I am one with the stop/start thing. You can gently rock away, and keep sliding out to rock the base of your courting tackle against her tingly bits when you feel a little extra tingly yourself. A smooth transition is the key. Coupled with a lot of you lifting and stroking her body with your hands, and you working your mouth and throat up and down the territory between her ear, down her throat, and past the breasts right to the belly button (an occassional dip for a taste is never amis), will make the whole thing a whole body experience. Breathing, moving together, and a bit of sweet talk . . .
Rock on, Johnny
