I think if I was looking for "relief sex", I could enjoy it. But I prefer a partner I know and can share more than a quickie fuck with so I can't see myself making a habit of it.
I’m married, and of course that’s somewhat of a different relationship than one that is just for pure physical and emotional fun. Marriage aside, I don’t see ANY reason to keep any other around for the long haul. There are just way way too many guys and too many experiences waiting out there to otherwise limit oneself. Of course not everyone is going to be deter than the one before, but such is everything in life. Variety surely is the spice of life!
