50 years the skin magazines were pretty tame by contemporary standards, hard core pornography was much harder to find, much more "underground". "Nudist" magazines and movies sort of bridged the gap, you got to see full frontal nudity but in a rather non erotic way, and it was done in a more "respectable" manner than exploitation movies. Of course this "documentary" shows only young, trim people, the girls are all fairly shapely, the men fairly athletic. (Obesity was much less common back then.)So you can take this one either way. A "documentary" extolling the virtues of the clothes-free lifestyle or an exploitation flick dressed up as an "educational" movie.
