You can normally feel it when someone wants you to kiss them.
But things to pay attention to is
If during the date she looks at you a lot, like she can't take her eyes off you.
She touches you a lot. (Your hand/arm. Walks every close to you, to were y'all brush up against each other. If she's touching your leg in a flirty way or anything similar, she wants more than a kiss or is thinking about more than a kiss at least. lol)
The things you talk about during the date. How personal does she get with you.
Have you ever felt the mutual attraction? A "moment". That's when you know a kiss would be good. Start out as a sweet kiss and judge by her reaction if she wants the kiss to be deeper. First kiss there isn't a rule for most women. First, Second, Third, it doesn't really matter, it depends on chemistry. Sometimes it takes a few dates to really feel it and sometimes it's right way.
You could go in 90% it won't hurt. If she wants to kiss you she will.
Normally after a date the guy would look at my lips and up to my eyes, almost like asking for permission to kiss me. It was very obvious. I'd step closer into him and he'd go the rest of the way.

Lean in 90% of the way and hold. Let the tension build for a moment. Then one of three things will happen:
1) She'll object and then you STOP
2) She'll go the last 10% and kiss you
3) She won't do anything in which case you then proceed to kiss her.
You're making your intentions known, but she has the opportunity to object and you're not "Asking permission" like a male feminist cuck which only ruins the mood.
Also some women just don't kiss on the first date, so don't take it personally.
