I was one of these women who didn't think much of women that had one night stands. That changed when I had one! I've not had the necessity to do it again though..
He was considerably younger than me and he was great! Even with safe-sex.. I was impressed
I found it a very freeing experience.. you didn't have to worry about how you performed.. this person was never likely to see you again so whatever thoughts may have come from it didn't really matter. It really helped me to remember what sex was like and it can be fun. Just good sex for the sake of sex.
