You know, everyone who starts to flirt with women in the begining with the first sight of interest they are sure that the woman is attracted to them. She's not, most of the times she's not. When you see that she's interested in you at the first 2-3 minutes it's not cause she is attracted to you but cause she starts to feel comfortable with you, as a person, not as a man/male(yet). At that point you have just to keep the conversation go, for the next 4-6 minutes ask questions, tell her things about yourself and get to know her a little better. Try to touch her at some point, not as a creep but as it's you, a person that can communicate with you body language and your hands. If you see her react like normal and accepts it, you can start the attraction game and get things a little more sexual every next minute. The way to make her attracted to you is not a simple, but not a hard thing to do. One way is the fake reject her, or make a compliment and then take it back like "What a nice bracelet, from where street did you find it from?" or "You're sagittarius?? Omg, we're breaking up, I can't stand this". All these with a sense of humor, don't laugh but let her know that you're not serious about that.

All this is for the first approach with a woman, but it's also a guide to maintain a good contact with every woman as long as you see each other. That's all from my personal experience, thanks for reading and you find it useful, feel free to comment!!
