We were in our early 30's at the time. We had already been together over 10 years and she caught me screwing a woman that I met through personal ad in an alternative newspaper. The affair was about mild dominance and submission.This was in the 80's long before the internet.

We had a long talk. It turned that she had a couple of affairs. One affair with a co worker and another a one time hook up while out at a bar with her girlfriends. I confessed that I had dominant fantasies all my life since I was a boy and that I had no idea where those desires came from but they would never go away. I said that my fantasies included non consent, spanking and women who were submissive. Fairly mild stuff in my opinion.
