my t does what i would think is 'normal' touching. he'll put a hand on my shoulder (like a a gentle pat or whatever) when i'm leaving occasionally. that's about it. he's hugged me once, but it was a very unusual setting. he says he's okay with hugging so i s'pose if i wanted it i could ask for it, but i prefer not to. i'm a hugger, but the therapy relationship is so odd to me that i'd rather just come home and hug my husband
that said, if i had a hard session again, similar to that one, i might ask and i think i'll give him one whenever we eventually end. but again, i'm a hugger (but i ask before hand!).
