I got my first hug after about a year and a half when I was leaving for a longer period of time. I'm not sure what his rules about this are, I have never asked.
Recently I got couple more hugs. I'm not a hugger, but I was feeling really down and actually thought to myself that I could use a hug again. I don't know if he felt I needed or if he can read minds or what. I wouldn't ask for it but I must admit that it felt good and not weird at all.
But if he did that at the beginning, I would probably totally freak out. And I don't think I would want it every session either, then I would just get used to it and it probably wouldn't be as comforting.
