Yikes. I am seeing red flags here.
1. You have kissed more different people than he has, but he's confidently criticizing *your* kissing style.
2. He wants to "train" you??? puh-leez! I would find that highly offensive. If he was joking when he said it, it's still borderline offensive - not a good thing to say. I'm not saying people shouldn't ever make that kind of joke, but for it to not be offensive, there needs to be good trust and intimacy between the two people.
3. The description you've given of his kissing style makes it sound like he's the "bad kisser". Sounds like a parent bird darting in to feed a baby bird.
I probably should have asked in the first place - do you live in a country other than the US, Canada, or Western Europe? If you do, there may be some cultural aspect of your situation that I don't understand. As far as his point of view goes, I mean. You sound perfectly clear and like you know what you want.
This story made me think about a guy I went out with a few times when I was in college. He was a couple of years older than me, and our kissing styles were totally incompatible. He complained about how I kissed. Since he was practically bruising my mouth (one of those people who let their teeth get in the way), I was pretty sure that his kissing style was the problem. I was too polite to tell him what I thought, though. I wasn't interested in a relationship with him, anyway. He was an interesting dinner companion, and I enjoyed talking to him (super smart guy.) We just sort of stopped going out after a while. I'm having flashbacks to bad kissers now...the "drooler", the "lamprey". *shudder*
