Help? How to start a relationship?

I'm 26F and I've never dated anyone or even been anywhere close to

I'm here to ask for tips because I don't know how to start being flirty or more like when (?).

Should I wait for some hints?

What do you do when you see a cute guy? You talk to him and see where it goes?

And then what? When is it okay (after getting to know him a little to start being flirty?)

I was never asked on a date in real life and dating apps seem so forced it gets boring

If you don't mind and have some time please give me some hints

Thank you in advance 😊
