This is quite easy to do. You rub until you reach the point where it feels as though you want to pee, and then you stop. At that moment, if you then wait, you get an ejaculation but no orgasm. You rest and then work to that point again, and again you stop - and so on. I can do it at least half a dozen times. But when you DO hit the orgasm, your penis nearly explodes! Try it: it's good fun, though rather messy.
