Is it okay if I just sit and watch others hang out naked even though I am not undressed?

I have never been naked around other people at either a nudist resort or nude beach. When I decide to go my first time, do I have to take everything off? I’m not so sure if I can do that right away.

Do I go with it or politely tell them that’s not appropriate here?

We are human right? Well that’s not my question but it leads up to one that I am wondering… What should I do if someone says a flirty comment? In response to that should I just go with it or politely tell them that’s not appropriate here? I am not aware of how to handle such a situation.

Sometimes I find it difficult as a man to control certain body organs. If I get an erection at a nudist resort, will I find myself getting kicked out of the club?

Whenever I get naked with a boy, I try to be certain to shave my pubic region. Will I need to keep on top of this if I become a nudist? I hope not, that can be too much maintenance.
