Also, that whole " Not being able to interact with girls like they do" is crap. Theres no magic skill to it, its natural.
You just gotta loosen up, and be yourself. And if you ever want to get some poon tang, then you need to get up and try again even when you get shot down over and over. Of course i dont know you at all, but seems to me like you spend too much time worrying about what the girl will think about you etc. When you should just be going with the flow.
