Here in SF, if you get out and about at all, you will see escorts and masseurs. In particular, if you go to a popular SOMA gym, you will see LOTS of escorts and masseurs. It becomes a commonplace experience. One time, I saw my favorite porn actor of all time, Tom Vaccaro, on a treadmill. He glanced over at me, we smiled at each other and we each went back to what we were doing. Only a couple weeks ago, I was waiting in line at Kaiser to pick up a script and right behind me was a masseur I had seen a few months before. It was an exceptional massage with a nice erotic component. We said Hi, I reminded him what my name was and we chatted in line while we were waiting - no discomfort at all.
