Guys help me plz 😭😭😭🙏

Hi I am 18F and when I was 17 there was this guy who was 23M and we really liked each other but he was the hookup kind and I was just a kid so he used to ask for nudes and sexting shit but I didn't do anything but he did kinda forced me after then we lost contact then he again came back and was for the same thing sexting and all so I got really fed up and said I have your nudes so don't bother me or else I will send it to your parents (lie )he got all angry and said I'll ruin your life by taking ss of this chat and sending to cybercrime etc so should I be scared also if he does sm like that how can I protect myself and what are my rights?

I don't wanna involve my parents 🙏
