Your boundaries are your boundaries and no matter what they are valid.

My T has never touched me. I know some people share hugs, but we don't even shake hands, and I am comfortable with the relationship just the way it is. The boundaries (his and mine) make me feel safe.

(Unless, of course, I want to break them down, but that's another story altogether.)

If you are uncomfortable in any way you should tell him straight out. If he is unresponsive or defensive I would consider ending the relationship. A therapeutic relationship, by nature, is one where the T has more power and if you have any sense that something is amiss then you should trust your instincts immediately.

Good luck and take gentle care.
