What you are experiencing, wanting to learn how to be a good dominant for your bf, is extremely common. I recommend joining www.fetlife.com and reading the group topics there (fyi I am ted_subby on FetLife), especially in the Novices & Newbies group. There are many femdom groups there and also don't hesitate to ask for advice.
Most of all, though, talk with your bf in detail about what he wants. There are many different types of submission and it's not safe to assume that what you read would apply to him.
In addition, here is a link with good and comprehensive information: http://akashaweb.com/updates/GoodGirlsFreePreview.html.
