My wife and I have been playing around with the idea of ENM, mostly FFM and MFM threesomes. While we agree we both share the fantasy and we both want to enjoy this experience together, we both also agree that we don't have any real desire to sleep with others. My wife and I have been monogamous for 17 years. Before her, I had never been with anyone else, she's had partners prior.

Sometimes, the idea of threesomes make me uncomfortable, I'm not sure if it's anxieties over something new or because I think ENM isn't what's right for me. I definitely entangle sex and love and worry that sex with others will somehow change how i view sex between my wife an I.

I also have anxieties over experiencing something new and wanting more, like tortilla chips, you can't just have one. This worries me because our sex life, while not our relationships foundation, it's definitely an important aspect. Will that to change?

Thought?
