Like I think it is awkward to kiss someone at the end of the first date or second. Even if there is a lot of chemistry. All I am saying is I think it is best to just spend time together in person for more than just a few hours before you decide to start dating. Like for me personally I like to spend about two weeks getting to know someone IRL before I ask them out. It's so much less pressure because you know them a lot better.
There is a reason friends to lovers is so successful. If you can't be good friends then you can't be good lovers.
Nothing wrong with flirting a little and there being sexual chemistry but I think wait to explore that more once you actually understand them. Then talk about an actual date. Do this IRL not over text either. Meet asp because texting kills desire.
