Men to women reatio
i'm not sure that more men are nudists....i go to local nude beach and it is totally full of men/women and all ages..i find that the younger people and especially women are just not into joining groups or don't feel the need to...the funny thing is if you look at nudist magazines the covers are always of pretty young women but the insides are full of pics of older men/women...just the way it is with most groups
in all nudist places where I have been I always found same numbers of men than women... maybe some times you can find more men because gay people love to spend a naked day around other nudists more than lesbian women... in the segregated gay areas of all nudist places always found more men than women... I think other reason it is because men enjoy more the "lanscape" in nudist places than women do
