Platonic touch can be very comforting, and it can bring people closer. The over-sexualization of touch is unfortunate.

DP--it's clear that your T--rightly or wrongly--thinks you have romantic feelings for him, and that's probably why he's disallowing more touch. It makes sense for a therapist to not want to encourage (or do anything the could be interpreted as encouraging) those feelings, and it doesn't mean he thinks you're disgusting or anything like that.
