The only naked men who flaunt themselves are solitary male "nudists" lurking in remote dunes known for pickup.
We were on a beach in spain last year where we were the only couple. My DH, bless him, really thought i was joking that the solitary males, wandering about pensively with no clothes on, were as it were trying to find a boyfriend. I hasten to say that they were not showing off any untoward signs of arousal - and they did have nice bodies.
But we have stripped off in remote areas or nudist beaches in Greece.
Once, in a remote cove I god "buzzed" by the Greek airforce, who kept going round in circles in their fighter jets (DH was in the sea at the time)
Another time I dragged the poor man off to a nudist spa experience in California.
On the cliff top in Big Sur lies the Esalen Institute. Birthplace of the personal growth movement. (personal growth has nothing to do with previous topic!)
You could go and get a massage there with the pacific waves crashing far below. I thougth this would be an unmissable californian experience.
Sulfur hot springs fed the hot tubs. DH was terrified "Jess! Jess! where are you going?" "I'm just going to the loo dear". But he cheered up when a big bosomed therapist chatted him up. The massage was fantastic (if expensive) and it took several days to get the smell of rotten eggs out of skin and hair. Could do without the sight of other mens dangly bits though, not a pretty sight.
