You don’t just walk up to woman and ask her out.

You go to a social place, and you just start up a conversation, while she’s not talking to someone else, or obviously already socially engaged.

You find a relevant topic to start, from the moment.

“Hey, I like your hair.”

Or, “I noticed you grooving to this song, I like it too.”

Or, “You like Newcastle, too? Nice.”

Then, if she smiles, or engages in more conversation, just ask her about her. But that doesn’t guarantee anything.

And… and… she may be interested, but doesn’t want to PornHub bang you that night. Outrageous, I know. She may want to get to know you better.

This is a skill, that is learned from experience. And you will fail, a lot, until you learn it. And even if you master it, you still fail sometimes.
