One guy is more than enough for me so I've not felt the need to cheat, but I do think women are less prone to cheating than men "overall" based on various biological and social issues.
As a bisexual female (since I was old enough to be any kind of sexual, and now I'm 30 so I'm not exactly sowing wild oats anymore)... I do feel the urge to hook up with a girl now and again. This is a huge plus for my guy (of course) and he has always said that if he met a girl in a bar that was coming on to him he would call and ask if he could bring her home... and I would most likely say yes.
