The problem with touch in therapy is not just danger but that its one way touch. They are not touching you out of mutual need. Tho I am not saying a T cant enjoy a hug but they arent hugging you because they need it. They dont need you to meet any touch needs like the client may have.

One way touch can feel lonely and cause more distress. Maybe your t realises this. Real feelings are involved here and he may not want to send you mixed signals that he wants or needs your touch.
