I find that wearing nothing in the warm weather makes me sweat a lot less and therefore saves on both washing of clothes and washing of me, a quick water saving shower is all I need and I'm fresh n clean!
I do shave my pubic hair and have done for years now since I observed clean shaven men and women on nude beaches and resorts in France some years ago, I prefer the smooth feeling and look and find I am less sweaty down there!
There is a website for information on hair removal for both women and men at http://www.wnn.nu/ and although of course its a very personal thing I find that a lot of both sexes are now trimming or totally removing their pubic hair, to be a nudest nudist!
I have absolutely no hangups about my body (although I would prefer a trimmer tum!), and who sees it, although I try and respect the feelings(which I find difficult to understand) of those that are embarrassed at the sight of an unclothed fellow human being!
