I really don't think there's a one-size-fits-all answer. I had some erotic transference with my last T. I had to terminate early due to clinic restructuring. He gave me a hug at the end of our last session. He asked me if he could give me a hug. It didn't cause me any damage.

I know this because I'm allowed to contact him any time I wish, which has amounted to probably 3 emails in the past 2 years.

It just really depends upon what the client is able to handle.
