I have never shook my T's hand. But I did talk to her about hugs at the first session. Hugs are important to me.

If you aren't comfortable with hugs, I would discuss it with your T before he might initiate a hug. Even if you're not sure whether you'd like it or not, it's best to get it out there in the open. He might not even be okay with hugs, so you might not have to worry at all. Plus by being open, he might be able to help you with any issues you have with touch.
