you are right!!!
Another clue may be when you see a massage table in the first pic.....the "masseurs" that are also in Rentmen usually do not have those pics.
In Rentmasseur they can at least uncheck the "erotic" massage box, but in Masseurfinder they took away that box some time ago.
Probably everything depends on chemistry......I have gone to get a massage with legit masseurs and we ended up having sex!!!
