Cheatfest guys vs girls?

What is with the common misconception that guys cheat more than girls? I've had 4 ex's that all became ex's because they cheated, my friends all great gents also had their burns when their girlfriends cheated on them. I'm currently in a happy and hopefully long term relationship (longer than the others so far) but im always waiting for the cheat to jump up and bite me in the *** again. Let's broaden the boundries for cheating, flirting counts, hugs with hand on ***, "love" used too freely in texts etc they all count, then the whammy of kissing and doing the nasty. I've got friends who yes, have cheated on their girls, but only cos of their "jock and pretty boy" mentallity, they know they're all that so they flaunt it and all grab all the girls with no morals (ie most girls). Show me one girl please that wouldnt jump into the arms of a brad pitt wanabe and leave the caring and thoughtful comforts of a nice guy maybe not the best looking but more compionate than your everyday jock...
