Don't like Shounen-Ai; love Yaoi.
True that Shounen-Ai beats around the bush a lot more - the fluff and innocent development's there if that's what people are after. But helluva a lot of Yaoi out there have way more plot than the softer love kinds I've read, so let's not diss out the genre before we've actually gotten to reading some good ones.
I don't like anything to do with an older guy and a hormonal-age boy (i.e. teen-ager to around twenty years old) either, but I could go with Lolicon. I'm a little screwed that way.
There's just something very very fun about it. I especially love pairings where in the manlier man has to bottom.
My favorite manga character of all time, in fact (and my current avatar), comes from a yaoi manga:
