Most Helpful Girl
Find out a key problem to start from there maybe it's not just her, who needs change it could be possible you need one too. But it's good you two have differences because honestly if everyone liked the same thing it would be hella boring, as for intimacy switch up a little do a few things she likes and then do few things you like. Being carefree is also a good thing because you can help her tighten up if things get to far and she can help loosen you up too it's mainly about balancing your relationship. The person your with should have qualities you lack in same with her.
