Polls: Girl's Behavior

I know that 'Looks are Subjective' & stuff like that but it kinda irritates me when I see a girl grind on guys she otherwise wouldn't even look at if the cross each other on the road or on a college campus lol :D So I thought of posting a survey as per what I see ot observe in clubs, but you can add more options along with your views in comments.

What what you be thinking when your Guy just starts gently stroking and patting your head (in a nurturing manner) and says something like "Good girl".

We've always assumed it was men's sexy faces, toned bodies, and feminist sensibilities that we women lusted after, but it turns out we might just have the hots for their immune systems. A powerful immune system might not sound as enticing as six pack abs, but in the long run it's probably more important. So it makes a fair amount of sense that we'd have developed a radar for who's body can defend itself, and a new study has found we rely largely on testosterone levels to tell who's healthiest.

Researchers from Abertay University in the U. K. recruited 74 Latvian men in their early 20s. They gave them a Hepatitis B vaccine, which triggers the immune system to create antibodies to fight the virus, and they took blood samples right before and one month after the first dose of the vaccine was given. They measured antibody levels, as well as levels of testosterone and the stress hormone cortisol. The researchers also showed photographs of each man to 94 Latvian women, who were also in their early 20s, and had them rate the pictures on a 10-point scale of attractiveness.

After analyzing the men's immune response and hormone levels in connection with their attractiveness score, researchers concluded that high testosterone correlated with both sexy faces and a strong immune response. It's not surprising, really, that women would find the more testosterone-y faces more attractive, since that tends to come along with more masculine facial features—and who doesn't love a macho man? (Except all of the people who don't love a macho man.

Men who had the strongest immune responses were perceived as better looking than those with the weakest. This is the first study to document that a women's attraction to a man correlates with the health of his immune system. Of course, a healthy immune system is attractive in a man for any number of reasons—they produce sturdier children, they don't cough all the time, you don't have to take care of them when they're always sick.

We've been been friends for about a year and I have a class with her
Things I've noticed:
-Doesnt smile a lot but Smiles a lot around me
-when We walk, stand, sit, etc. next to each other she's usually close (like legs/shoulders touching close)
-when we work together during class that if our hands touch accidentally for whatever reason she won't pull away.
-When we lock eyes from a distance she always flashes me a big, genuine smile
-i notice her staring at me when I turn around to talk to my friends in class
-She either holds my gaze for a bit to long or she quickly glances down and smiles when our eyes meet
-She gets really giggly sometimes and laughs at almost everything I say
-When she's in a bad mood, she instantly brightens up around me
-When I pass by her friends during the day they seem oddly silent, their whole little trio will be quiet but they see me (at least it seems so)
-Sex jokes/ doesn't mind talking sexual
-little suggestive comments for ex. Once another girl asked me for something she cut in with, "I come first" and the other girl backed off
-in my personal "bubble" a lot
-Doesnt get mad if I get caught 'looking'

Sometimes she won't text back though and she can be a bit forgetful..

by the way I'm not usually this clueless with girls, just this one lol

i'm a nice guy, i'm shy and humble.

From my own school experiences this seems to be happen a lot during middle school and early high school. Any thoughts/experiences? Sorry if this is a weird question. It's something I've always wondered about for awhile. I was always afraid that a girl would hit me there and then laugh at me. I think hitting someone there should only be done in self defense.

There's this girl I like
I try to talk to her, but she ignores me
She's not in a relationship.

She only replie "thanks" when I compliment her
And that's only if she's in the mood to say it

I can tell she reads my messages because she's active on Facebook

I would leave her alone but she really showed interest at first.
Now she just ignores me
I'd like some type of closure at least...

If you're not interested in me just say it so I can move on

(you're probably thinking I spam her with messages, I don't, it's only like one compliment every 4 or 5 days, she says thanks sometimes but other times she just doesn't really care)

I am neither dominant, nor shy, so I can act differently in different situation. I like a shy girl so I wonder how I should act to attract her. Should I be dominant and confident, or gentle, soft and a bit shy like her?

I started thinking about this when I saw this picture and comments below it:

The girl is tall but very cute and athletic while the guy is pretty short. I don't mean he is a bad person, they may like each other because of their personalities, but it seems that tall girls are more open to dating short guys than average height girls because they can't get other guys and feel insecure.

Maybe this thing works for chubby girls too? I am an average height skinny guy and I rarely notice chubby or tall girls stare at me though other girls often do it. That's the reason I don't approach them though I'd like to. Is it because they are insecure and not because it's a turn off for them?
