Some ppl (me included) find it comforting when there's no touch policy. So maybe she thought you would too? Like don't worry it's safe here, I won't touch you?
However, if you crave safe touching you need to address it with your T- explain why you need it/find helpful before. Also ask her if she really has no touch policy- my T touches some clients (shakes hands, puts an arm on their shoulders, though I don't think he hugs them) and some he doesn't- he asks in the beginning of therapy. So he does treat clients differently but it's not just because of SA.
