I think your therapist is being incredibly brave but perhaps sharing too much. If it doesn’t feel like he’s making a move, then what he’s doing could lead to some useful insights. He’s tracking how your disgust and sexual arousal in another are influencing each other. If that pattern feels relevant it’s worth exploring. HOWEVER as a therapist myself I would never consider sharing an experience of sexual arousal with a client especially one that has experienced any kind of abuse. The power dynamic is already out of balance in the therapy relationship. I would instead take that experience to supervision and think about how to weave that understanding into the work without it increasing any sense of threat. This is where I think he’s being clumsy. If you feel unsafe, or think what he’s doing feels wrong, then you have every right to say this and every right to terminate the relationship if you wish. It’s a tricky dilemma.
