I get this totally, but unfortunately in today's climate an ethical T simply wouldn't and couldn't take the risk of touching you without permission. They have to know you're okay with it first, or else risk being sued (more likely in the US) or retraumatising you, or both.

Sometimes when a T knows you very well, like if you've been working together for a while, and T knows you're fine with touch, they may instigate it on their own, but ONLY if it's a dead cert that you're fine with it, and even then it's a very iffy area. My T knows I love hugs and we hug at the end, so now she automatically holds out her arms. But she knows and I know that I could refuse (not that I ever would, she gives great hugs!). One of my past Ts also held out her arms to me, but only after I complained sulkily that it was always up to me and she never instigated it.

So I get you - but ethics have to come first. Never trust a T who goes to touch you without permission. It does sound like you want to reject the T before you can be rejected? Or am I misreading your post? That would definitely be something to bring up in therapy, but not acted out hopefully.
