There are, in essence, two main classes of women you can hook up with.
The first class is the women who just want you. These women find you attractive (some, even irresistible), compelling, magnetic. There's something about you they like -- or there might be many things about you they like. They're fascinated by you the moment you walk up, or they've grown attached to you over time as they've gotten to know you. They like you, and they actively want to date you, spend time with you, connect with you, be in physical contact with you.
The second class is women who aren't particularly desirous of you, but they are available to you. Many of these women are just bored. Some of them may be available because they're out to rebel, and you fit the "If I hook up with this guy, I'll really be rebelling against Mom/society/my overbearing boyfriend" idea they have in their heads. Some may be available to you for revenge. For some it might be because they want to have an experience. In each of these cases, these women don't want you or like you so much as they want some guy... and you happen to be the best guy available who makes it easy for such a girl to satisfy her mission.
We've talked about this before on Girls Chase. But I really want to dive deep in this article on the girls in the second class.
Because a lot of guys don't even recognize how many women are out there like this at any given time. The fact is though, if you're good with girls, a lot of the women you get will likely come from this class.
