Yeah at least you realize there is no investment since it is just tinder. I don't have tinder so correct me if i'm wrong but isn't it just a few of your fb pics and a custom tagline of some sort? In this case it mostly comes down to profile picture since you can only talk to her if she pushes like. Make sure your profile pics make you look fun- lots of different venues, lots of social proof. When you do get a like, make that first line something memorable. Look through her pics (not just at her tits lol) for any clues as to what she might want to talk about. Get that first clever line in, analyze her response, act confident (which you did come across as more confident than not in your original post), and slowly lead the conversation in a romantic direction. It is ok to pick up the speed if you are getting the right signals. Girls use tinder and similar apps and sites for two reason 1) entertainment 2)to meet guys (in that order). Sometimes these goals cross, so remain persistent.
As far as what to do after the open- elicit value and then display value. There are many articles online as to how to do this if you haven't looked through them already. Basically you want to show her you are fun and she should talk to you, all while you figure out what she needs/wants in life/a lover, and the project that back at her. I'm going to outline a really crude example for you.
you: Do you like a guy who can make the first move?
her: yeah doesn't every girl?
(half the time she won't even write back so this scenario is for when she does)
you: well I've known a couple girls to make the first play
her: oh really, you must be some kind of player or something
you: I'm whatever you want me to be
you: do you have a boyfriend?
her: no
you: oh so who do you watch romantic comedies with ?
her: I watch scary movies
you: oh so you like a thrill?
her: you could say that
you: would you ever go bungie jumping?
(the above line is my crude example of eliciting value - if she says no, you know she isn't really that wild and can start projecting a comforting/strong/reliable)
her: hell yes
*you: tell some story of something crazy you have done
(the above line is a crude example of displaying high value. Basically you found out she is a crazy girl who want something exciting and fun, so now you tell her a story about how crazy and fun you are)
so the point here is that you ask her questions or make statements that will give you clues as to what kind of things she is missing in life all while keeping things fresh and interesting. This in turn leads the future questions and statements you make. Sometimes she will seem bored, sometimes she will seem busy, sometimes horny. I find most girls want to be entertained and feel safe. Find this out as subtly as possible and then just as subtley project that you all these things or can solve all her problems. Then you can joke with her about stripping for her and by this time you are her dream guy and the thought of you naked makes her wet.
So in closing, I think you made a mistake with your opener. The very first thing you said to her was trying to commit her to hanging out. You also made a mistake by escalating it too soon/the wrong way. Like I said earlier, it is perfectly fine to make sexual innuendoes early in the conversation, but you need to do this when they are more interested and/or to weed out the girls who aren't down to fuck. Otherwise, I admire your attempt and you are on the right track seeking advice. You are going to go far!
Good gaming my bro
