Women seem more reluctant to go nude.

When I first started researching the subject I had the idea that the reason was because women would feel threatened or become the focus of unwanted attention, but direct experience shows that naturist venues feel safe and welcoming to women. It seems the real reason that women may not join is that many fear they are not "up to standard". This is an enormous shame, a symptom of the damage done by the relentless selling of the elusive image of the perfect body. The experience of millions of naturists has shown that it helps to free people from a poor body image. If nothing else, experiencing social nudity shows that most people have a body far from perfect and that it does not matter a jot. A great deal of advertising in the Western world is concerned with the quest for beauty and this is mostly aimed at women. The implication is that if you do not spend on beauty products, you will be a lesser person. This leads many women to undervalue themselves as people. Looks have nothing to do with naturism, people do not do it to be seen nor indeed to see others, they do it because it feels good. Fashion and the hunt for the perfect body only leads to dissatisfaction, this perfection is not achievable. Sadly, many women seem to feel that if they went nude, their long sought "look" will vanish.
Fear of sex related crime has been cited by a few as a reason they would not go naked in a social setting, but it comes as a surprise to them that there are much lower rates of sex related crime in naturist communities. Their prejudice tells them nudity "must" cause sexual stimulation and will therefore lead to all sorts of lewd behaviour. The experience of millions shows it doesn't. When the naturist centre at le Cap d'Agde first opened, the local police took a close interest but experience over the years has shown this to be unnecessary. They are better employed elsewhere.
