So my wife 29 & my self 30 have been in a ENM relationship for about a year. She’s had a thing with one guy on and off for about a year… long story short is they never performed the act of sex but have been physically once or twice. I was physical with one female on a night out nothing consistent like her and this guy.

Well fast forward to now and she is back talking with this guy which side note I don’t really care for because him and my wife became almost like a couple when we (my wife and I) said that wasn’t what our relationship structure was going to be. Anyhow sexually me and my wife have been off like really off. So she asked me how I felt about her actually having sex with this guy to help maybe satisfy the sexual disconnect we are having. Much respect for her because she could easier just went and slept with him and never said a word to me so I respect it. My problem is the personally I’m unsure of how it will affect our marriage if they do. Only because I asked to do things strictly sexual and not build deep relationships with people and she declined. She said she needed to feel comfortable with a person which to a degree I understand/understood but now I feel like she’s using us as a copout in order to have sex with him.

I could honestly be overthinking it which I do often but the convo of making it a cuckold thing was brought up. I like it in porn but have never done it in real life. My wife is open to the idea but I don’t want us to try it and it make our sexual relationship worse. Has anyone experienced anything like this? Am I just overthinking the situation? Should I even be involved if they have sex? Side note we share encounter stories because we are best friends which now in hindsight was a bad idea.
