i messed up..16 yo and 20 yo

This guy msged me on grindr and said he was 18 and i believed him and sent a dick pic. 2 days later he said he lied and hes actually 16 turning 17 next month. He wanted to chill at his house so about 2 hrs ago i went over there. In text i made it clear i just wanted to chill and not do anything because hes young. Weeell then we started cuddling and he grabbed my dick and we were making out then gave each other bjs. He wanted to bottom but i told him he shouldnt because it would hurt and we didnt have lube. Now that i left i feel hella disgusted, he wants to chill again this weekend and actually bottom. Fyi i was the first guy he did anything with apparently. I told him when hes 17 we can fuck around since thats the age of consent but man its really fucking tempting, his head game was crazy. Do yall think this is as disgusting as i think it is? Im afraid if i dont respond then he'll get the cops involved as payback..i know thats a stretch but im thinking of everything rn. He really enjoyed cuddling and honesty i did too but the whole minor thing is fucking with me. I got to know him when i thought he was 18 so it just feels weird af now. Whats yall thoughts?
