I dunno, but I believe that girls should never make the first move. My biology teacher once said to us, "Sperms are the ones who go looking for the egg cell. That's why women should never go after a man."
It's like, it's their duty to do the actual courting and stuff. If he's to stupid to make the first move, then I guess the most that we can do is to give him an opening. But still, to me that's kind of un-womanly. If he's too "shy" to make the first move, then you don't deserve him.
