While we're all discussing sex and the exploration/denial thereof, I'd just like to say that I'd probably be more comfortable with my sexuality and my sexual desires would probably be more normal had my parents not instilled in me the notion that sex -- outside of marriage, in positions other than the missionary position, for reasons other than procreation -- was wrong and sinful.

I don't think I ever had a conversation with any parent that was even vaguely about sex.

So I have to ask... did your parents EXPLAIN different sexual positions to you? Was there a diagram of them, with all of them under big red X's except missionary?
