🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️ idk what to do

So this guy and I were on the couch he was texting his friend on Snapchat he showed it to me which was fine. I was giving him a bj but then I notice his flashed turned on and I looked up and he was recording me! He never ask for my permission . I stormed out upset because I never had someone recording me on the plus side I’m paranoid that it will go out. I left and my dumb self forgot to ask for his for so I can delete it. Should I black mail him and say if he won’t delete it I’ll tell the cops?
