I have thought about what it is about and why even do it? In my point of view it is all about making the girl/woman feel attracted so he has a biological and psychological desire for you. If you can not do that, it is impossible for a woman to sleep with you or even date you.

You have to convince her by having goal in life, being social, no needing anyone and not get overwhelmed by her beauty and having a stoic personality that your emotions do not control you.
