What's the point of kissing someone on first or second date?

What's the point of kissing someone on first or second date? I don't understand what people want to get out of when they kiss someone that they barely know and are not in a relationship with.

Is that a way to determine if there's a deal breaker, for example, if the other person's kissing style/skill is not the way the person wants?

(Regardless, people can work on the way they kiss. Skills & styles are developed. If people can work on accents that they've grown up with, kissing isn't as difficult to work on, as long as it's something that a person thinks needs worked on and is interested in working on it.)

Because after kissing on first and/or second dates, people go on being strangers anyway. It's not like they get into relationships with those that they kiss, so what's the point? 🤔

If I were to initiate a kiss with a guy, I would probably be interested in more than just one kiss, or just kisses, and I don't sleep with a guy unless I'm in a relationship with him, that's why I want to know other people's opinions and perspectives on kissing on first/second date.

For those who think that kissing on first or second date is good way of seeing if there's chemistry, how do you think people can spark chemistry with strangers? Since it might not occur on first date and can be built with time. Thank you.

I just went on second date with a guy. After we hugged at the end of the date, he asked me "No kiss?" We kissed. I haven't heard from him again. Situation like this. Why asked me for a kiss if he didn't plan on seeing me again? He had wanted to kiss me, and just wanted to make sure he did that before never seeing me again?
