I cant help u there as i live in england but there can be a similar problem here re single males being allowed into clubs but i think its harder now 4 clubs to discriminate against single males or anyone else. Also if it wasnt 4 single males naturism wud die. Good luck tho ok. - steve.
They allow single males at the Glen Eden resort in Corona, Ca, about 50-60 miles east of LA.
there's several gay nude guesthouses in Key West
