Powder your Arm

While lying on your back, shake a good quantity of talcum powder or cornstarch on your erect penis and adjoining area. Then rub it with the underside of your forearm. You will find that the powder is a good lubricant in conjunction with this rubbing technique. During the session, turn over and hump your arm; then return to lying on your back. You can slow down the approach to orgasm by avoiding your glans (penis head) when you rub. Using your imagination will reveal many ways to fine-tune this technique for more variety.
