Yeah worm, read Gunwitch he went into it deeper.
It's very simple, you know how you get horny around a chick?
Okay, take your horniness, and channel it through your eyes, the way you walk, the way you talk, how you touch her, and in your conversation.
It's a non verbal "I'm bout to fvck the shyt outta you." It's not the sloppy verbal shouting, "I wanna fvck the shyt outta you!"
See what I mean? And even outside of college, it's the same. This never changes.
Get this down pat, and keep it. It will be with you for the rest of your life, and you might have 90 other problems, but a chick won't be one of them.
