Glad the date went well, Chihiro (aside from the kissing). And good he took it well when you didn't want to go further.

Sorry about the kissing--I've dated a few like that (or other variations of bad kissing). With kissing (or anything like that), I think it can be better to tell him what you *do* like vs. what you don't. Like, "I like kissing with mouths more closed" or "I like it when you do x." Though one of the first guys I kissed said something like "Relax your lips more" (probably the opposite of what you'd want to tell the geneticist!) and after a moment of thinking "Oh no, I'm a bad kisser," I was actually grateful he gave me feedback. Maybe something like, "I really like kissing you, but I tend to like kisses that are more ____." Maybe demonstrate? OK, I'll stop now!
