I spent 7 years in the BBC Sherlock fandom, and I never ran out of fic to read, and the variety was tremendous. Whatever kink you want, there's probably a bunch of it (and not for lack of purity wank, either).

More recently I've been into Peter/Tony. There are many antis, and they gnash their teeth on tumblr, but the people writing for this pairing must not give a fuck, because they post it anyway, and the kinky:non-kinky ratio is high.
