Wow, that sounds wonderful Treehouse.
I think being hugged by your T (if you're comfortable with it) can be a way of sharing a human connection with him/her. It's non-verbal and very powerful and loving in its own way.
I'm wondering, though...for those of you who do hug...are the hugs very quick or more of a comfort thing? Our hug was not a release and go type of hug...it was a longer lasting solidify the bond type of hug (if such a hug exists anyway). I'd never asked for a hug before so I don't know if he'd have given me one sooner or not. I asked for a handshake as I was leaving, but he knew I wanted a hug so he offered. For me it was a healthy thing to do.
