You guys ask someone there number after talking with a 14 year old for a half hour? I talk to so many people and don't ask there numbers that quick >_>
There's a fundamental difference between talking to someone as a friend and talking to someone with the intention of dating and possibly sexing them. Not understanding this difference is the reason so many people get stuck in the hellish friend zone with nothing but their right hand to keep them company.
Besides, it's just a phone number, the worst thing that could likely happen to you when asking for one is if she says no. And in that case It's an obvious and clear sign (something rare and welcome in the world of dating) that she is uninterested and not worth making a big deal over.
You're not going to get anywhere if you romanticize relationships so much that you consider them some sort of sacred, unattainable, ultimate status symbol.
