I am asking this question without judgement, and from a place of genuine curiosity. Do you guys not verbalize to the provider in the moment on what you want, and/or redirect them if they are doing something unpleasant? I had a massage with someone who kept checking a beeping phone. I politely said "you know, I am finding that very disruptive. If there's some need for you to have attention elsewhere I am happy to come back another time." He apologized, silenced his phone and gave me a great rest of the session. I understand feeling vulnerable because you're naked and face down, but you have to retain ownership of your self-interest, politely.
