The feeling is strange. If you walk through the portal, which is formed by two stark naked people standing opposite each other, it puts you as a visitor in a strange state. On the one hand, one is impressed by the stoic posture of the two performers, who do not move an inch, even though their bodies are brushed against by people passing by. On the other hand, you also feel uncomfortable the moment you squeeze past them. How often do you get so close to complete strangers?
