Clothes often force your body into shapes and positions that don't feel natural. Next time you've dressed yourself up to the nines, take a look in the mirror when you've taken it all off. Have a look at the crease marks around your waist from the belt that was too tight, or the deep gouges in your shoulders from your wonderbra, or the ribs around your shins from socks, and the redness of your little toes that have been squashed into fashion shoes. Nudity is the most natural thing in the world. We live in a society that has grown to view the human body as something to be covered - even ashamed of.
Naturism takes the opposite view.
It sees the human body as good, normal, varied - and something that only needs covering if the owner wants to cover it. There is nothing lewd, crude or distasteful about the unclothed body. Given that naturists are representative of the population as a whole, then it's entirely possible that we number an odd sex maniac amongst us. The law of averages makes it likely that there are also several fetishists, a healthy quota of gay men and lesbians, one or two celibates and a handful of free love exponents. For many people, the only time they are naked with another person is before, during and after a sexual experience.
