I think if the niche is too small, the website will not be very busy...unless you are looking for a date worldwide.

Might be a better advise to go to a nudist resort on holiday and try to meet someone.

The advantage would be:

- the weather is better
- wysiwyg
- it is easier to meet people on holidays then at home
- in some countries like France it is more normal to be naked at the beach and it is nothing special..also the number of young & attractive people might be higher the at some British nudist site for pensioners

A friend of mine used to work here:

its for women and families only. Single men are not allowed to enter the resort.

I have also heard something about Capd'Agne - a bit more bad - seems like they also have nudist nightclubs there.

Another one I met was working at some resort in the rainforst in Australia while doing a work&travel - she was working as a cleaner there (all nude LOL).
Can't remember the name, maybe it was:

I've never been a nudist but I kinda like the idea. Just being able to be totally free with yourself, have indepth conversations with the person opposite you (because you wouldn't be wondering what's under the shirt). I once remember at Glastonbury they had a nudist section and I heard that there was a lady in there sitting cross legged...hmmmm, not sure about that though!
