I can't imagine hugging my T. Our relationship seems too business like for that. I mean, I know I tell her very intimate stuff but... listening to that is her job. I need her job to be focused on helping me sort out me. But it is her job and the relationship is a professional one. I wouldn't hug her and it would freak me the heck out if she wanted to hug me.
I did hug my ex T when we terminated. I wouldn't have asked to, but she asked me how i wanted to say goodbye... with a hug, words or a handshake. A little one of me wanted the hug. But I don't think I could stomach it at any other time.
