I have finally come to the realization that the thought of my wife having sex with another man excites me. I thought I was insane and completely alone until I found this site and started reading some of the posts here. my fantasies about this are not as extreme as some of the other stories about this I have read, and I still have alot of fear about the aftermath. But I have masturbated many times thinking about the men my wife has been with before, and often times imagine them doing to her what I am doing while we are having sex. My feelings are unexplainable. I am jealous, angry, hurt but very excited and turned on at the same time. I told her to go with another man a few nights ago and she finally did. At first I was hurt, but I was actually getting aroused when she told me what she did. We have still not made the decision for her to do it in front of me, but I am starting to think more about it. We love each other very very much, but we enjoy unusual sex at times. Our sex life is wonderful, but this fantasy is growing more in my head by the day. I have watched her with women several times and it was great, but my wife is obviously more attracted to men. I don't know why I am so aroused at the thought of my wife having sex with other people. For those who have done this, did it strengthen your relationship or did it damage it? Any advice anyone can give me would be appreciated.
