My wife is her own person. She is not my property. I do not barter her for sex with other women.
If another woman doesn't want to fuck me, and the only reason she is there is because she is in some sort of trade, I don't want to fuck her.
I want my wife to be herself and enjoy herself. If that means I have to not fuck other women, so be it. It is also the other way. If she doesn't find a guy she likes and I find lots of women . . . well, she is ok with that.
While this works for us, it may not work for you. This is our belief system.
