I agree with Pepper_mint about therapy being like a lab. The fact that all these feelings have come out is a just an indication that these longings and needs were within you. The thing is to think about why they are able to come out towards the therapist (what is the therapist providing that makes this safe) and how to get these needs tended to in your real life relationships. For example, if trust is an issue, and your therapist has generated trust, what would it take to start finding/experimenting with trust in the real world?

I will say that I had intense transference towards my therapist for quite awhile. It's pretty much gone now, since I've made some changes in my life and relationships and started some new projects. My feelings towards my therapist have shifted and although I still am very fond of him, my previous obsession feels foreign to me. I used to just think about him and therapy all the time and that is not true anymore.

How did I talk to him about it? I just bit the bullet and forced myself to discuss it openly. From my reading about transference, I got the impression that therapists are completely uncomfortable with any kind of explicitly sexual talk directed towards them. So I never said anything explicit like that.

But just revealing that you have romantic feelings and longings towards them? Therapists should be able to handle this sensitively and with understanding because it happens, like, all the time. If I was a therapist, I imagine it would make me more comfortable if my patient made it clear that she/he knew that a physical/romantic relationship was not possible and that she/he was telling me just to be honest about what was going on inside. Sometimes in therapy I thought a good rule of thumb was that the more excruciating it felt to talk about something, the more important it was to talk about it.

Also, sometimes, when my transference got bad (it waxed and waned) I would ask myself, why is this happening again now? Very often there was something I was avoiding thinking about, or an emotional feeling I was avoiding. Maybe ask yourself, "If I was not thinking about my therapist, what would I be thinking about?"
