Thank you very much for providing overviews of your experiences, both first and second.
I had a similar 1st vs. 2nd time experience with a masseur in San Francisco. The first time he peeled out of his clothes while I was undressing, displaying a semi-woody. We then had an extra long session (his volunteered extension) combining great therapeutic strokes and stretching with intimate sensuality. I think "Great! I have found the masseur of my dreams." The second time he showed up, didn't take off any of his clothes, and proceeded to give just an OK therapeutic massage with no sensuality. This masseur also shared a little more than I needed to know in the second session, which led me to be concerned about his mental health. I would rather he just have canceled the session if he is so depressed that he is going to make me depressed.
I know that masseurs are human too, and may approach a session in different moods, or even with different needs. But as I am essentially a purchaser of services, I look for some level of consistency in the provider.
