My wife (37f) and I (37m) have talked about this before. She didn’t say no but never brought it up again. I have a kink that I want to watch my wife with another guy and possibly join in with sharing her. She doesn’t seem that interested in it but she doesn’t seem against it either. We sometimes send sexy gifs to each other and I’ll sometimes send an occasional mfm one to her and she responds with a “mmmmm” or something. And just sends one regular sex one back. How can I bring it up to her again?
