The Oxford Dictionary Online defines it as "a subgenre of the Japanese genres of manga and anime, characterized by overtly sexualized characters and sexually explicit images and plots." The origin of the word in English is unknown, but AnimeNation's John Oppliger points to the early 1990s, when a Dirty Pair erotic doujinshi (self-published work) titled H-Bomb was released, and when many websites sold access to images culled from Japanese erotic visual novels and games. Hentai is defined differently in English. Usage of the term hentai does not define a genre in Japan.
Less official terms also in use include ero anime ( エロアニメ), ero manga ( エロ漫画), and the English initialism AV (for "adult video").
: 100 Japanese pornographic works are often simply tagged as 18-kin ( 18禁, "18-prohibited"), meaning "prohibited to those not yet 18 years old", and seijin manga ( 成人漫画, "adult manga"). : 99 While the term has expanded in use to cover a range of publications including homosexual publications, : 107 it remains primarily a heterosexual term, as terms indicating homosexuality entered Japan as foreign words. The character hen is catch-all for queerness as a peculiarity-it does not carry an explicit sexual reference. In sexual contexts, it carries additional meanings of " perversion" or "abnormality", especially when used as an adjective : 99 in these uses, it is the shortened form of the phrase hentai seiyoku ( 変態性欲) which means "sexual perversion". Hentai is a kanji compound of 変 ( hen 'change' or 'weird') and 態 ( tai 'appearance' or 'condition'), and means "metamorphosis" or "transformation". 7 min 93% Hot and Wild Gay Bareback Fucking 5 min 97% Awesome Hardcore Gay BareBack Anal Fuck 7 min 76% HD Nice White Gays Hardcore Fucking 2 min 99% HD BIG DICK CREAM IN TWINKS ASS ANAL CREAMPIE 7 min 89% Bottom twink barebacked after blowing cock 5 min 82% College Gay Dudes Hardcore Bareback Fuck 5 min 100% Extreme Gay Bareback Fucking with Cum Blast in. 8 min 100% Hot Latin Gay Extreme Hard Barebacking 5 min 91% Bareback Gays Loves to Fuck hardcore in the Ass 7 min 100% Horny Gay Fucking Tight Hole 21 min 97% Gay (gas) Station sex 7 min 80% Gay Couple Bareback Fucking 5 min 100% Hot Gay Couple Barebacking Action 10 min 100% Sweet Gay Cock Sucking and Anal Fucking 5 min 93% Hot Gay Ass Pounding With Messy Cumshot 5 min 100% Gay Loves Fucking Bareback In the Ass and Cum 7 min 91% Hot gays loves licking dick and anal sex 7 min 96% Steamy Bareback Sex With Latino Gay 7 min 100% Hot Beefy Action Pounding Fuck in the Garage 5 min 100% Sexy Gays Having Nasty Bareback Sex 7 min 98% Hot Gay Bareback Fucking With Cumshots 4 min 100% De nuevo cogiendo con este señor. 7 min 98% Hottest Gay Hardcore Bareback Anal Sex 7 min 100% Hot Gay Bareback Anal Sex 8 min 99% Horny Gay Jock Lovers Amazing Bareback Fucking 7 min 100% College Gay Studs Extreme Bareback Anal Fuck 5 min 82% Barebacking Gays Tight Hole on a Red Couch 5 min 100% Gay Anal Bareback Fuck and Nasty Cumshot 5 min 95% HD Blond straight boy on gay casting 5 min 100% Sexy Gay Caught Having Tight Ass Bareback Fuck 7 min 100% Bareback Gaymen on Hardcore Anal Fucking Action 5 min 92% Steamy Gay Ass Fucked Hard With Nasty Cum 7 min 100% Hot Gay Bareback Fucking With Cumshots 7 min 100% My Hot Gay Neighbor In Nasty Bareback Fucking S.
