''Bokura no Hentai'' ("Our Perversion", "Our Abnormalities", or "Our Metamorphosis") is a seinen manga by Fumiko Fumi, based around three junior high school children who come across each other on a crossdressing community website and decide to meet up in real life. Marika Aoki (birth name, Yuuta) is transgender, Ryousuke "Yui" Kijima dresses up as his dead older sister, and Osamu "Parou" Tamura began crossdressing because the boy he liked wasn't into boys.

And no, it's not a {{Hentai}} (though it's not completely safe-for-work either). It also has absolutely nothing to do with ''Manga/{{Bokurano}}''. Also not to be confused with the actual {{Hentai}}, ''Bokura no Sex.''

It is completed at 10 volumes.
!!''Bokura No Hentai'' provides examples of:

* AbortedArc: Akane has her own troubles with growing up and her gender, but these are dropped without a real resolution mid-way through.
* AllLoveIsUnrequited: The main love triangle: Parou likes Ryou, who likes Marika, who likes Parou. Also, Hachi likes Ryou, Akane likes Parou, and Tomochi likes Marika.
* ArtShift: Marika's {{Imagine Spot}}s are drawn in an old-school shoujo style.
* ArtStyleDissonance: It has a very cute art style but the content itself is quite dark and adult.
* ArtisticLicenseBiology: The constitution of characters inexplicably becomes more feminine when they dressed like girls, which is especially noticeable in the legs of Yui. And that's not to mention the almost HalfIdenticalTwins resemblance of Ryosuke to his sister.
* AttractiveBentGender: All the protagonists.
* BeautyMark: Parou has one on the left (our right) side of his chin, and Tomochi has one in the middle of his right cheek.
* BiTheWay: Tomochi. He says he's mainly attracted to girls but doesn't seem to dislike the idea that he could fall for a guy some day. [[spoiler:In chapter 10, he flirts with Marika while seeing her as a boy at the time but later begins to see her as a girl and still flirts with her]].
* BitterSweetEnding: In a rather soft version, since despite the fact that [[spoiler: Marika [[EarnYourHappyEnding successfully undergoes the procedure for sex change and becomes attractive trans girl]] (moreover, she graduated from school being fully supported by her friends and classmates), and it is implied that Ryosuke starts from a pure leaf a romantic relationship with Hachi, Parou is still in a depressed-melancholic state and he are single.]]
* BookEnds: [[spoiler: Manga begins with three of our characters, who are embarrassed to meet for the first time at the store. It ends on scene, where they are young adults again meet in this place, already being free and happy people.]]
* CaughtWithYourPantsDown: Tamura in chapter 35.
* ADateWithRosiePalms: Marika takes a habit of this after [[spoiler:Parou molests her]]. She doesn't like the fact she does it though.
* DCupDistress: Hachi is shown to have this. She was OneOfTheBoys until she started growing breasts early. All her friends didn't want to hang out with her and her breast size was fussed over by boys and girls.
* DeadPersonConversation: Ryou has these with his sister's ghost… [[spoiler:Maybe?]]
* DeathOfAChild: The death of Ryousuke's middle schooler sister is what sent his mother into a SanitySlippage and is why he [[MySiblingWillLiveThroughMe crossdresses]].
* {{Deconstruction}}: A fairly brutal one of the OtokonokoGenre of anime and manga, pointing out every single little flaw with it, such as heavy transphobia and homophobia.
* DistantFinale: The final chapter leaps ahead five years from the previous chapters.
* DoesNotLikeMen: Mai, due to [[ParentWithNewParamour her family situation]].
* DoubleStandard: Sort of. When Akane complains in front of Marika that she dislikes being a girl and wants to be a boy, Ryou calls her insensitive. That Akane herself might be transgender is never considered.
* DudeLooksLikeALady: Ryou has been stated to look identical to his sister in elementary, just with shorter hair, and he has long eyelashes. It helps that, until a certain point in time, his sister was quite a tomboy and looked the part.
* DysfunctionJunction: Literally everyone in the manga has varying degrees of this.
* {{Expy}}: Marika looks and acts quite a bit like [[Manga/WanderingSon a certain other trans girl character]].
* ExtremeLibido: Tamura is a teenage boy who is depicted as overly sexual. It started out with erotic dreams of him as a nyphomaniac woman. It turns out his dreams were caused by [[spoiler:RepressedMemories of being being abused by an older neighbor boy while crossdressing.]] After Tamura broke off his sexual relationship with an abusive senpai, he began having casual sex with men and tries to bed with all the designated-male-at-birth characters. Even as an adult he's shown to still be this way but he isn't happy with it.
* FanDisservice: Almost all of the sexual scenes are this to varying degrees due to the characters ages and the situations themselves.
** The most sexual main character, Tamura, starts out in an abusive relationship with his crush and TheirFirstTime has him passing out due to pain.
** Tamura [[spoiler:molests Marika]] and this upsets their relationship.
** Marika's [[ADateWithRosiePalms sexual habits]] are portrayed as uncomfortable due to dysphoria.
** [[spoiler:Tamura tries to sleep with Marika and it's less dubiously consensual than before but the scene is still uncomfortable and Marika becomes scared before anything happens.]]
** The closest thing to fanservice, [[spoiler: when Ryou sleeps with Hacchi]], is still uncomfortable.
* FashionModel: Ryousuke's deceased sister was an up-and-coming teenage model. According to Ryou she was a huge {{tomboy}} for most of her childhood but took a GirlinessUpgrade when she became a model.
* GirlishPigtails: Ryou wears these when he crossdresses because his sister, Yui, used to wear them.
* GrowingUpSucks: Akane hates menstruation and Satoshi cannot fit into his sister's clothes, forcing him to stop crossdressing. Ryou worries about growing taller since he can no longer pretend to be his sister, Marika gets dysphoria over puberty, and Parou's crush thinks he's disgusting since he's getting more masculine. Hacchi's breast development has caused her much trouble, too.
* HalfIdenticalTwins: Implied with Ryousuke and Yui. They were in the same elementary class so they're the same age, and they look the part.
* IncompatibleOrientation:
** Parou and his love interest. It doesn't stop said love interest from exploiting him for sex so long as he's crossdressing, but even so, he's quick to dump poor Parou as soon as he starts looking too masculine for his tastes.
** In a ''much'' more twisted case, this applies to parou and Marika. Parou fell for Marika as a boy but due Marika only being a boy on the outside there's no chance of anything happening.
* ImportantHaircut:
** Ryousuke's mother has long, MessyHair at first but once she begins seeing a therapist she cuts it short.
** [[spoiler:Ryousuke]] cuts his hair after he quits crossdressing.
* InSeriesNickname: Quite a few.
** Osamu Tamura is "Parou", and he later gets the additional nickname "Tamurin" from Akane.
** Ryousuke Kijima is "Yui", taking his dead sister's name, and he's often referred to as "Ryou-chin" by his classmates and also gets called "Kiji" by Satoshi.
** Satoshi Natsume has the nickname "Tomochi".
** Ryou's girlfriend Miki Hachiya is usually called Hacchi.
* {{Jerkass}}: Ryou seems this at first, with his negative disposition and aggressive nature. He softens up afterwards, but he's still a very troubled kid all the same.
* LoveTriangle: One develops between the main protagonists. Marika likes Tamura even though she knows he doesn't feel the same, Parou grows to like Ryousuke but never shows it, and Ryousuke has feelings towards Marika that he can't really cope with.
* MaybeMagicMaybeMundane: It's unclear if [[spoiler: Ryou's sister was really a ghost, or if she was just his subconscious]].
* MoodWhiplash: The first chapter is rather sickly sweet with the second mostly being bittersweet, though Ryou comes along and gives a harsh foreshadowing to the grimness of the next two chapters. After that there's a constant bouncing between depressingly dark and happy fluff.
* MySiblingWillLiveThroughMe: Ryousuke's reason for crossdressing is that he pretends to be his deceased sister for his mothers sake.
* TheNicknamer: Akane.
* NoRomanticResolution: Other than MaybeEverAfter for [[spoiler:Ryou with Hacchi]], nobody is shown to end up with anyone.
* RapeAsBackstory: [[spoiler:Parou]] was sexually abused by an older boy when he was younger.
* SecretKeeper: Tamura, Ryousuke, and Marika from met on a site for crossdressers. Ryousuke is very adamant on keeping it a secret and even [[TongueTied originally threatened]] Marika over it. [[spoiler:Eventually Ryousuke's girlfriend learned about his crossdressing, learned [[MySiblingWillLiveThroughMe his reasons]], and got her parents involved because it was related to his mother's mental illness]]. Towards the end, Tamura and friends convince him to [[spoiler: enter a cross-dressing contest at school.]]
* SheIsNotMyGirlfriend: Ryousuke about Marika, on several occasions
* ShipperOnDeck: From what we saw of her, Ryousuke's grandmother is this for Ryousuke and Marika.
* ShoutOut: In chapter 3 to ''Manga/WanderingSon''. One of Ryou's friends has a crush on Marika and assumes she's a girl who crossdresses at school.
* SpotlightStealingSquad: Marika gets more focus than her two co-stars.
* TransEqualsGay: Despite the overall gay-friendly status of this work, she quite straight plays with this trope, portraying every crossdresser either as an obvious homosexual, or as having hidden bisexual inclinations.
* ThereAreNoTherapists:
** Ryou begins dressing up as his dead older sister and has delusions that she's a ghost speaking to him. His mother doesn't seem in very good shape either; their house is cluttered and she plays along with his dress up games. Parou and Marika aren't much better; the former is in an abusive relationship with a high schooler who only uses him for sex, and the latter has Gender Dysphoria and has suffered no end of transphobic bullying.
** Thankfully eventually averted as [[spoiler:Marika goes to a doctor to start transition and Ryou's mother is sent to the hospital for the mental care she so desperately needed.]]
* TheUnfavorite: Ryou's mother never cared much for him. She focused her attention on his older sister, who was an up-and-coming model before she died. Even after her death she only pays attention to him when he's dressed as her.
* WantedAGenderConformingChild:
** It's briefly shown in a flashback that Akane's mother was disappointed in her disliking skirts as a toddler.
** Subverted with Marika's mother. She takes to Marika coming out as trans without any disapproval.
* WholesomeCrossdresser: Ryou and Parou. Volume 2 introduces Satoshi, who goes to school in the girls uniform.
* WrongGenreSavvy: Marika seems to think she's in a classic {{shoujo}} manga. She isn't.
* YouGottaHaveBlueHair: Parou; although based on the dialogue, it's actually a stylised black.
