I understand where your fear is coming from. But remember, your T knows how to take care of himself. He is a healthy, well adjusted adult I assume. Not wanting to have sex with your therapist does not make you odd (though Freud would probably disagree). I think you are taking your fear of how you believe he should take the news and projecting it on to him - believing because YOU would take it as rejection HE will take it as rejection. I am sure you have not alienated yourself from him at all. Erotic transference can work for some people, and not for others. Just because you do not feel it does not mean there is any less of emotionally connected relationship. It means, you know the boundaries and are comfortable with them in this relationship. He realizes this is a GOOD thing!
