I want to explore more of my kinky side

I have quite the kinky immagination and I'd really like to explore a little more. We've tried light bondage and such but never anything involving whipping, role playing, etc. I'd really like to play the dom position but unsure how to go about it. How did you start out? Can someone give me an example of what you do/say? What are some good toys? Your help is much appreciated!
