In one example the therapist told me to describe fantasies of sexual relations between him and me. He said that if I was open enough about the details of the fantasies and if he was able to become sexually aroused to the point of an erection it would mean that I was getting better. He said he looked forward to this and to being aroused because it would make him feel more alive.
I'm still trying to figure out how to recover from everything that happened in therapy.
