Are men cheaters?

I over heard a couple of women talking about men, and the men who cheat!! First of all I do not believe that all men cheat on their mates, I for one do not, and I never will cheat on the love of my life for any reason, if you do cheat on your girl, you are a loser in the worst way! If you are unhappy in the relationship, get out, real men don't cheat!
