I'm 22 and attend a pretty good city college that I am satisfied with and plan to stay until graduation, but I have one huge problem.

I can't get anything going with any girls at the school

I know that social circle are important in college so Freshman year I joined a Frat (I'm a junior now). It was pretty cool but because of my reclusive nature I didn't get very close to any brothers. I was in it for parties and girls but when the parties came I stumbled around like a fool. I shut down in those social situations, I just don't know what to do. I suspended myself from the frat a year ago because I didn't the time for it.

Now I go to class come home, and that's my day. My weekends are the same thing.

How can I turn get girls in these conditions
