I think that therapy is a weird relationship at times, I think that when T's maintain a rigid boundary about something like this which is very important to a client, the relationship moves into a new phase where the therapist holds a kind of destructive power, and the client can lose some of their dignity, and it can cease to be helpful. I have never wanted a T to hug me, but I have wanted a T who was blank slate to share something of herself with me, and when she wouldn't the relationship stopped being helpful. I'm in the UK too, and I know there are T's here who do hug. One T that I tried out offered me a hug after the very first session. I wonder why your T is so afraid to hug a client? Some time ago someone posted a great article for therapists about why T's shouldn't rule out giving hugs.
