Communal spaces at an FKK club can get frisky with some guests opting not to take their hostess to a private room. They are set up like a sauna club where guests can enjoy all of the facilities, but also have pay for sex on site with a prostitute. Ostensibly, a lifestyle movement that champions naturism, the FKK movement is different to the term FKK clubs.įKK clubs are not just places where nudists can spend time together but have come to be synonymous with a sex club. FKK stands for the German word freikörperkultur which translates to Free Body Culture.
