I'm (M) in a good relationship for just over a year. Sex with my partner (F) is great, but I have the fantasy of cheating in the back of my head. I have fantasies about her work friends, or joggers in the neighborhood, or coworkers I have now. I had one married coworker who'd frequently touch my arms and laughed at my bad jokes, signals through the roof, and the thought of her turns me on.

I guess it's not that I don't like the relationship I'm in, I just really enjoy the thought of casual sex on cheating terms. I did it several times years ago, and I still find the memory more erotic than most. Almost like a kink. Is cheating a kink? (outside of bull/hotwife situations, I know that's a thing but it's not what I'm referring to.)

I guess this post doesn't have a real point to it except that I'm curious how many men and women lurk on this sub with the same private fantasy in mind. Is it one you've shared with your partner? Have you also acted on it and how'd that go emotionally? And if so, what makes it so enticing to you?
