I would like to thank everyone for all the great replies and comments on this topic. Your comments were very interesting and insightful. Telling Mrs. Swing about my past cheating was not something I was considering until recently. We have been married for 8 years years. Our relationship has went though many changes over that time and especially in the last six months since we got into the lifestyle. We now talk and communicate like we have never before. I wanted to tell her about my past transgressions, but I wanted to pick the right time. Mrs. Swing is quite an unconventional woman in many ways and she continues to surprise me year after year. In the past I never thought she would consider swinging, I just did not think she had it in her. But she totally surprised me and now she is as enthusiastic about as I am.
I actaully did tell her about my past cheating. The moment in which I told her about was not planned, it was a spur of the moment decision based on circumstances. Mrs Swing and I were having a discussion about secrets we kept from each other. Mrs Swing had figured in the the past that I might of done something, but I never would admit to it before. During our discussion Mrs Swing invited me to tell her if I had ever had cheated on her. So I proceeded to tell her, my gut feel was that this was the time to tell her all the details. I mean why not? I did tell her the details and her reaction was not what most would expect. Mrs. Swing still was not exactly impressed with my cheating, but her response did not exhibit the hurt and anger that probably would have been the case six months ago.
We discussed the details for several days and the end result was that our relationship is stronger now than before. Our discussions gave her greater insight into who I am why I did it. There is certainly no need for anyone to cheat now since we are in the lifestyle and being honest with her about my past really helps to for me to honest with her in the future.
