As a college ball player and a good looking guy I've never heard a problem with women and am able to pull any girl so take my advice. I don't ever use pick up lines cuz they are corny and it's obvious you are trying to impress them.

Instead do this:

Girls love attention right? Well, don't give it to them. Try to kind of ignore them and don't pay too much attention to them. Still talk to them and be polite but make it seem like your aren't too interested. This works everytime because now they will try to get you since they've lost their confidence. This works the best with hotter girls because they expect guys to be all over them. So this way they'll come to you instead of you coming to them.

Now the next step is once you are alone to completely open up and charm them to the moon and back. Now this is completely up to you which way you want to do this, you can do this simply by just being yourself(I highly recommend it) or pull it Wedding Crashers style, I don't give a shit, it should work.

I've been pulling that move for years now and haven't failed yet. And probably won't since I have a girl of my dreams now so I won't be trying anymore.

Good luck!
