This category was created a few years ago by LFP to replace the "Massage" section when it was deemed no longer appropriate considering that no RMTs were advertising there. These days, it's a mix of private massages, some SP services, and once in a while you'll find one who will actually do a private lap dance followed by some extras. The reviews here should give you some clues about who's doing what. Better yet, call the ads, visit one, and write a review yourself.
