It's hard to know where the discomfort comes from—fear of romantic transference or concern that it's not helpful therapeutically to focus on the therapist. There is zero chance of anything related to the former in my case, however my therapist is pretty hardlined about not being any kind of focus of my therapy. I may be wrong, but my experience bears out that most therapists don't do psychodynamic or attachment based therapy. Maybe some can handle it if it comes up, but I think most just want to deal with how the person is handling life outside the therapy relationship.
