If you got a car man..... I got loads of ideas for you d00d....
Heres one, Did this one like a month ago
Take her to the movies, simple movie date....
Then when you get into the car, dont go no where, turn the heat up on full.
Tell her how pretty she is, start a conversation. Then make a very unexpected kiss....
If she likes it, move to the back seat.
Tested by me... It works!

And no people! Im not telling them to have sex! Its just making out, its not comfortable in a car...

Good Luck man.
I could throw you more ideas if you dont like that, im filled with em. I have to do something like that almost everyday
