How old are you know? I'm guessing you're still a minor or there would be no point in going to the police.
The first aim of any therapy for trauma is enduring physical, emotional and psychological safety. No T should be addressing trauma directly if they have concerns for your safety, it's dangerous, poor practice.
If the BDSM and poly aspects of your relationship mirror aspects of your abuse (rape enactment, causing physical pain, humiliation, drugging, multiple partners) I can see why your T would be concerned that you might be recreating your trauma and therefore may not be psychologically safe to do trauma work. You could try to find a kink-friendly therapist but tbh I think most Ts would be concerned given the nature of your trauma.
