This is actually something I want too, just once, but I'd never ask for it. I had some previous therapists (Psychologists) who used appropriate touch in session (resting their hand over mine, or placing a hand on my shoulder when I was talking about difficult stuff for example, and giving encouraging hugs when they could tell it would be of benefit to me). Then I saw a Pdoc who abused me (psychologically as well as through sexualisation of therapy) and since then I've felt like ANY form of touch in therapy is like a 'Hell no, I wont go' type area. It's starting to feel like the last hold over of my getting past what that other prick did to me, and I really want to ask my Pdoc, "Please can I hug you, just once, just to help wash away that part of my prior experience". I never would though, because he's totally not the hand holding/patient hugging type. That doesn't mean he's not empathic or he doesn't care, he just shows it in other ways, and I'd never want to ask him for anything that would make him feel uncomfortable or obliged.

tl;dr I kind of understand you wanting that sort of healing touch in your sessions, but I think it depends on whether you can accept your T as they are and accept that perhaps for them showing that they are able to be empathetic and care about you won't necessarily mean they get (appropriately) 'hands on'.
