I have told other guys about my wife giving fucks to other men, but it was not because I felt submissive or needed to be humiliated. It is because I am pleased and proud and want others to understand my excitement over sharing "my" pussy with other men.
I also like to be in situations where one of the "other men" and I shock some third guy who is talking with us. After we talk and the third guy is genuinely confused, my wife-fucking buddy will turn to him and say, oh so casually, "I've fucked his wife", meaning me, of course.
I chime in and tell the third guy that it is true, and that this other guy has fucked my wife. The shocked look on the third guy's face is absolutely priceless, as he considers the truth of what he has just heard, from both of us.
Then when he recovers enough to ask me "Why?" I just tell him the truth, which is that my wife is a great fuck and that it makes me want to fuck her even more when I know that other guys are fucking her too!
To me, this is the very essence of wife-sharing. It always makes me want to fuck her just that much more, knowing that other men, including some of my close friends are using her naked body for their own sexual pleasure.
My advice, if you want it, is to find someone that you can tell. Say to someone "Other guys are fucking my wife!" You may be surprised to find how liberating it can be to use the exact words "they're fucking my wife!" or to say to some guy "Fuck my wife!"
