I prefer not to know and see what happens and how the session develops. As long as members of this forum say they had a good experience, I’m good. As always YMMV. So your experience might not be the same as others.
Yes some masseurs don’t like give specific details about the session via text. I never ask. Rentmasseur helps a little by having 3 options therapeutic, sensual and erotic but that’s just a general idea of what the masseur is willing to do.
