When we lived in Arizona, we'd often take day trips to deserted places and I enjoyed being able to be naked. As you said, ktsptksp, it's very liberating.
I'm not sure how I'd feel on a naked beach. I wouldn't mind not having a top. However, I don't think I'd be comfortable with no bottoms. Of course, I'm sure that if everyone is that way, it would become more comfortable after awhile.
I can imagine how nice it felt having the water, sun, and sand (well maybe not so much
) on a liberated nude body.
