Oh. Damn. I saw this before, but life has been crazy, and I never got back to you, even though I intended to.
So, books, resources, etc...
The problem is, your interests are all across the board: Dominance, topping, bisexuality... That's a HUGE lot of information.
Dominance. I'd like to point you to my writings. Both the books and the free stuff on Tumblr. I live this, and I focus very much on realism, as well as the mental aspects of dominance. RS has a book list he links to in his signature file. That's a good place to go as well. The other site has many amazing groups with a lot of experienced people and good information. These forums are a good place to post questions. Stay away from Elise Sutton and her like. It's pretty clear to most everyone that it's a male writing wank-fodder.
Topping. There is not much in my opinion better than actual hands-on learning for this. You can grab a book or two, depending on what you want to learn, but classes and practice are going to make up 90% of what you have to do. For example, my primary physical acts of topping are spankings and electric play, including micro-branding. I learned to spank in NYC from a gay leather daddy, and I learned electric play and micro-branding by asking questions, watching demos, being guided, and practicing under a watchful eye.
Bisexuality. Are you exploring this as part of your dominance/topping? Because that adds layers. If you are just exploring the sexy parts of it, find a willing partner, then just go. There is no better way than to dive in, being 100% honest with yourself and your partner about where your head is at.
Ask questions... it's easier, really to answer specific questions than to try to fill someone in on things that take years to learn in an overview.
