Looking for more Information on BDSM Relationships

As I explore my own sexuality I find there is more and more I don't know. Although far from submissive all the time or in real life, I am at times quite submissive. A Switch. I would love to read more about the dynamics of BDSM from the relationship side or the Dom side. Can anyone recommend any good books or blogs? I already read 24.7 and PixiePie but those are both written from the submissive side.
