Why is the word sex so taboo in nudism? If people don’t have a problem talking about sex and sexuality while clothed, then why is it such a no no when naked? Isn’t the idea of nudism is to simply be naked but otherwise everything else is exactly the same?

What do I do if I see a hot chick and my penis starts to have a mind of its own? What happens if I get an erection while at a nudist resort or nude beach?
