Thank you so much for the replies so far. All were helpful. (I'm sorry about the typos in my original post, by the way.)

IDCrewDawg's personal experience is informative and helpful (and I see the point re: dominant vs. top), and nerameshu and fetishdj both offer good angles regarding selling someone on the benefits of being a top. I am thinking that if he understood that he could have sex very quickly if he just pushed the right (and not very difficult) buttons (ordering, slapping, etc.), he might be happy to go this route, though of course, I have been giving him sex most of the time, anyway. Still, I can't help but imagine he'd be delighted if he knew he could have things like oral whenever he wanted, even outside of the bedroom.
