I'm a bit of a pain slut.
I love restraints (cuffs - preferably leather, rope, hell, use your hands if you're strong enough!), I love biting, slapping, hair pulling, rough penetration (especially rough anal), name calling.
I can get off on "normal" sex, and absolutely love it, but it's the rough stuff that really gets me going. It's amazing how many guys just aren't into it (or have been raised with the mentality that this kind of behaviour is wrong, even if it's consenting).
I like to push myself, and I've only ever been with two guys who have *really* taken that leap and been open to experimentation.
I like to watch *very* rough gang bangs (one girl 4+ men), and they are the subject of many of my fantasies. I am not ready to be in one, however.
