Hi the name's alex nice to metchaa, I have a good body build and some may wonder why I'm here. I consider myself fairly attractive body and face,even though I have a like two little pimples on my face. But heck I even wonder why I don't have game if I have a body like a football player. I'm berally 18 so its not big sweat,but I have never had a girlfriend even though I've gone out with a girl or two both of them being older than me, I don't know why. I flirt many girls many but I NEVER REALLY GET PAST THAT! What I have learned with the pua material from alex coulson, and david de angelo is that don't show you are that nice. I've never asked anyone out till yesterday and this is the reason i'm here to show my concern.
My main concern is is this site for me.
the question is
If you are not supposed to show interest then how the heck are you going to get her phone number or ask her out, all of those being interest signals. Sure you can tease her show that you are not interested but for how long?

Another question is why do girls flirt with me and show interest genuine interest. I've read a book on body language. So I know when they are gesturing like playing with their hair for up to 6 seconds or more, pupils, tilted head. I get their number, and then what'? I ask them out through a text saying he it was nice to meetcha wanna join me for a cup of coffee. I don't get a text back or they become uninterested or seem to. Am I doing something wrong here?

Thanks
Let me know if i posted this in the right spot.
