When you're dating a guy, you can forgive him for some indiscretions, but it's nearly impossible to turn the other cheek if he strays. Well, Cosmo did some investigating to ascertain the traits that may make men more likely to cheat, and some of our findings were surprising eye-openers.

1. Is he a guy? Yes? Then expect him to wander all over the menu.
2. Does he still have testicles? Yes? What, you were expecting him to not check out the waitress?
3. See 1 and 2.

Thank you Cosmo for still more things that are useless.
