I recently had a wonderful reaction from my therapist when I told him that I was dealing with some erotic transferance with him. He said it was okay, it happens, not to feel bad about it. He said we should dig into it to see what it is I'm missing, looking for.
Honestly, I don't think it could have been handled better. I didn't feel shamed by him, he helped alleviate the shame I was feeling. He still gave me a hug at the end of our session.
I told my one-on-one therapist about my conversation with my group therapist (the erotic transference) and he was really laid back and easy to talk about it too.
