I do like yuri a bit as well (though I realize this community isn't about that either), though I personally can't handle futanari (the girls with male parts thing).
My favorite pairings are actually those between men who are friends (first pairing I ever got into was the still-unpopular Jet/Spike from Cowboy Bebop) rather than men who are enemies. (I understand the appeal of the latter, and it does make for some cool fanarts, but I still prefer the former).
In general I tend to prefer milder shounen-ai type stuff, though I have read some really good NC-17 fanfics so I'm staring to expand my mind a bit.
Hope it's OK that I'm here, I know I may not exactly fit in... I'm certainly not here to talk about anything that would offend anyone.
