Yes. Lots…
As a teenager strip poker and dares afterwards that ended with me running round a block naked.
Then skinny dipping and being the only to take off my underwear.
As a student .
First time i was a life model.
It was a photographer’s evening workshop, once uI turnedp I had no choice to be naked for four hours in front of seven clothed artists. I didn’t know I was suppose to bring a gown, so even in the breaks and trip to the toilet a 50m down the hallway.
Also advertised as a naked cleaner on gumtree, so again second I arrived and knocked on the door, I was obligated to go naked.
Also a game of dares on a student night that ended me walking naked to our student flat for two miles.
