I've seen John Barrowman naked on the beach at Studland, Dorset UK - he was very well endowed although he didn't go naked all the time, but he changed on the beach and stood up naked taking a piss.

Also I used to go to a Spa in London attended by Damon Albarn - the lead singer of Blur. It was men only so everyone was naked most of the time - Damon used to walk around naked happily showing the fantastic meat between his legs.
