"Cheating" is different in every culture.
In Japan and Korea, almost every man cheats on his wife. Usually with whores, or they will be a sugar daddy to some hot young piece of ass.
It is not even considered unusual. It's just normal. Most women know their husbands do it, but they turn a blind eye to it because "That's just how men are."
In the USA you men have been whipped into place by the women. Feminism run amok. American guys have a very prudish attitude towards cheating. You all turn into a nuetered puppy when you get married. Must really suck to be half a man.
