Serious help needed with hb9+!

I already asked question before about her.. but now it gets to the point where i feel like nothing moves but im a complete loser.
I studied math with her today, everything seemed fine.. then we started walking and she was going towards the buses. i said "you know, its been on my mind the whole weekend, i was thinking about us, and i thought, i want it to be more then hanging out after class.. what do you think?"
her: "well.. i dunno.. maybe... i just want to take it slow.."
me: "thats fine, im not rushing anywhere.. all i want is dinner with you"
her: "okay.."
-then we set up the date

I drove her home (my willing.. she said that i dont have to and she would feel bad but i said that her notebook is getting a ride and if she wants she can join)
when we got there, i didnt see her mom's car which means the whole house is hers.
she gave me a hug and turns around to get out of the car.. i said "no kiss goodbye?"
she turns around give me a kiss on the chick and gets out..
then i said this: "just so you know, i have a rule, i dont usually have sex with women on the first day" (something along the lines to make her comfortable)
she goes: "obviously.."
i turn off the car and get out too and as i do this i say "hey i want to ask you something.."
her: "what.. where are you going.. whats your question?"
me: "you arent going to show me around the house?"
her : "no my house is messy, next time.."
me: (after thinking to myself) "okay thats fine, i respect that.. come give me a kiss then"
her: -walking around the car towards me and said "i will give you a hug" -and she does and then pce..

what am i doing wrong?

i think you are pushing it too much and making it look more forced. try to make things flow more smoothly. every time when im in a situation i think how can i make this more smoothly. try it and you will improve a lot.

body language is important. how is she reacting? i think you should flirt more and move towards her in a more physical way instead of talking your way into things.

Remember, we are attracted towards the things we have to work for. You were offering her the kiss and offering her the ride and offering your time. Don't offer these things. Make them sound appealing, yes, but never ask or demand for them. Make them elusive.

On that same note, the "I don't have sex on the first date" line should only really be used when you're actually on the date and sex might actually be an option. If you guys weren't talking about sex, then it sounds too obvious.
