the first time I shared my wife was with my best friend. we did it for years but after a while he did tell other friends. Some just asked and others would hang out late night hoping we would share. The ones that asked I told them we were not doing it with everyone and we never wanted it to be public. After that we did only did it with Strangers or people we know but outside our group of friends. Some of the guys didn't know I knew they were fucking my wife. We preferred married guys. They didn't talk to others about it.
