I don't know why it's such a big deal to at LEAST make off with a number with EVERY girl that you meet that you find interesting. I meet girls all the time, but I usually only go for a phone number with a girl I find really interesting, if she hasn't already asked me for mine.
Sure, I could get a black book, and spend a month filling it with countless phone numbers, but that doesn't make me any more (or even less) successful than someone who manages to ONS with every chick they meet.
Everybody gives good advice... well, not EVERYBODY, but most do... the problem is, nobody explains who this advice applies to. What I mean by that is, for example, myself. I'm not looking to bang 2000 women before the end of this year. I'm looking for a cute girl with an awesome personality. So I go out and meet lots of chicks, becuse the more girls I meet, the more chances I have of finding a suitable one. Therefore, getting ****loads of phone numbers is pointless. This information wouldn't apply too much to me, because half the time, I've already made up my decision about them after approaching them and having a small conversation.
Now, as for making the ho say no, I agree with this, if you're just looking for a hookup. However, and I think this has been cleared up, but I still want to add my two cents. There is a fine line between a girl "saying" no, and a girl "screaming" no, metaphorically speaking. If a girl has to spell out the word NO, then you've gone too far, and missed all the body language cue's that would normally tell a dude, "Hey, back off brother, before you really screw things up and embarass me." Sometimes, it may even be just a test. I've had girls tell me no, just to see how I reacted. The thing was, even though they -said- no, their body's were saying "yes yes yes yes yes!". It's up to you to figure out what's really going on, based a little on what they say, and a lot on what they do... which has been covered 15-hundred million times on this board, so I guess one more won't hurt, huh?
