Help- great guy, bad at making out

I really really like the guy I'm dating. We're hot for each other and he's a good kisser. However, he's pretty bad at making out. WAY too much tongue and a lot of teeth. His mouth/lips are a lot bigger than mine so it's almost like he's eating my face. Lol I really like him and am totally hot for him. How do I get him to be better at making out? Can I say or do something to help the situation without damaging his ego?
