Secret Sex! Do We Really Have Them?

I was just watching an older episode of Sex in the City, which by the way I got a lot of silly ideas about secret partners and sex. I by no means am an expect on men but I do have common sense and intuition that saves the day. It seems that till this day we have sex with people that are so ugly but have the most wonderful sex that we are so ashamed to introduce them to friends and family. I know everyone has gone that path once in their lives. I personally have had done that one or maybe twice. I was so young that I don't remember  with whom or where but it had happen. I couldn't even tell you there names because they where so freaken ugly that I couldn't associate them with anything not even the great sex. I know that you can easily find your self in a situation like that but what runs through mind and what do you tell your self? I wonder whatever happen to those people too. It's amazing the things you think of sometimes.
