Yaoi is the term the use in Japanese. (It's an acronym for no climax, no resolution, no meaning). I've been a fan of gay erotic fiction since I was fifteen as well. There's actually a convention in California called YaoiCon and it focuses on gay porn. (I'm going to be there in October! (if anyone cares ))
I used to think that maybe its the equivalent of straight guys liking lesbians, but as the genre is growing, I realize that perhaps gay erotic fiction has the potential to appeal to a larger audience. One of the main reasons why I like it is because it has a nice balance of sex and plot. Reading/watching porn without plot doesn't interest me. Maybe that's why most girls (I think) don't watch straight porn that much. It's all badly done. Gay erotic fiction, on the other hand, has the sensitive romance that girls like, but it also has the sensual and carnal aspect that women have been denied in the past.
The Japanese mangas and animes are very well done. Even my straight guy friends are willing to watch/read them because the plot is intriguing.
I'm not sure if I answered the question................
