Summarize:

There are many rules to follow when you are visiting a nudist area. Some are unwritten, but some are explicitly stated. Think about things that would make you uncomfortable while you are sunbathing nude. Then avoid doing those things. Pay attention to the behavior of others, and conform to social niceties.  Some nudist resorts are adults only. If it doesn't specifically say that in the site's promotional materials, feel free to inquire. If you want your children to visit a nude beach, find an area that is kid friendly. This is much more common in Europe than it is in the United States. Avoid staring at others. No one likes to be gawked at. Pay attention to yourself, and those you came with. Don't make the situation sexual. Nudists are there because they embrace the freedom of the lifestyle, not because they are seeking a romantic encounter. Don't be an exhibitionist. This means not engaging in any sexual activity in front of others, or engaging in any physical acts that could be considered lewd. Many people cite growing confidence as one of the major benefits of nudism. Even though it might be uncomfortable your first time, try to be confident in your own skin. You will soon realize that nudism isn't about looking a certain way--it is about feeling at ease. No one expects you to have a perfect body, so just feel good about what you have. Give yourself a pep talk before stripping down. Think of your favorite part of yourself and concentrate on that. Are your legs strong from doing a lot of walking lately? Let that be your focus. One of the main components of the nudist community is acceptance. You don't want to be judged by others, so make sure to practice that same mindset. Avoid thinking about people's physical attributes and instead focus on your own experience. Go into this knowing that you will see all types of bodies. Nudists believe that human bodies are beautiful. Make this your mindset, too. This should be an enjoyable experience. After all, it is a day at that beach or a vacation. Try to treat it like you would treat any other sun filled excursion. Take your usual beach materials, such as an engaging book or some music. Don't be hard on yourself. If you feel uncomfortable at first, give yourself some time to start enjoying the experience.
Familiarize yourself with the guidelines. Be confident. Stay open-minded. Have fun.
