I've never directly asked for a hug. I wrote in a email that was about me and her that I want a hug. But we havent talked about that part. She had never offered one. Not even after sessions where I really cried my eyes out. I'm too afraid for a rejection to ask.
I think current T might give me a hug if I would ask for one. She's about needs and stuff. Though she would probably also want to talk about the need for a hug from her. But so far I haven't felt the need for a hug from her.
