I think you have to accept the possibility that she just doesnt like it ...
I think it can happen but you 2 will have to try something a little more involved to get her in the mood to explore so many different avenues of pleasure.
And about tha anal thing ,it is very erotic and if she will try it she will like
I personally love to give facials but some women just dont like the mess.
So explore different scenes and turn ons for her to try and bring the wild side out...
I have found someone to bring the sexual beast out in me and that was amazing .so good luck man
