I am developing a campground for nudists and have toyed with the idea of having the central lodge are for both men and women, but including smaller separate areas for each gender. Something like a pavilion with a small pool and sun deck down separate trails. Do you think that would be appealing?
It's a good idea, but maybe a little more difficult since it requires more infrastructure. Instead, you might consider having a central pool and sun deck, but having certain hours reserved for men-only and women-only attendance. That way, people could experiment with nudity only with members of their own gender, and gradually become more comfortable with mixed-gender nudity.
