How to teach your new SO how to kiss you right?

Second date we kiss for first time. He proceeds to open his mouth as wide as he can; I felt like he was trying to swallow my face like a snake. I was turned off by this initially but I like him so I put in effort to control the kissing. Towards the end we finally got an enjoyable sync of our kisses and he sort of toned it down and seemed to enjoy my kissing because he moaned a little and later told me he isn’t used to kissing someone who is good at kissing. I need guidance on how to get him to adjust to my level of kissing without hurting his feelings.
