Hm.
Well.
I'm a girl.

BOO!
But perhaps you could try focusing on their face? You don't have to look them in the eye, but perhaps their mouth or a lock of hair or something when talking. There's so much of a girl, her chest area isn't the only part to focus on.
I used to have a hard time talking to guys. But I kind of pretended I'd be talking to my (imaginary) brother or cousin, and that helped to make it a lot easier for me to talk to a guy:) 'Cause when you're siblings, you don't have to constantly think about making the right impression and saying/doing the right thing etc. And you can be honest.
You talk to girls like you would with guys (or perhaps your mum;)) but perhaps a bit gentler, depending on what you're personality is like. And you just act like you always act.
Try not to make a big deal out of it, they're not as mysterious as you might think:)
Common things are usually the best way to start a conversation and to keep it going.. e.g. a new movie at the theater, a certain restaurant, Summer vacation plans etc.
Yea theres a point, i happen to go for girls that have really nice smiles for some reason
Think what my problem is when i actually grow some balls and talk to a girl, i get paranoid that i'm boring them
