What a woman evaluates, even before you think about approaching her, is at first: height, hair, eye color, muscle mass, beauty of the face, chin, jaw and volume underneath the pants. Second step, she observes details that give clues to your financial situation such as, an expensive watch, your phone and your car (she will try to find clues of your financial position even in times of dialogue: she wants to know if you know many places, exotic food, etc.)
Then she compares you with other possible male competitors that surround her, to know if you're among the best, among the average or among the worst. In less than three seconds, she has evaluated all these factors into you, now she’s done with this diagnosis.
If you passed the first test, she will let her guard down and be easy for you, and will let you get close and talk a little about you. What she wants is to look at other factors, to whether you are a sucker, or if you're for months without sex. It comes down to feel whether or not the guy has other women at his disposal. They have a special scent to detect men who are there some time without having sex, and run away from these thirsty seedy men!
If the guy passed these tests, she simply will pretend she was enchanted by his talk and will let you make advances! No mystery!
And if the failed in preliminary testing? Can he not reverse the situation in approach??
If she felt bad and you realize that you are a loser that has no pot to piss on or a beta that is lacking for years without f***ing a p***y, her brain has created a lock on you, and she will be angry with anything you say! She herself will do everything to make you feel embarrassed, she will make jokes after jokes about you, will humiliate you and will leave you dropped without much explanation. She will do anything for you to feel bad for approaching her!
Some may even try to argue: yeah, but the story and that some women are harder than others?
Bullshit! There’s No hard woman out there! What exists is a woman who did not like you, and she will do everything to make your life difficult! If she liked you, she herself will skip some stages of the conquest just to give it to you fast!
Others argue still: and if I insist, have patience an hour she will not notice me? I know guys that would both insist they gave!
If she did not approve of you in the first three seconds she saw you, there is still the possibility that she does not dismiss you completely. You may not be an ideal male to f**k; but who knows? you may serve as spare male, in case that thing with the guy in college, or ther new boss at work doesn't work out.
Another possibility is to put you in the friendship zone, so she has a male to do favors for her (e.g. dinners, gifts, attention, etc) without receiving anything in return. I will not be speaking here of friendzone, because this subject is already very known.
I remind you that sex will only be in case of emergencies, if she can not hook a superior male! Learn that she is only with you because she could not get anything better, and deep down she has a grudge against you because of it.
