Did have one place where something similar happened, she was an independent masseuse with her own place. After a few sessions, one day on the turn over, she noticed I was a little aroused, and made a little joke that she was supposed to relax muscles, not make them stiffer. I mentioned that I hated ending a session stiffer than I started, and she said, for a little extra, she could make sure that didn't happen. $20 tip took care of all my stiffness... it was great, a good theraputic massage (was not shy to get in there on the gluts, either, I just hate going for a massage and having the masseuse avoid the largest muscle in the body like it was radioactive), and no residual stiffness. Nothing erotic, naked or anything, just a careful hand release. She was my go to masseuse for a couple years, and then got out of the business. Don't know if I was the only guy that got the "special service", but I don't think it was a thing regularly on the menu.
