I am a female and my T is a male. I'm not really a hugger and didn't even think that was a option in therapy at first but I got my first hug when I was going away for almost 2 months and that was after year and a half in therapy. Since then I got few more, after a tough session, or when I'm particularly sad, he would ask me if he can give me a hug before I leave. I have to say they are very comforting. No frame, just normal people hug. I think it's ok as long as both people feel safe. And I would definitely not want them every session.
Oh, and I never thought I would do that, but last time I actually asked for one myself!
