Don't do this in public? By 'this' I'm assuming u mean go nude around other people. If that's what you mean, absolutely we do. For nudists, nudity is NOT about sex. It is about enjoying life in the nude. For Christian nudists, it's about enjoying life as God created us ("And the man and his wife were both naked and were not ashamed."), that is, in His likeness and in His image, and without clothes.
