I had a good friend back in the 90s that lived close by. we hung out a lot. We were both young MSs in our 20s. He was married, I was not at the time. I had no idea how sexually "crazy" him and his wife were. One night we were sitting around and he 'joked' that he would let me have his wife for the evening. She was in the room too and smiled at me, Had I gone for it I'm %99 sure they were serious. We laughed off the awkward moment.
The previous week he was on stage giving his 2nd pub talk.
After the friendship faded away a few years later. I found out from my cousin, whoes dad was PO, that they had both been reproved for having a 3some, once with a girl, once with a guy.
All the while he was an MS giving parts and going out in service...he played the part well. Looking back now, I'm glad they had some fun.
No judgement here ;-)
