Ooooo, yes, that pulling-and-slightly-stinging sensation when someone comes up and rubs my back. It's unpleasant enough for me that I move my body away. I can only surmise that this is pleasant for the other person, because people keep doing it. I have started to develop a habit of getting my hair out of the way when someone I don't know extends a hand. The guy (yes, always a guy) usually looks at me funny, but there's a bonus: that's often when he clues in that what *I* want might not be what *he* wants.
