Not on the same page for sexual intensity

So I've been dating this guy for like 2 years and he finds pain as a turn on but me not so much. I don't mind if it's just spanking but sometimes he gets really rough. He'd bite me and leave huge bruises and that doesn't turn me on at all it's just painful. He would finger me aggressively too(I'd be bleeding and swollen). It sucks that we're not on the same page But I'm not so sure on what to do. I know there's other way to please him but I feel like he'll cheat on me for someone else who likes doing all the sexual things he likes.
