Why do I feel disconnected from my body when I have sex

When I have sex I no longer enjoy it, I feel extremely disconnected from my body and I don’t even enjoy it anymore. I have been sexually assaulted in the past but I’m not sure if that’s the reason why. I just can’t bring myself to even want to have sex anymore. The thought doesn’t tempt me whatsoever. And I used to be an extremely sexual being and I enjoyed sex a lot but now it’s like I have no feeling when I think about it or do it. I don’t even like masturbating anymore either and everything sexual completely turns me off. I feel numb honestly 😐
