The key is to really know yourself and what you feel like leading up to an orgasm ... and then lighten up your touch a bit, enough to stimulate yourself but not send you over the edge, and then pick up the pace again ...
I'll rub the head mainly until I get close, then to "bring myself down" a bit I'll work more on the shaft and balls until I don't feel like I'm close to orgasm anymore, then work on the head again. Lasted hours this way, though when I finally did shoot I ended up hitting the wall 3 feet behind my head.
