dominate and submissive?

I've been seeing this guy for awhile and I'm ready to finally have sex with him but he's into girls who are submissive to him during sex which I'm totally into and have always wanted to try it I'm just kind of nervous to try it because it's like opening the door to a whole new world for me. Does anyone else have dominate and submissive sex with their boyfriend/husband? Which one are you? How is it? Do the dominate ones do most of the work? Also am I the only one who gets SUPER turned on when a guy tells me what to do or bosses me around I feel like that's not normal or at least not that common lol.
