This is really for men that want their wives to fuck other guys. If you think its wrong, go somewhere else. Even more important, if you think that, why are you on this site? Technically, your cheating on her right now.
My wife fucks other men from time to time. She can be a total slut when she wants to be. I have watched her fuck other guys and have heard her stories about cheating on me when she went out alone. She usually tells me everything eventually.
I can't get upset, because I have cheated on her too. I like to fuck married women, sometime secretly and other time with their husbands permission. A few times their husbands watched.
