He wants you to take control, he wants you to tell him what you want him to do, he wants you to do exactly what you want to do. He might want you to be a bit rough with him, he might want you to do something which involves him sitting back and having absolutely no say in what you're doing, perfect example of something like that would be something slightly more kinky, handcuffs and such.
My boyfriend likes it when i'm more dominant, I do some of, or all of the above and he really enjoys it.
