first kiss tips?

I'm 13 and my boyfriend said he was going to kiss me if I let him and I want him to kiss me because I haven't had my first kiss yet. I'm kinda nervous😬 it will be his first kiss too. But like I don't know when he will kiss me but I don't wan it to be awkward or anything like that. And I don't want the kiss to be bad. And also I have a question. We won't be making out or anything I don't think but like when you kiss someone, do your teeth get in the way? Just wondering😂okayy that's all. Any advice or how was your first kiss and how was it good or bad?
I think he might kiss me tomorrow if we have school. We might get out because of the snow. He told me to me him by the restroom at 10:30 idk if he's gonna kiss me but I hope so😊
