@Awol69,
If you want to be with her, focus on what's working for both of us.
Talk to her. About anal, about sex generally, about why you're together, about what turns her on, about what turns you on. All that good stuff. It's cliche to say, but a lot of good sex starts in the brain, so you can figure a lot out by talking.
and yeah, anal sex. it can be a good part of a couple's sexual menu but if that's all it's about - boring <shrug> gotta have variety on the menu to keep things going
