Advertising sensual/erotic to get your attention, then stating therapeutic-only when you initially contact them. I'm not looking for an escort experience anyway, but more a good massage that slips a bit into mildly inappropriate. But if it's not even going that far, don't advertise that it goes way beyond my tame little hopes.
Have had one who gave a great massage, but got progressively chatty, more political, and more conspiratorial as he continued, while having no idea what my views were.
