I think that each person gets to decide for themselves what is acceptable or unacceptable for them. It's your preference not to want any kind of contact, and it's good that you make it known. Personally, I'm okay with "professional" contact as long as it doesn't get smothering . . . which I've never experienced from any T I've ever seen, and if the T I was seeing started to smother me or go overboard for my own personal boundaries, I'd feel fine about letting him/her know that their contact has become uncomfortable or unwelcome. When I responded to the poll, I mentioned "unprofessional" contact as something I wouldn't like because it wasn't specified in your original question that you were speaking of "professional" unbidden contact only.
