I found out about a technic somewhere that I've never heard of. I wonder if anyone else has heard of it. He called it the "Dribbler technic". It's like the stop and go technique, but brings it a little farther. you keep going until you can start to feel the cum coming, and then you stop. You have to stop at the right time, and you keep going so far that the cum will actually "dribble" out, but you haven't really orgasmed yet so you can keep going, using your cum as a lubricant. I tried it, and it worked perfectly. I kept going, and stopped, and let the cum flow out. the cum only dribbles, or flows out because you haven't fully orgasmed yet, so it doesn't shoot out with the force of an orgasm. so, when I tried it, the cum just kind of flowed out, and then I touched my penis, and found that I could keep going. I had to yield to the next orgasm. I didn't have the time to keep going anyway. but this guy who talked about it said that he went as far as 10 one time.
I've done this before. It takes a good sense of the sequence of events and when they're going to and about to happen. Unfortunately, I personally have to wait a long while after each time I do this or I'll just orgasm within a few seconds of going at it again. If I had the time and the self-control I would do this more often.
