You don't have to move fast to get girls. I don't know where and why Chase came up with this idea, but it does not reflect real life. In fact, it flies directly in the face of contemporary research (see:
http://thematinggrounds.com/how-to-be-a ... tic-proof/). Trust me, I spent a full year following that advice and I lost more girls than I can count because I came off as thirsty, overeager or needy.
The point is to move as fast as she will allow you. That could be weeks or months, or it could be less than 10 minutes. Or anything in between. It's a matter of reading her cues. Not assuming that "because x amount of time or dates has passed, you have to sleep with her".
Having said that...
I've heard rumors (and from my brother) that highschool girls take FOREVER to put out, I'm talking weeks and weeks, sometimes months (plural)
I've seen two types of high school girls:
1. Virgin girls who take months to have sex with. Usually they equate sex with love, are very afraid and anxious about it etc. So they won't have sex with a guy until they've already been dating for a while.
2. Absolute sloots. And I don't mean this in a derogatory way. ...I just mean that they'll fuck almost everyone. I know a few girls who left high school having had sex with 25+ guys.
Strangely, I don't see too much in between the two extremes. I don't know why.
...Anyways, if you're looking to just have sex, go for that second category of girls. If you're looking for a girlfriend, go for the first.
