ALL MEN CHEAT?!

Has anyone else heard this? I'm not sure if it's just my age group or what but I am so sick of people mostly men saying all men cheat. Like some of my male friends, are always saying all men cheat. I don't think it's true at all, but maybe they mean at some point in their life a man will cheat? I don't know it just bothers me hearing it because it makes me give up hope in finding the right one.
