All I can say is I know what you're going through. I had my first kiss when I was in my mid-20s. Much like you, I never put much focus on dating. I didn't have the confidence to date in high school or college. Things changed for the better when I lost close to 100 pounds close to 5 years ago.

Anyway, I never knew if I should tell my date it was my first kiss. I was torn between faking it until I made it or being vulnerable and sharing that information when I wasn't even sure he'd be around after the next date. Like why share my anxiety about not kissing with a near-perfect stranger if we weren't going to be dating in another week?

After stressing for several years about kissing (much longer than I should have), I just let go of that anxiety. (Because once you have your first kiss, then the next thing to stress about [if you're anything like me] is the second kiss.) Kissing will come naturally. I know that sounds odd and isn't super helpful advice, but it's just going to be awkward if you try to script it or try to plan out the progression of the kiss by "studying up" on kissing. No to kisses are the same. No two kissers are the same. Just remember that kissing is a way to show affection. It's an enjoyable way to show affection. Here's hoping this guy is understanding and patient with you; I also hope you're patient with yourself.

I suppose if you really want to "study up" on kissing that you can look up videos on YouTube—perhaps greatest kissing scenes from movies or something. But don't set the expectations for your first kiss based on those videos; you will be severely disappointed.
