Oh, thanks for the reply! How much do they usually cost? like $200 or so? I'm really nervous to even call them :/
Prostitution used to be a common way of introducing young men to sex, largely because before 1920 or so most big cities in the U.S. allowed regulated and safe prostitution.
I would suggest that you take some of the guidance above, but make it a project to study: Is there an alternative newspaper where you live? It will have ads. Check the internet resources mentioned above. Take a month or so; see what ads stay up, and which vanish. There are other resources. Try USA Sex Guide (new) for some local comments.
Take your time. Life is good.
