Yeah, the fact that it's not about sexuality occurred to me just before I logged on just now. My bad.
I still don't understand the map room having a hall that leads to itself, though.
I was able to find all the rooms but one. When I tried to follow the map to the one unlabeled room, It's just a hallway that takes you back to the map room. It has to be an analogy for something, but understanding symbolism has never been my strongsuit.
