Forget all that "obey her" crying. Nothing good can come from it, that way of thinking is nothing but a trap.
If you are willing to do it, then do, for your own sake! Just do it for the right reasons. Go after your happiness - just be sure it's there where it lies. Get a taste of what it would be like that life, but do it alone, just by yourself at first (I know it's something completely different, but get the closest you can get as long as you feel comfortable).
And, in fact, maybe Kripter is right. That could be true, or she's trying to mold you - for her better (or worst) interests, for inflated ego reasons (as to how "sexy and powerful" she is and how she can "tame" you into a beta-male), or even she is tricking you for further blackmail material (for reasons above discriminated). After all, there is quite a handful of women who like to be put on a pedestal and be worshipped and show themselves as manipulative, controlling b****es.
For example: www(dot)brassiered(dot)com(slash)brassiered(slash)whatis(dot)html; that Karen Salmansohn (from that "man taming" guide of hers - yet, somehow, thanks to feminism, she managed to succeed. Why did I know it beforehand it would end like that?)
Just be sure you know her reasons for asking this, try to rationally see if there is not just some attittudes of you bothering her (and the other way around, also), and choose your way of life wisely, based on the right reasons - and the first one is what is good for you.
