Read their ad from top to bottom. If they continuously talk about sex and erotica, they are not "true nudists". Nudism is not about sex and erotica. This goes for women as well as men. If they answer your ad in a sexual manner, forget it. Read what they say about the nudist lifestyle. That should tell you something right away. Closet nudists don't count. Closet nudists are men who think they are nudists, because they walk around their house nude.
If you find someone interesting, and they are local and a nudist, meet them at YOUR nudist club. You'll feel safe because your friends are there .
Most nudist clubs are bit learly about letting in single men, so they interview and watch them the first time. If you are not a member of a nudist club, find one near you.
DO NOT get them into your nudist club as your guest if you have never met them. Let them pass the guest test first by having them get in on their own with a tour. The individual giving the tour will be able to determine if they can "welcome" them into club
FOR WOMEN NUDISTS, once they answer your ad, and they seem interesting to you, ask for their home number right away. Don't give them yours yet. Don't just accept an office phone number. They will either give you their cell phone or their home number. Cell phones are a little tricky, because some people don't have home phones - just cell phone.
DO NOT WASTE TIME EMAILING OR IMING BACK AND FORTH FOR A LONG PERIOD OF TIME. TALK TO THEM ON THE PHONE RIGHT AWAY. ALSO MAKE ARRANGEMENTS TO MEET WITHIN A FEW DAYS.
For women - When you are at a nudist resort or a nude beach, and he plunks himself on your towel without asking, he does not have manners and is not a considerate person.
If you are not meeting them in a nudist resort, meet them during the day in a well lit restaurant. NEVER NEVER let them come to your house before you meet them.
If they call you from a phone booth, that is a dead giveaway they are already taken.
