If she expects you to do something ultra-romantic that will feel like pressure for sex, why not do a 180 that will jar her out of her rut? For instance, suggest that you take the kids to Chuckie Cheese for your anniversary or get annoyingly drunk (if this is out of character for you) rather than annoyingly perverted. I find that even if doing a 180 is the opposite of productive in the short run it still ends up being helpful in the long run because it gives both of you a different perspective from which to view your relationship.
