I'm one of those guys who enjoys nonsexual nudity, and its difficult to find in the USA.
I grew up in a household that was, I suppose, fairly pragmatic about nudity. If you were going to take a shower, you dropped trou and took a shower. There was no modesty in terms of using a towel between here and there. Leaving home, I went to school where guys took showers in a big "shower room." Any modesty I might have had was soon gone.
So, I get along well being naked with others. I've had a lot of great experiences overseas...such as the Rudas Baths in Budapest where guys walk around with a loin cloth that you are supposed to spin around to your ass when you sit down. Once its wet its completely see-through, not that it's meant to cover anything up...its really too small to cover much. I've been in saunas in Austria where swim suits are not allowed. Men and women are intended to enjoy the sauna together with only a towel to sit on. I've been in several ryokan (or "inns") in Japan, which have same-sex baths. You take a quick shower first then hop in the hot water with no fabric allowed. I'd love to visit a beach along the Mediterranean that is clothing-optional.
None of these places were sexual at the least, in fact, I travelled to all of them with a family member and it was good to rid him of any hang-ups he might have had about his body. The USA used to have lots of places for communal nudity...such as YMCAs, swimming holes, and public baths, but over time we have lost almost all of them except for sexually-oriented venues. Its good to know that other cultures around the world aren't so sexualized, and haven't developed the same kind of stigma as have many Americans.
