You'll probably want to make sure to not bring expensive jewelry or excessive amounts of money that could easily be lost It may also depend on what country you are, brothels are legal in some places and not in others, so legal ones probably have strict rules and such. Less legal ones may not, but you also have to worry about what else can happen.

I haven't been to one. That being said, the most important thing I'd recommend you do is use protection! Yes condoms can be a drag but you don't know how many other people have slept with the girl you're going to be sleeping with. Better safe than sorry! If it's above board, then yes, they most likely have mandatory std testing etc for the employees, like they do in the adult film industry but I wouldn't trust that 100 percent.

Also, I'd make sure to not bring in valuables or cash on my person just to be on the safe side.
