Welcome! I don't think it's something for you to worry about. I think T/P is supposed to set the boundaries on that stuff. That being said, it couldn't hurt to just have the conversation with them, just to know what those boundaries are. I have issues around affection and just assume that anyone would not want to give it to me, so I don't even know if my T doesn't allow it or I'm just too chicken.

I agree with what was already said. It really depends on the therapist and what their personal policy is and how they conduct therapy. Many have a no-touch policy, some allow quick hugs, some more than that. As you can see on the forums, there is a wide variety of what is okay in therapy. I'm sure if the hugging wasn't okay at the end of session that your T would have made that known (or should have).

I would keep being yourself and do what feels right for you and they can say if they don't like it. I shake hands a lot with people in formal settings and did with my P when I first met him but was aware he was completely stunned by it. I touched him!! (horrors!). Normally I give and receive hugs in therapy and am held when the pain has me sobbing like a small child, but this P as you have probably read, has never touched a patient in his entire 23 years of practicing, so we are well tangled up in the issue of to touch or not touch right now.
You just keep being how you are and do what feels okay for you and they will probably be fine with it and if not they will say. I am feeling quite churned up around this topic these days and kinda want to get us all to hug our t's, P's and C's all round the world and like what is happening in Africa nad the MIddle East, actually CREATE change by all coming together on this one!
