But in my case I am fine with my lover being with someone else at times. I do not want to watch or cuckold.
But do be honest and open.
I lived with a couple for nine months when I was in the Air Force. I loved both of them and we had a wonderful relationship. I was devastated when they were transferred back to the states and I was stuck in Europe for another 8 months. We were also swingers, and after they left I tried to have a similar relationship with another of the couples who were a part of our regular group. Unfortunately, while the wife had no problem with her husband having sex with other males when they attended swingers parties, she became very jealous of the relationship between me and her husband when I moved in with them and it ended rather badly.
