Thanks for your reply, Leah.

I've thought this over and I've decided I have a healthy attitude toward sex, including a caring mom's natural feeling of a small bit of curiosity about my little boy turning into a man. My son is open about talking appropriately about sexuality, which has been a little shocking to me sometimes (though I just listen to him and certainly don't show my surprise...done a lot as a parent, lol). He's a successful young man with a wonderful respect for the women in his life and I'm sooo glad of that.

Frankly, I find it very hard to believe that everyone, or most everyone, doesn't have a fleeting thought now and then about the sexual behavior of friends, family, whomever. If the thoughts aren't conscious, I'm guessing they remain repressed within the unconscious and might show up in dreams, for example.
