Good report. Most guys would have caved long before.
I've been loosely using Tinder for a few months and found the best results come from being the nice guy, so to speak. I can't tell you how many girls have given me the "all the guys here just want sex" rhetoric, so going sexual too soon is the quickest way to be blocked or ignored. That doesn't mean these girls aren't looking to hook up, but they don't want to feel like a "booty call". They want to rationalize it as "he was a nice guy, we met up, and it just happened". So play it from this angle.
My standard approach is to message with one of my copy-and-paste openers to get them laughing, play the part of NOT looking to hookup, keep the conversation light and witty, don't ask too many questions, and move to texting once some rapport is built. I usually say something along the lines of "I swear nobody looks like their pictures on here, you should text me a few more". This literally sucks them in and they'll want that validation.
The brilliant thing about Tinder is most of these girls are chatting with you while they're at the bar on a Friday/Saturday night, they're open minded, looking for fun, and bukowski played his hand 100% correct suggesting an after-party at his place. Post bar meetups are the quickest and easiest way to get laid in 2014.
Every girl is different though, sometimes you just have to feel her out and fly by the seat of your pants.
