The English use of "hentai" is more similar to the way the Japanese use the slang term ecchi, which refers to any sexually explicit content or behaviour.
There are two main categories of hentai: works that feature mainly heterosexual interactions and those that feature mainly homosexual interactions.
This second group can be further split into yaoi and yuri subgroups. Yaoi refers to male homosexual pairings, and yuri to female homosexual pairings.
(Note that both yaoi and, to a lesser extent, yuri are predominantly aimed at members of the opposite sex from the persons depicted.)
