You have to do what works best for your marriage, for me,I had no problem sharing my wife, until she decided to go outside the marriage, and cuckold me with BBC. When we we having threesomes and I was included, I was fine. When she excluded me,I am not going to sit home while she goes out and has her fun. I cuckolded her right back for years with several women for her doing that to me,and while her flings lasted a few months, mine lasted years. My wife is very jealous and didn't take kindly to being cuckolded, and I made her pay more than she will ever know for cuckolding me. I would say if it is something that you can enjoy together that do so,but if not ,then I wouldn't go there, it may end the marriage.
