Hey.. I just had many years of marraige without feeling anything with penetration. Now I know..... you should try using your fingers in her. It's very possible that the in and out is not hitting the spots that feel nice to her. learn a technique where you can use your middle two fingers in her with your palm facing up to the ceiling and roll your fingers around in circles like in a stirring motion.. then switch around to rubbing and poking different parts on the sides and then back to stirring motions.. get to know where and what feels the best through your experiences.. good luck.
It still could take a few months before she cllmaxes because she needs to find how to relax.. let her do that.
