Is it normal that i want to bang him

(keep in mind I'm a teen) So there waa this guy that I had a thing with, we hadnt officially been dating but had makeout sessions a fair few times going aa far as groping and rubbing places..
I then found out some things about him that I really hate and I've always been against so we stopped but now all I can think about is having sex with him which I've never seriously considered until now. Its difficult because I hate the habits he has but somehow knowing them has made him more sexually attractive?
