There are several rules and ways to introduce yourself to women and i will tell you how.
Step 1: Tease.
Remember the key is to be open. You need to hit on every girl you see that is cute or a potential girlfriend. If you fail you get the personal experience.
First of all you need to find a girl and attract her which is shown step by step here.
The best way to come up to a girl is to ask a question or as for an opinion not just say "hi". The reason for this is because if you just say hi the conversation goes no where, but if you say something like, "Me and my friend had a little argument earlier about whether girls lie more than guys and "I know its obviously girls"(this is the kind of teasing that will get the girls attention) but i wanted your thought." Then escalate from there and stay on your toes if the conversation goes dry and after maybe a minute or two say, "Could i have you email?" if she says yes then 1 point for you if she says no say, "Oh my good friend has this band i think you would like his music so i was going to send some of his stuff to you." If she says no at first if she ends up giving you her email, do not contact her and make up a fake friend. Abandon all hope, with that girl, there are many more...just look around you.
Step 2: Make the Date.
Now you have a beautiful girls email, or maybe many. Email them and get there myspace or aim so you can have a more instant conversation. You can talk to her and make dates which can be done by simply emailing her, "Want to go for lunch on Sunday". If she says yes then begin to make details like where to eat and make sure you decide none of this "where would you" like crap. Don't make it huge, have lunch at the local diner or even a burger joint.
Step 3: 4-12 Hours.
The 4-12 hour rule states that you must touch lip to lip with this girl within 4-12 hours of hanging which means if you chat with her on aim for 1 hour that is one our, if you go to lunch for 3 hours you are at 4. If you don't kiss her within this time frame you are in the friend zone and its for pretty much forever.
Step 4: Kiss.
I can't stress enough that you need to be confident, even a tad cocky. There are many ways you can obtain a kiss. One is that you ask her for it but like this, "Did you want to kiss me?" and if she says no say, "Oh you were acting like you wanted me to." and drop it. But if she says yes lean in and make it a 3-4 second kiss, no tongue, just a tad long peck.
You can also put your pointer finger and point on your cheek to gesture for a kiss cheek which many girls don't mind giving. When she leans in turn your head and kiss her. This is much more cocky and if executed right the better choice.
Just like Hitch i leave you to work from here. Happy Dating.
