No, I don't believe this is normal at all. It sounds like it is re-traumatizing you. My therapist doesn't ask me to tell her any details about it, and has said if and when we talk about the traumas we will go at a pace that is comfortable and bearable for me and i will always be in control of it. I don't think what your therapist is doing is normal or helpful AT ALL and it seems like it would be obvious to him that it is making you uncomfortable and you don't like it.
