My first T was more of a blank slate. She also practiced psychodynamic therapy. I didn't like it. I felt like I spent more energy trying to find out about her than focusing on me.

My current T is the opposite. She tells me about her and her family if it's relevant. I know a lot about her because therapy is in her house, and I see her photos and her things in the house. I also have met her husband and children. She says I can ask her anything, though she may not answer me all of the time.

Curiously, I became attached to each of my Ts regardless of their orientation.

Moonrise, if you discover that it really bothers you a lot to have a T who is a blank slate, I'd suggest changing Ts. Her orientation isn't good or bad, but you need to be comfortable with it and with her in order for therapy to be successful.
