Please read cause im worried

Okay so this is about my first bf, knew me from school and he had started texting me and kept texting me for over 4 months ... he was always so sweet but then shortly after... he asked for nudes and i said never, and then he begged and begged over and over everynight and finally i gave in and said only if you promise never to show another soul no matter what. So he promised and i took one. I never asked him for any ever. Soon after that, it became a everyday thing and i was really gullible so i let it happen. i broke up with him finally because advise i had gotten from my best guy friend, and i realized he just used me for sex and pics. Anyways the reason im worried is cause i ffear anyone ever seeing them. My face isnt in any of them so should i be okay? And i dont think i ever showed anything fully... usually had some type of something covering up my bits , so should i worry? We are both 17 and idk if any laws could get him if he ever did post or show them... but what do you all think, should i worry my self ??? Also im pretty sure he would never be stupid enough to ever do that cause he really did care about me and idk he has had multiple gfs and they definitely have sent him nudes and none of them ever got out , i only know this cause my guy bestfriend used to be friends with him, and he would literally do anything for me and make sure if he ever did hed pay. So
