This is good if you share a room or a bed and can't get to sleep. Lie on your side, grasp your shaft firmly with one hand, and use your thumb to lightly stroke the head, making circles around the urethral opening. Don't move the hand at all – just the thumb. Focus on controlling your breathing and keeping your body completely still. Maintain a steady speed and resist the urge to pump the shaft with the hand or to make the thumb go faster. If you start to produce Cowper's gland secretion, rub it onto the head, keeping the same speed and rhythm. You may relax the grip on the shaft from time to time to use one or more fingers with the thumb to stroke and squeeze the head in different ways, being careful not to speed up. Then return to the tight, stationary grip. If you increase the pressure, slow down the speed. You can also change from circular to a back and forward movement. Eventually each stroke will cause the penis to tremble as if you are plucking a guitar string. The temptation to speed up or to pump the shaft will be strong – but if you can maintain a slow, steady rhythm you will be rewarded with a long period of intense ecstasy as you hover on the edge of ejaculation. When you finally have your orgasm it will be long and powerful, leaving you completely drained and tingling all over.
