What about trust and respect...
If she is a attractive girl she may just be fed up with getting the hard word being put on her.
Don't be in an all fired hurry to close the deal...that just puts you in the same class as all the other guys that have chased her.
Try Wooing the girl....a flower just for her..it might be a daisy or a rose..open doors, hold her hand, tell her she looks lovely, open doors....a small peck on the cheek to say hello...leave a short brush of the lips for good night and tell her then that you really enjoy being with her, it will turn into full scale kissing if the timing and chemistry is right.
It doesn't have to be a huge grand gesture..it's the small thoughtful things that mean the most.
