Why don't you just stop asking her all together and decline anything sexual on the next occasion it comes up. That might create some waves

.. HEH..
hrmm.. but seriously, I dont feel "some day it will happen" is such a bad answer. Shes just not ready, but shes also indicating that one day she will.. so, its possible. She could feel very ready tomorrow and that will be the day it happens! my bf had to wait awhile for me too. Since you guys make out and do everything else but penetration, I can't see how it could be so bad without intercourse. I don't want to intrude, but have you fingered her before? fingering is.. not too far from intercourse.
You'll be alright.
