IMO feelings are what they are. Trying to stop them is like trying to stop a train. They aren't good or bad, and usually there is a reason underneath them. Exploring that reason may prove to be a powerful focus of your therapy rather than a distraction from it.

I would definitely try not to be too hard on yourself about the erotic transference thing okay? You know how people get to animals to mate in captivity? They simply put them together and walk away. Now, add to that intimate feelings flying about and WHAM! you've set the stage for some pretty strong and passionate stuff. It happens. It's human nature. Try to rest easy with it. Those feelings can exist in that room and they don't have to spoil, or disrupt anything. The boundaries are there for a reason - to protect you both. Trust them and trust yourself.

You're not going to stalk this guy unless you give yourself permission to do it, and IMO the best way to end up stalking him is to push those feelings down.

Does your therapist already know? That's hard to say. It's okay even if he does don't you think?

One thing I am going to put out there right now, and this was something that ultimately resolved the "transference" for me permanently.

Your experience of therapy is dramatically different from that of your therapist. The flow of intimacy is, at its heart, one way. Your therapist is simply not going to experience you the way you experience him and that is perfectly okay. The relationship that you two establish with each other is still mutual (albeit different in perspective) and good enough.

The way you feel is wonderful and part of therapy for some. Try to relax against it and enjoy the way you feel. Accept it for what it is.

And the standard psychcentral advice - talk to your therapist about it.
