This is a start-stop technique that you can make go on for as long as you can stand it. Some are able to do this for hours going through waves and waves of orgasmic pleasure with no ejaculation so it can last for literally hours if you have the time.
Get a good hard erection with plenty of lube and stroke your penis in any way you wish, but stay away from the edge before ejaculation. Just get aroused and very hard — no more. When you’ve settled in, have control of your arousal and can stroke easily without coming close to the edge of ejaculation, concentrate on your muscles around your anus and the base of your penis and one-by-one relax them. Consciously let them go. Sometimes you have to squeeze them to identify them and then relax them. The important thing is to relax each and every muscle.
Now, lay back with your head on a pillow, slightly pull your knees up and spread your legs. Hold your erect penis shaft lightly with one hand and cup your other hand over the head of your penis, rotating your hand around so that the palm of your hand only contacts the head or glans of your penis. Don’t stroke any other part of your penis — only the glans with your palm.
You will feel a very intense sensation and the temptation will be to grab your penis and pump. Resist the temptation and relax those muscles. As long as you stroke this way, you are not likely to ejaculate. If anything, you might urinate without realizing it so keep some tissues or a towel handy. If you feel you’re coming really close to ejaculation, back off a bit on the stimulation and let the urge to ejaculate pass. Then continue.
The head or glans of your penis shrinks a bit when you stroke this way. After a couple minutes, the really intense sensation subsides and then it moves into other parts of your body. Keep going. Keep stroking and imagine the energy moving from your penis up into your stomach and into your shoulders and arms and head. Then down into your legs. Keep stroking. Relax those muscles. If you get close to ejaculation, slow or stop, get control and then start again. Only the head. Only the palm of your hand.
Your first time, you’ll probably only be able to do it for fifteen or twenty minutes. Later, you’ll be able to do it for an hour or even two. The orgasmic energy will move through your body and you’ll discover a sense of being you never knew was possible. You’ll feel light, healthy and free of stress.
You can end with ejaculation if you want, but you don’t have to. A lot depends on your age, recovery time after ejaculation and mostly on your state of mind. You might find that you feel full of energy and life if you don’t ejaculate. It’s up to you. Experiment and enjoy!
