Fetlife.com is the best site for resources. It is a social networking site like Facebook, and they have many groups and threads revolving around BDSM for newbies and experienced users alike.

Look for the "Novices and Newbies" group and they have thread after thread covering everything you are curious about.

It's actually quite common to have abuse fantasies. Most people have thought about it every once in a while, some more than others. It does not necessarily mean you will act it out IRL or in your sex life, but it's normal to feel that way. Perhaps you are seeking a sense of power that you don't have IRL, or the opposite, you are seeking submission because you have too much power.

I really recommend trying out the site if you have a serious interest in BDSM.
