I've gotten an erection while being massaged by a guy therapist a few times, and it had NOTHING to do with him or sex. I liken it to morning wood, just so relaxed, hormones moving... Draping was used in both cases, towel, and was in a sports massage legit situation. Both I and the therapist knew I was hard even with the towel. The first time I got hard on a table I sat up, apoligized to the guy, said, i don't know wtf is going on down there, but im sorry about that. He laughed, said, "lay down and relax, it's completely normal, non-sexual," and that he's as uninterested in that as i am in him. He really put me at ease, happened one other time, out of the blue. i ignored it, so did the male therapist. I'm much more UNCOMFORTABLE with a female therapist as i think they are more likely to view this as sexual or something of a come on. My experience has been that male therapists seem to understand, our sticks have minds of their own, and think with their own heads sometimes.
