How do you talk to men?

How do you flirt with men? I have met incredible men but I get so shy and I don't know how to flirt.

I was introduced to this guy and I couldn't talk to him I was blushing and shy and he was the one interested in me and well I thought he was attractive but I couldn't bring myself to talk to him and he didn't leave his number or anything I said that I was leaving it was a social event fundraiser and he said if you are leaving I'm going to go also and I thought maybe he would invite me on a date and we both looked like we wanted to say something then left and I've thought about him

I'd like to know how do you approach men that you are interested in or they are interested in you and successful go on a date or have a man ask you out
