Agreed. Sometimes the drama that follows is just not worth the little bit of pleasure. I only sleep with girls I'm interested in for this very reason. If I'm not interested in the possibliity of a long term thing, then I just don't bother.
I have never had random sex and won't. I can't seperate sex and love. I have been with 5 people in my life. They were all solid relationships and people I cared very much about.
