IMO everything I've read so far sounds really cheesy and rehearsed. I think people put too much effort into talking to women. I'm no expert, but I tend to just let things flow. If it doesn't I move on, if it does, then I'll continue to transition and transition until she's putty.
My conversations with women no matter what situation are always about the "Now". What I mean by that is, I talk about things that are happening around us at that very moment in time. I'll usually make a joke out of it. Her guard is gonna be up because she's a woman that gets approached a million times a day. Laughter will usually bring it down, but you can't just keep her laughing the entire time. You have to transition back and forth.
I'm not gonna give you the words to say. Make them up as you go. A good way to practice would be to just talk to any one, guy or girl. Go to your local VFW or something or a seniors home. Old people love to talk and they're funny as hell. Pay attention to how they transition from one point to another. Their conversation flows and at times it will seem like a story, but they're just talking.
That's the goal you should have in mind when talking to women. It sounds crazy as hell. It's just an idea though. If you feel that you're at an end, it might be worth giving a shot.
