HUm.....well, I am a guy and I give you some thought through my perspective and hope it helps. My partners use to call me "sexy", so call him "sexy". Then when you are making out again, make some moaning noises and what not. Then whisper things like "ahh" and "ohh". Or how about, whisper "dam (his name), your so dam good". That's about all I can tell you, lol. Yup, all my partners did was moan and say things like I just mention. Hope it helps.
Good luck!
