I don’t think she ever did that. But when we were dating before I knew we would get married, I would take her skinny dipping with my buddy and his girlfriend at night. My buddy didn’t marry his girlfriend, but years later knowing my buddy has seen my wife completely naked is a turn on. Better yet I know my wife saw his big cock but she has never said anything about it.
I did one when I was back in college as a non-traditional student. Most of the other contestants were traditional college age. I was ten years older, with kids almost their age. There were a bunch of guys who knew I was doing it and came to see, so I had a substantial cheering section. I ended up with second place. 1st and 3rd both 'met' the judges before the contest started.
It was fun, exciting, and a very validating ego boost that I maybe needed at the time..
