I am the same, RATTER.
I have had one night stands in the past and to be honest I don't see much wrong with them ~ as long as the couple are happy with it! unfortunately in most cases one or the other wants a relationship out of it.
I can't remember the quickest time from meeting to having sex, maybe because it isn't something I think about anymore. Even though I already knew Mr P as a friend for about 20 odd years we slept together on our 'first date'. I guess it was about 7 hours into it...lol.
