Being smart just isn't enough. There's a reason you're called nerdsluts. So if you're going to pursue, it helps if you actually put out. Waving your status around won't impress them. You may be used to girls falling all over you because you have a great job, or a fabulous apartment, or a great wardrobe.
Conversation is of the utmost importance.
This can't be stressed enough. If this is a strain for you, you might want to just stick to unadorned sluts. E-mail is a great flirting medium. Most nerdsluts have more than one e-mail account. It's a preferred mode of communication during daytime hours, and you should exploit it to your utmost.
