You forgot “a friend wants to know.”
Well, it’s not silly. For example, in one place I lived the “sensuous massage” place was a very short distance, threw in a sauna visit, closed at 9PM, and the girls did nice deep shiatsu massage- and were very clean (they never did actual sex, afaik).
The only “theraputic” place was at a chiro’s office, 3x the distance, half again the cost, and closed at 6PM.
So, yes, I went to the “sensuous massage” place mostly for the massage part.
