Like Kayla said, communication is very important. you have to be able to speak openly to him about what you want from him and how you feel about it. In return, you have to be able to listen and understand when he speaks to you about his feelings as well.
Go Slow. Rome wasn't built in a day and neither is a BDSM relationship. You both need a little educating on a lot of different things, but start out with what interests you. Google 'BDSM Checklist'. You fill one out and ask him to fill one out. Compare both of your interests and talk openly about them.
Get your hands on some great reading material. SM101, The Topping Book, The Bottoming Book, Screw the Roses Send me the Thorns. EF carries some of these.
Fetlife.com is a source that some find to be very educational.
I would suggest joining your local kink community.

Good luck and HAVE FUN!
