I used to "sleep around" before an MD friend scared me with information, mostly about herpes, I don't have an extremely large personal sample to draw conclusions from. My best memories are of partners with a physical feature that *may* have pre-disposed them towards sex. A great butt, great tits, or a great love canal. I also found "sluts" to be really good sexual partners. I once had a bad sexual experience and I think it scarred me for life. I grew very careful about partners and situations after that. Have you found any significant clues that a woman is going to **** your brains out?
