1) Nudity (as opposed to nakedness) is just fine. As near as I can tell your skin seems to prefer it. Visit White Thorn to confirm.
2) A long-ago friend, a connoisseur of the naked form, once said to me “You know, most people shouldn’t be nudists”. I understood his point, but I didn’t quite agree.
3) Watching people is fun, though for the most part they tend to be more interesting when they wear clothes they’ve chosen to flatter them in some interesting way. And then there’s what they say, which potentially will flatter them even more. (Caveat: it depends on your tastes.)
