A friend of mine just got back from Europe. She said all of the people who SHOULD NOT be seen naked, were the ones with no clothes.
Probably the same with nude beaches.
Depends on where you go. Nude "beach" on the Rhine River? Bogus. Nude beach in Negril? Awesome.
I don't even want to look at myself nude! I can't imagine having to look at someone else as old and fat as me. ICK!
