I think there are probably a lot of guys who bring it up because they get off on the idea but don't expect their wife to act on it. Then when she does they can't handle it and get angry. I just think it's unfair to do that and then blame the wife when she's only doing what her husband said he wanted.If a guy can;t handle you fulfilling his fantasy for him, that;s really his problem and he then has to learn to deal with his feelings, you on the other hand now have a free hand to fuck any guy you want, it was after all him that set you free to fuck other guys
Some men can be jerks that way. I've even had guys I've been fucking get upset when they found out I was fucking other men ffs. If I was screwing around with them, why would that mean I wasn't doing the same with other guys. Some men just have fragile egos lol
