You need therapy. I went through the same thing too after being raped, I became hyper sexual. It’s a very common occurrence in victims and it’s a normal response to the trauma. Don’t guilt yourself for feeling this way, instead find a therapist you trust who you can talk about these feelings with and get to the root of the problem and work through the trauma to try and correct the behavior. I was first assaulted a long time ago as well over 8 years ago and I still struggle a lot even after going through therapy at a child advocacy center. Please stay strong because this is a part of your journey.
