I'm amused that Tenchu is horrified by the idea of Draco and Harry getting jiggy but not Inu-yasha bumping uglies with his own brother. Or did you not notice that bit?

Eh, Nyororin is right- girls just like guy-on-guy for basically the same reason guys like girl-on-girl; it's entirely detached from issues of homosexuality so please don't start on the whole "but fags are gross and unnatural, ewww!' argument, because yaoi doesn't go anywhere near portraying realistic homosexual relationships and most of the fans are heterosexual women.

Think of it this way; if a woman watches heterosexual porn she is almost always implicitly forced to empathize with the female character. In yaoi, the viewer can empathize with either character as they wish. There's a reason a lot of yaoi male characters are feminized; it's not about obsessing over what real homosexuals do, it's about allowing women's mental attitudes towards sex to be flexible.

It's also emotional. Yaoi dudes express their feelings, or if they don't there's a big reason why. So in that respect it can be something of a female fantasy fulfillment; a man who connects emotionally with relationships and sex and shows it.

Amongst other reasons of course. Some girls just don't like seeing vag in their porn when they can have two helpings of man. Fair enough, I say, let them eat cake.
