RE:naked and exposed
I think at the beach it may initially have been excitement, a bit naughty, the chance for me as a young man to see naked women etc. But soon you get really comfortable being nude at the beach and swimming that way becomes the only way. Walking naked on the beach in the sun is great too. Have had a few skinny dip nights in pools when drinking with friends but that is often a first for some, and a once only. I find I'm comfortable this way and don't care if I'm seen, it's natural.
