There is one guy who completely focuses on that niche, he has a network of Femdom blogs, he will be the best place to get a link from, all the major Femdom sponsors use him for links/traffic. If there's anyway you can get a link from his one of his blogs it will put your new site on the map. I saw him posting here the other day, you could try sending him a PM.
