Okay, so this is a guilty pleasure of mine - BL/yaoi/shounen-ai/whateveryouwannacallit. I suppose this stems from the fact that I've never really liked female characters (with only a few exceptions) - they always seem so unnecessary. So when I started getting into the Gundam Wing fandom around the age of 14/15, it dawned upon me, what with all the slashfics out there, that the female characters could simply be taken out of the equation...or at least, be removed from the spotlight.
After having discovered fanwork with BL themes, I began to branch out into series in which BL was canon. Actually, this only really started a couple of years ago when I found a pic of Kau (Togainu) in a thread on /y/. By the way boys and girls, never go to that place, it's full of unsavoury characters. xD So I guess you could say I'm something of a newb when it comes to BL?
Anyway, here are the few BL-related works I've seen/read/played for myself. No doubt this list will grow in time.
1. Togainu no Chi (Visual novel/manga/anime)
Ah, TnC. I think the reason why I didn't read/watch/play BL stuff for a while was because I thought it was all sappy love stories where the artist could've used a girl instead of the uke, but decided to use the uke because it's that much cooler. Then I played this. It was good - the plot was interesting but not so complex that I couldn't understand anything at all (since I don't understand much Japanese to begin with p:), although I laughed at the predictable 'everything invariably leads to sex' thing. But you know how you can tell if a BL plot is good or not? Take out the buttsex and see how it goes - they've turned it into a manga and anime, and even an alternate game, all without the BL in it, and it's still a good story. :3
Still, no matter what version I play/watch/read, Keisuke always scares the hell out of me.
