Why not try this: Make love to him exactly like you'd like him to make love to you. Of course there are some anatomical differences, but you can come pretty darn close.
It might help you, because you could fantasize that what you are doing to him is being done to you. And it might help him in terms of desire/satisfaction. Might be just the way to get the ball(s) (sorry, couldn't resist) rolling.
I have done this a few times and it does actually work. I have to be super horny (and maybe a little drunk) to pull it off so that we are both sexually satisfied. I think maybe I do rely too much on my partner to jump start my desire. An aggressive man in the bedroom gets me hot in about 2 seconds, so it makes sense I would prefer that. But when I have to do it basically myself, well, I can get there, but it takes longer. LFL
