This is a concern but I think it may depend on if she is just a hotwife or you are real cuckold, not sure what the difference is. But we did it yrs ago and fine now aside from almost no sex. But we are best friends and close. Maybe also depends on the rules and what she does with who?

My wife asked for an open marriage and we did this for a bit and we moved it to a hotwife one and one sided so only she played, is that which? But she didnt see single men or guys like me, most were types she never would marry, cheaters, etc. Helped to compartmentalize it and I never was there and we didnt do any of the humiliation stuff, was just sharing experience and she just had sex and came home.
