Making the most of an uncircumcised penis.
Taut Nylon
Pull back your foreskin to expose the glans (head). Then stretch the leg of a pair of pantyhose, or a nylon stocking, between your hands so you have a flat band of nylon. Keeping it taut, rub it up and down the edge of your glans or across the frenulum (the extra-sensitive area underneath). It can be so intense it's like torture.
Fill your Foreskin
Sit in a tub full of warm water, and fill an ear syringe or some other bulbous apparatus (such as a turkey baster) with warm bath water. With your foreskin over your glans, lightly pinch it over the opening to the syringe tube, and squeeze the bulb to fill the foreskin; then release in order to suck the water back into the syringe. Repeat doing this until orgasm. You can vary the timing of the squeezing from slow to fast, as if you were humping. The sensation is much like vibration, and the warm water is the kicker – plus, it is a no-mess cleanup, because the semen gets sucked into the syringe with the water. It's a very intense feeling. Another tip: Keep the flow rhythm going throughout the ejaculation, as it intensifies the already skyrocketing orgasm. The orgasmic sensations from this technique can be very intense; in fact, be careful, as they can even be slightly painful.
