You'll probably want lubrication for this one, and you'll need to start out by getting yourself erect. Once you're ready, place the palm of your hand atop your penis so that it's trapped between your hand and your stomach. Rub your hand in wide circular motions, like you're rubbing your belly. You'll probably get best results with this technique if your hand, penis, and stomach are all well lubricated.

This is another technique that utilizes the sensitivity of the perineum (the skin between the testicles and anus) and prostate. Sit at the corner of a bed, with your legs hanging over each side. As you masturbate, you can lean forward onto the corner of the bed, which will put pressure on your prostate through the perineum. You can also try sliding back and forth or bouncing gently to change the sensation.
