As others have said, real world naturist parks have more women than online naturist forums. Women are getting heavily involved in social networking sites like Myspace, Facebook, Twitter, and the dating sites, but the rest of the Internet is still dominated by men. Still, let's admit that women in the US are not raised with as much nudity and body acceptance as men. But in recent years, women's beach swim wear is closer to nudity what men generally wear and yet it tends to be for the wrong reasons. While I can understand the desire to celebrate having a young beautiful body by baring most or all of it, don't we also want to give people "permission" to be nude simply because it is natural, practical and comfortable regardless of our state of physical perfection or imperfection? Because of some basic differences between the sexes, women may always be slightly more conscious of their appearance than men on average, but can't we at least work toward the day that most women will let desire for the comfort of nudity override their self-consciousness and join us in equal numbers on the clothing optional beach?
From the hips down, the typical bikini bottom reveals more than the typical shorts a man wears to the beach these days. But there is understandably great resistance to peeling off that last little bit of fabric and meeting the public with nothing covering nipples, rump and genitals. Unfortunately, our culture teaches men and women that body parts that are true organs of procreation must NEVER be seen; there is the notion that covering these parts provides psychological protection against unwanted sexual attention. Popular culture has socialized many women in America to reveal some of their body to attract a mate, but also told that total nudity is too "loud" a sexual invitation.
Another part of the problem is that of body image. Even young attractive women often lack confidence in their bodies and women who show signs of aging even more so. For those women with the confidence to bare most or all of their bodies, there remains the hurdle of the treatment they receive on public and clothing optional beaches. Specifically, the staring and even harassment that young women get on clothing optional beaches may lead them not to come back to that beach again.
Another problem is that the nudist community lives in secrecy, still timid after years of persecution by mainstream society. So how will people learn about nude living if our communities are so seldom heard from? And lastly, the fact that deviant sex groups, swingers and the like usurp the terms naturist and nudist when describing their events and true family naturism gets tainted by association. But to be honest, naturist organizations have not done enough to isolate their member resorts that have allowed or even promoted sexually-charged events. Women have always been more vulnerable to sexual intimidation than men and even more disinclined to visit a mostly family-friendly resort that has a few bad eggs.
I am preaching to the choir for the most part, but there may be some newcomers here who would appreciate these general observations. Hope it helps!
