Hey Dark Knight,
First off, don't get ahead of yourself. Remember that creating attraction is a process! You don't just meet a girl then hop right into attraction. You might be getting ahead of yourself and become frustrated because of it.
So you're in college, which is good because you can't help but meet women in college, as you pretty much point out in your post. But when you do meet them, it's important to do two things first and foremost:
1. Create rapport
2. Build Comfort
Once you do these two things, then you can start on the attraction/flirting phase of things. Now, sometimes you can do both of these quickly, sometimes they take time. But if you look at it as a process where you go from step one, step two, step three, etc., you'll take a lot of pressure off yourself to perform.
Also remember that if you mess up, it's okay! You're going to have a lot of opportunity to practice. Just keep at it until you get good. It's just like anything else in life - the more you do it, the better you get at it. :-)
