So?

I mean if I went through the effort of thinking out a date, and simply noticing him, I think I have the right to be a little bit selfish.

same goes for guys

Well bud, let's think about it this way.
Role play.

Let's say you're s beautiful girl...THIS beautiful girl to be exact:
God...


Okay..Now, as this girl, try to imagine how many times a guy tries to hit on you, or talk to you, or stare at you a day.
-----------------------
Now, at first, you're happy with all the attention. You speak to everyone, you have lots of friends, etc..You date a few of the guys, and you're popular. However, you're still CONSTANTLY getting hit on, or some guy wants to come talk to you, or some dude is staring at you. Imagine how frustrating this can get over time, to have conversations with someone that lead nowhere:
"Hi, umm..you're so pretty and I just wanted to come say hello. What's your name?"
"Thanks, I'm Layla, and you?"
"hi, I'm Mark. So what classes do you have/what are you here for/do you have a boyfriend? ETC ETC ETC"

Now imagine this happening EVERY DAY. Then we get the steady stream of guys openly hitting on you:
"Wow you're fucking hot kid, what's your name?"
"Hey baby, walk for me. You so fine."
"Hey, you're so pretty, want to go out some time? Here's a mixtape I made for you."
etc..etc..

Then you get the creepy stares, constantly. All day, or in particular classes, or when you go out.
------------------------------------

Now, women really can't deal with all of this shit. Their subconscious won't allow them to go through the same boring routines with each guy that wants to talk to them. They won't let themselves be emotionally or physically hurt by each asshole/nice guy that wants it in their pants. They can't handle the paranoia of the constant stares from other guys (most chicks can though)
So what do they do? They build resistance against them. It's a defense built to keep away guy that follow these routines and patterns, and are basically how a girl weeds out the man she wants.

You walk up and say,
"Hey, you're so pretty I just had to come and ask your name."
"Fuck off please." - What do you say then..she's a bitch huh? This is what I do.
"Listen, I just wanted to come over for a second and introduce myself. You seem like an interesting person who I just couldn't get by without knowing."
"Fuck off please."
"Oh that's so cute, look at you! Trying to be such a hardass, that's sweet. Here,you should flip me off too so I get the full effect. If I wasn't gay that would hurt, but i feel you girlfriend. These guys always trying to come up and get your number, I am there honey."
She laughs, I'm in.

It would take awhile to descrbe all the nuances here, but that's the main gist. Few women are truely bitches, they just don't want to deal with the same bullshit over and over. They have to protect themselves. You just have to learn how to break through that.
