Get him turned on, tempt him more with things, and lead him on.
Well what my girl does to me in order to get me on top of her is => She'll lay out on the bed and only be wearing a thong/ just be naked, wave me over and thats actually pretty much all it takes. Most guys like to be on top but we also like our girls to take control sometimes and get on top and take us on a ride ;)
Well, you have to grab onto his banana in order to make him horny.
