hmm, this doesn't bring me "real" pleasure but I do, however, feel rather guilty whilst at it:
I'm not into yaoi or furry porn but I'm extremely fascinated by the fact that some people are (seriously, I come across very, ah, suggestive drawings and stuff done by 13-year-old girls almost on a daily basis - I didn't even know such things existed when I was 13 ._.) and so I sometimes like to do some, err, research. If my mon ever caught me browsing through those galleries I'll die before I get the chance to explain.
Something that does make me feel both pleasure and guilt, though: EATING RAW BACON.
