AUncut10in: I am not sure I can explain how to do this. It is much easier to demonstrate, but I will try. I can have multiple orgasms. By that I mean I can shoot just one shot of cum and then stop there. I can then keep jerkin off and shoot a second lone spurt. Usually I can cum a total of 7 times in one session. Each time, there is an orgasm without loosing your erection. Not sure how I figured out how to do this. but it is all about control. It is definately easier to do this while masterbating. So practice doing this first by yourself. The way to do this is when you feel the ejaculation starting, you have to totally relax.You will feel that contraction but already be relaxed. It is at that point you have to stop the orgasm. The cum will shoot out, and the orgams will be finished. but because you have not shot your whole load, you can keep jerkin off and be able to repeat the process. It is easier to control if you have cum within a day of practicing this exercise.
I was talking to a friend of mine, who was getting married in a couple of weeks. We were talking about this very subject. He really wanted to accuire this ability. He ended up talking me into a demo. (I think he was also very curious about how I looked hard. He had seen me soft before and made several remarks ) So we both jerked off together. I could talk him through it, ask him where he was in the process, and tell him exactly what I was feeling. The first couple of times we did it, he totally shot his whole load, but then the last time I did it with him, right before he got married, he was able to cum twice. We havent jerked off together since he got married, so I am not sure if he was able to get better at it.
Hope this helps. If I am not quite clear, let me know.
