How do I flirt better?

no man you dont ask how many guys she has been with unless your goin on a date with her or goin steady and that last part looked a little odd..you ask her that and leave. Next time you ask her questions like on what she likes doing and by you askin those questions to her then it will give her a small hint that you are interested but your not comin off to strong and then ask her out somewhere if shes giving you signs that she likes you back.
