Amos-Most figures I've heard are that one woman in three is raped at some point in their life. Many of them never report it, so I'm not at all be surprised that your friends didn't tell you-they might not even admit it to themselves. As far as socio-economic distribution goes, I think you'll find (though this is just a hunch) that domestic violence is much less dependent on class than any other kind of crime.

Little Hawk-I'm more disturbed by the extremely prevalent Japanese Lolita complex than any other of their sexual fetishes. S&M is alright between two consenting adults, but pedophilia is another matter entirely.
