Yeah man, just cause you (or a girl) exchange phone numbers doesn't mean either of you are going to call that night. I've had females call me that had my number for months before their first call. I usually go through my archives of new ones when my current queue is runnin' a little low, cause I'm not trying to focus on more than about 3 or 4 at a time. You meet up with one girl, she has friends, and they have friends, and on and on, so the number can grow exponentially. I think girls are just as horny as we are, but are better at concealing it. That's why the "quiet" ones intrigue me.
