Psychology is crap! You cheat because you want to get off in some other gal, a new gal, a more exciting gal. Plain and simple. Acknowledging that you're a cheater doesn't win any awards around here. This is a good lesson for everyone out there: just because you fess up to bad behavior doesn't win any friends. Doing something about your wicked behavior does. Sounds to me that you're in the "I'm gonna screw any gal that says yes" phase...usually a college-age phase that one matures out of and then gets serious with the right woman. So, go out and get it out of your system...
