The bar is in a quite little street very discreet. 2 floors with some dark rooms. I was last week on a Saturday afternoon (17h00) and it was full of guys. Some days you must be nude, others you can just be in trousers (you are free to be naked all time). There's a dark room with slangs : some 15 men were having action very rude (gang or trio style) in one room. But you can just watch, all in the dark. People are very respectful : you can do what you want and it will be a good experience.
