The way she reacts after she sees your post will say volumes. At the least you will need to discuss it. Communication is all important in a relationship of this sort. Remember, however, that you wish to be the dom in this relationship. It sound almost like you are begging her. Not good.
Perhaps she is waiting to see how you react. If, as you said, you tried this when you first met and it failed, you will have to win her trust back. That is not something that will be quickly achieved.
What Kats said above is also very true. This way of life must be a two way street. A nudge is fine, but a push is no good. Posting may help you get a discussion started. That is a great starting point.
One last thought, does she think that she wants to be the dominant one?
