Hey all. When I find myself sleeping with one girl for a while, I have this desire to sleep with another woman. When I do, I really get back into the old girl and my sex drive with her goes through the roof. I often find myself "cheating" on a girl to better our sex lives. Now I don't really consider it cheating cause I only do this with girls that I'm dating, not on a girl friend or anything. Although we never actually say it, it's assumed by girls that I could very well be sleeping with someone else. So my question is, can anyone else relate to this sort of primal urge? I'm only 20 so maybe this is just a stage I'm going through. Can anyone else relate to these urges? And I don't mean "do you ever feel like sleeping with someone else?" I mean that you have to sleep with someone else in order to want to sleep with your current girl again? It's fucked up but I figured I could ask here, thanks!
