My T is psychanalytically trained and also a psychiatrist. So she welcomes both negative and positive transference. When talked about it improves our relationship. Maybe not for me in the moment, but I end up understanding my behavior. She actually told me once that if I developed any erotic transference that it was ok to talk about it with her. She is the best T I've ever had. Because I don't have to hide anything from her.

Now, I think transference can be BAD when you have a T who hasn't had advanced training and doesn't either understand it or has their own issues.

My first T was a social worker. No advanced training after his degree. He was manipulative, used my transference and we ended up having a sexual relationship.

I suggest that before exploring your transference, you ask your T about their training. Specifically regarding transference. That way you can make sure when you disclose it you feel that your T is competant and you will be safe.
