Because you have to build it.
Look, you have to look it at like they do. They have armies of thirsty men who have all been told their whole lives to 'be yourself' or 'say something nice about her' to approach women.
Hell, look at all the posters here who have told you to compliment her first.
So she's inundated with tons of the same old messages of 'you're pretty' or 'I like your eyes' or 'nice tits'.
But in you come at her totally innocent in the beginning, simple statements of 'I see you like coffee from your profile, coffee here in the states tastes so much different than coffee is columbia' or 'you like dogs, I wish I still had my 3 dogs when I lived for a while in russia" or whatever.
This achieves a few things.
First, your not like every other guy who hits her up as you don't show interest in her already off the bat. That's special and different than other guys in the past.
Secondly, your interesting in the fact that you have a story. Places you've been, things you've seen and that's exciting to women.
And 3rd, without telling her more than passing info about your dogs, coffee or beaches, it shows that you don't find her interesting enough to elaborate on coffee beaches or russia yet, and she has a deep seated desire now for her to validate herself to you to get to know more about you.
And all of a sudden bam, she's chasing you for interest versus the other way around.
Women love sex and want it just as much as we do. But how they get there is far different than we do. We have all been lied to our whole loves about how to atttact women, and it shows on things like tinder. Stand out. Be different and you'll be suprised at how successful you become.
