a man or a woman. Hera blinded him for siding with Zeus, so Zeus gave him the gift of prophecy to make up for it.
* Myth/NorseMythology: OlderThanPrint: Loki, Norse god of [[TricksterGod mischief]], is a shapeshifter. He was born a male, and two different goddesses have borne some of his children. By the giantess Angrboda, he sired the elder wolf Fenrir, the world snake Jormungand, and the half-dead Goddess of the Norse land of the dead, Hel. By the Aesir Sigyn, he had two sons: Nari (and/or Narfi), and Vali. In the form of a mare he also bore the eight legged horse Sleipnir, fathered by an actual horse. In one story, Odin accuses Loki of having spent several years living on Midgard as a human woman, including birthing several children. This is after Loki has just insulted everyone else present, so whether it is true or just Odin giving some payback is uncertain, but it was certainly deemed ''plausible''. Even more interesting, Loki shoots back by claiming that Odin had done the same. Since at least one other saga alludes to this, it is possible that there were now-lost legends that tell about both of these stories.
* Some versions of HornyDevils steal men's seed as feminine succubi, and implant it in women as masculine incubi. The resulting child thus has both a human mother and father, but you just know it isn't going to turn out right with a conception story like that...

** TabletopGame/{{Eberron}}'s Changelings also display this. The Becomers, in particular, tend to have very fluid gender identities and so freely indulge in both sexes and all sexualities as they see fit. Passers may be willing to change their specific appearance, but almost invariably have a very specific gender and sexuality they assume. Reality Passers, meanwhile, won't change out of their changeling form, but will happily shift between male, female, neuter and {{hermaphrodite}} genders as they will. It's part of Changeling biology to the point that, even though they do have [[ShapeshifterDefaultForm true genders]], alternate genders are fully functional, and even changelings with a "true gender" of male can become pregnant by using a female form.
** If playing in a campaign that permits dragon HalfHumanHybrid characters, this is probably how it happened. Sorcerers often claim to have dragon blood in their ancestry and some of them are actually right.
* Partially Inverted in ''TabletopGame/{{Rifts}}'', where Changeling [=NPCs=] (which are otherwise sexless) are often said to "Identify" with a single gender, which basically means that the forms they tend to change into will usually be only one sex unless they need to be the other.
* Lunars in ''TabletopGame/{{Exalted}}'' are often seen as being like this. Part of it is MemeticMutation, but there is at least one canonical Lunar who's been switching sexes on such a regular basis for so long that they now no longer either know or cares which they started out as.

** Ttranshumans can change bodies with only a little more effort than changing clothes (it's expensive and integration can take a while, but...). Gender identity is thus just that; it's quite likely that at some point you'll end up in a body of the other sex.
** Further, there's a Biomod called a "Sex Switch" which allows you to change the sex of the body you're currently inhabiting around at will (though it takes a couple of hours to change the genitalia on the fly) and you're not restricted to just "male" and "female," either, the game assumes there's a continuity.

* Averted in ''VideoGame/DragonAgeOrigins'', where it is implied that Morrigan stays female no matter what animal she happens to have turned into at the moment and can't take other human forms.

[[folder:Web Comics]]
* Sabine in ''Webcomic/TheOrderOfTheStick'' has apparently [[http://www.GiantITP.com/comics/oots0365.html tried it]].

** Ashley and Elliot are fairly willing to experiment with Elliot's shapeshifting magic. Ashley is bisexual, and has a bit of a transformation fetish. Elliot was born male, but is perfectly comfortable in female form. [[http://www.egscomics.com/index.php?id=2073 Their first kiss was girl on girl.]] Later on, Elliot's open-minded mother reminds Elliot that [[https://www.egscomics.com/comic/2017-11-03 lesbians don't need to worry about birth control.]]
* ''Webcomic/TheDragonDoctors'': Sarin, master of transformation magic, refers to herself as a "shapeshifting perv" but says that, despite this, she doesn't really have that much girl-on-girl experience.
* Elastic Man of ''Webcomic/EvilInc'', has no problem going either way. In fact, he's not certain if he has a gender.

* Jimmy T in the ''Literature/WhateleyUniverse'' can shift his shape to look like anyone or pretty much anything. By the end of Halloween, he has a boyfriend/girlfriend who changes gender on a cycle. Which means Jimmy would be changing his apparent gender whenever they date.

* WordOfGod has it that the [[TheFairFolk Third Race]] in ''WesternAnimation/{{Gargoyles}}'' have this kind of sexuality. They didn't start out with any concept of gender or sex, but they've "learned" about sexuality from humans, and can assume [[InterspeciesRomance whatever form]] they please. ''Gargoyles'' also treats the myth of Loki and Sleipnir (see above) as a true story. But then, Loki's one of the Third Race, too.
* In ''WesternAnimation/YoungJustice'', M'gann once turned into ComicBook/BlackCanary for a roleplaying make-out session with ComicBook/{{Superboy}}. The ''real'' ComicBook/BlackCanary was not pleased when she saw the security tape (neither was ComicBook/GreenArrow, until he saw the change, [[ActuallyPrettyFunny at which point he found it hilarious]]), though ComicBook/MartianManhunter tried to explain that this was a common "game" on Mars, since everybody's telepathy made [[BedTrick actual deception]] impossible. It's also worth noting that [[spoiler:her real Martian form looks like a huge, hulking beast by human standards]]. Superboy presumably prefers her standard Earth form, but [[spoiler:he already knew the truth before they hooked up anyway]].

** Grace was transformed into a male (and felt attraction to females) during much of her birthday party but [[http://egscomics.com/?date=2006-08-14 changed back to female]] when Tedd (at the time transformed into a female) got over his fear of liking a guy (however temporary that person was a guy) long enough to kiss her.

Some people might question [[NonHumanNonBinary what the normal concepts of gender and sexuality even mean to a shapeshifter]]. Others just find the idea that the cute girl they're flirting with is sometimes a guy [[ShapeshiftingSquick offputting]].

* In ''Manga/OnePiece'', [[WholesomeCrossdresser Bon-chan]] can assume the form of either a man or a woman thanks to his Clone-Clone powers. And Iva-chan can not only turn ''himself'' into a woman whenever he feels like it, he can change ''anyone's'' sex if he feels like it.

** In an early episode, Lister threatens to take an exam to get promoted above Rimmer, if Rimmer does not allow him to go on a date with the hologram of Kochanski. Paranoid that Lister will never switch him back on, Rimmer takes on Kochanski's appearance and initially claims "she" isn't interested. Once Lister realizes, however, Rimmer points out that "It's still her body", raising the question of exactly how far he'd go to avoid the situation.

* ''Series/{{Supernatural}}'': Played with in an episode where a Siren is seducing and murdering various guys "she" meets at a strip club, where she is, of course, impersonating one of the girls.

** Ashley and Elliot are fairly willing to experiment with Elliot's shapeshifting magic. Ashley is bisexual, and has a bit of a transformation fetish. Elliot was born male, but is perfectly comfortable in female form. [[http://www.egscomics.com/index.php?id=2073 Their first kiss was girl on girl.]]

This trope is for the confused sexuality of [[VoluntaryShapeshifting shapeshifters]] and the PowerPerversionPotential thereof. As many shapeshifters can [[SexShifter change sex]] willingly, they may [[JumpingTheGenderBarrier jump the gender barrier]] to accommodate a lover, or just for a change of pace. They may even be able to shift to a form which is [[NoBiologicalSex completely sexless]], [[{{Hermaphrodite}} or has facets of both sexes]]. Because of this, it's somewhat common for shapeshifters to be [[BiTheWay willing to get it on with either sex]], especially if [[TheMindIsAPlaythingOfTheBody their sexuality is tied to their current sex]].

** Slightly averted when she had to avoid a hug and kiss from Contessa de la Fontaine (Nick Fury's lover) while posing as Fury. Mystique had precisely copied his fingerprints, voice print, and retinal patterns to get past security, but if the Contessa hugged her, she would quickly notice that "Fury" was skin and bones, since Mystique didn't have enough body mass to duplicate all his muscles, and her abilities don't allow her to create or assimilate extra tissue.
