Re: I Was a Grade School Nudist, I've seen things that most people haven't seen.
This is a really good article, pointing out the standard mantra that nudity does not equal sex, but also pointing out that the secrecy that children of naturist families are asked to maintain is definitely not a good thing. It might be a necessary thing, but it is not a desirable thing.
The only way to combat this need is to normalize nudity, making the sight of naked people somehow more usual, less shocking, and more expected in certain situations. I think the best and most subtle and most effective way to support this trend is to introduce, re-introduce or continue to maintain the practice of completely changing into and out of sports gear and being sure to shower at spas and fitness facilities fully nude, and not later at home.
"Naked on the tundra" sounds a lot more romantic then it turns out to be...
