Heavycum,.....I don't think this is something you really need to worry yourself about,...for now, just get your eyes tested and find a decent dictionary and everything will fall into place over the next few years.

True naturisam is not about sex at all!!!! It is about being comfortable being nude and accepting your self as you are naturally!If your at a nudist resort it is not polite to stare at all. Most TRUE nudists dont have the problem of being hard arund others that are nude also.
Dont get me wrong the inevatable erection is apt to happen at some time, the best thing to do in that case would be to cover it up with a towle.Nudist ediquet is to always have a towle handy for that reason and for sitting pourposes,no one likes to sit naked with out a towle.
Best solution is to keep your sexual feelings behind closed doors if you dont want to be asked to leave.
I'm talking about nudist resorts and camp grounds,Hedionisam is something entirely different.
I know I was a manager of a nudist resoret for 4 years!
