With my very first T, I had a series of conversations about touch (I wrote about one of them in this post if you want to read it). It worked out so that we only hugged when she offered, which wasn't ideal because there were times when I would have liked a hug but I didn't think she'd give me one if I asked but was better than nothing because at least sometimes she hugged me. (She was very kind and I don't believe she was intentionally being mean or withholding--it was complicated.)

None of my subsequent Ts have deigned to touch me, except when T3 hugged me to say goodbye. (She offered, which surprised me because she'd been so against touch the whole time we'd worked together, but I accepted.)
