I didn't know how to maximize my masturbation pleasure until my best friend showed me how. I used to just go at it and come as fast as I could because I was impatient for the great release of orgasm. But when we had sleepovers when we were 13, my friend did it for a long time -- so long that I sometimes fell asleep waiting for him to finish. He did it so long that he always had to renew the lube he was using. It was a real turn-on to masturbate together because I liked to watch him, but after I was finished, it wasn't a turn-on with him doing it alone. It was almost irritating, and a little embarrassing to watch.
I used to think he took so long because he had a hard time reaching orgasm, but one day he got frustrated with me for getting done so fast, and said I was missing the best part, that the buildup leading to orgasm could be as good or better than the orgasm itself if I took it slowly and 'edged.' He offered to show me, and did it to me for nearly an hour, slowing down and stopping for a moment each time he sensed I was getting close. The feeling of him manipulating my penis was wonderful, and I could tell he was enjoying it because he had a boner, too. He had me on such an edge of pleasure that I couldn't stand it anymore, and had the biggest and best orgasm of my life, and a really messy one, too.
He was so turned on by the experience that he stroked himself after I was done and came almost immediately. I asked him how he'd learned that, and he said his older brother had taught him four or five years before (meaning he'd been masturbating long before I was). He made me promise I'd practice self-control, and I did as well as I could from then on. Sometimes I can hold off for an hour, but sometimes I lose it earlier. But in any case, my masturbation feels better than ever. Of course there are times when I don't have enough time or privacy for a long session like that, so I do it quickly like before, but I always vow to make up for the difference as soon as I can, and I've never reneged on that promise to myself!!
I've had the chance to teach that technique to two other people -- a friend and my younger brother, and I'm happy that I could. If more people read the stories on this site, everyone could enjoy their masturbation better.
