if there aren't Dommes in your area, there is not much you can do. you will just have to focus on making yourself a good sub in the meantime, so that way when a Domme in your area becomes available, you are worthy of being of service to her. That, or move.
Instead of sitting idley, try reading books, stories, articles on various aspects of the lifestyle. go to Munches, Parties, Demos and Fairs. Learn the theories, familiarize yourself with the kinks, and understand yourself. Nothing worse than a sub who wont take the time to identify his interests, desires, needs and limits because compatibility is important for sustaining a relationship once you find it.
best of luck
