It's not always a question of would you let your wife having sex someone else, it's usually more of a question of what you can do to prevent her wanting to have sex with some well-hung guy behind your back. lol

If your wife knows a guy that's hung anything like this guy, she going to struggle to keep her panties on when he's around, could you really blame her for wanting him to make love to her?
