Freikörperkultur
Freikörperkultur (FKK) is a German movement whose name translates to Free Body Culture. It endorses a naturistic approach to sports and community living. Behind that is the joy of the experience of nature or also of being nude itself, without direct relationship to sexuality. The followers of this culture are called traditional naturists, FKK'ler, or nudists. The German nudist movement was the first worldwide and marked the start of an increased acceptance of public nudity in Germany. Today, there are only few legal restrictions on public nudity in Germany.
