I need tips on the bad kisser guy that i’m dating with

I really like this guy and yesterday was our first date where he kissed me and let’s just say that it’s not good at all. He was already biting and pushing his tongue inside my mouth right away and i was taken aback that i immediately pulled away after. I apologized that i wasn’t a good kisser and he comforted me but i wasn’t a bad kisser at all. In fact the last guy that i dated told me that i was a good kisser after our first kiss. I don’t know what to do. I don’t want to embarrass him because he’s quite sensitive guy. How do i make him a better kisser? He didn’t even tilted his head or opened his mouth slightly. I need your advice.
