Bathhouses are not what they were years ago. In a time when there was no internet and gay bars were still rare, these were ways to meet other men.
Now, it's just a place where discreet, not-out positive guys (most) go to have anon sex. (my opinion)
As a sensitive guy, I shouldn't have gone, but my friend took me so we could have the experience:
Dark labyrinth maze with porno on. Lots of uglies, druggies, and old men. Rooms with enough space for a twin bed and you to stand up. We ran into a 19 yr old crack addict who was hiv positive. He was friendly and nice to talk to in order to avoid the 3 zombies stalking us around the maze since he had a room.
I sat down somewhere in there and picked up scabies. I did absolutely nothing sexual there (I don't think I even got an erection). I had scabies for 3 months, not knowing why I was waking up for the first 3 weeks 5 times a night to itch myself to bloody wounds.
So, there's no reason to go. If you do go, I recommend NOT sitting down or touching anything you don't need to touch. Be a Puritan in there lol.
