Help no sexual chemistry!

I’ve been dating this guy for a while now. He’s 24 and I’m 19.

He’s really sweet and respectful but there’s no chemistry at all. When we kiss it’s awkward. There’s only been a few times it’s been decent. I ease into it, and he starts out with tongue. The sex is awkward he only likes missionary and he doesn’t make any noise. I’ve tried talking to him about it, like trying new positions, more eye contact, slower kissing etc. He says he doesn’t like eye contact during sex or during conversations unless it’s about something important. It’s just weird and the last time he tried to kiss me I got turned off. Should I keep trying? ..or just break it off
