No. Naturists understand that you cannot shed years of socialization as soon as you arrive. Most clubs allow visitors to remain dressed at first. You may feel pressure to undress. That feeling is probably self-induced by the fact that you are the only fully dressed person within sight. Funny, isn't it, to be uncomfortable because you are dressed?

In most clubs, it is not appropriate to swim with a bathing suit. On naturist beaches, there is no expectation that you need to undress, since they are clothing- optional. If you are clothed and appear to be gawking you may be approached by others. Taking off your clothes helps allay suspicion.

Many large naturist resorts abroad are clothing optional - you can be nude or dressed as you please, but most places doesn't allow swimsuits in the pool and pool areas.

Nearly all Danish beaches are clothing optional. But some Danish naturist campingsites requires nudity on their bathing jetty.
