Eskwire, what was that? Like needy guys post vs. wanty guys posts?
It seems like you are confusing demostrations of high value with demostrations of desire for a woman.
Being a "cool" guy is not necessarily related with showing desire for a chick.
Desire in this case, means sexual appetite in a passionate way. Passion is always good as in living your life with passion. Passion is always bad whan you get too passionate about a girl you just met.
There's a problem with this disscusion: Being wanty, needy or passionate can be equally bad, or good (well, needy is always bad). Sometimes people picks words because they sound pretty and thats the case with the use of "desire" here.
Desire is just plain old lust (horniness). (just google desire)
Not being needy is a thing you learn out there in the field. Basically out of trial and error. Having a friend to let you know whan you are being a push over helps a lot.
Women loved to be wanted (who doesnt). Thats a know fact. Learning how to use that in your favor is the goal. Conveying "desire" is a vague thing.
One of the main things to consider is timing. A dumb ordinary and over used compliment like "you have beautiful eyes" can be surprisingly effective if used at the right moment.
I'm not talking IOI's here, this is beyond just being interested. Is making a woman feel like desired, beautiful and if you are good enough, worthy.
With most girls its really easy. Just hitting (properly) on a normal girl (HB6 to

does the trick, she'll be flattered.
With hotter women, it is not as easy... because they are used to be desired. With the absolute hottest ones, (that have some brains and charisma too) you have to offer them something unique. Thats hardcore stuff, not for the unexperienced, and to be honest luck plays a huge role with this girls... sometimes you dont have to do anything, sometimes it doesnt matters what you do... to increase your chances you have to try a lot. And that applies not only to the hottest ones, in general more experiments increas the probability of a success.
I'm gonna post about this in further detail later, I wrote a little bit about a ton of things here, and thats not very helpful for the guys that want to learn...
