It boils down to jerking off as much as you can until you almost cum, then hold back and start jerking again. Preferably to porn that cuts from clip to clip and what I like, captions that reinforce porn addiction and more gooning and edging. A cycle.
Gooning is repeated masturbation to almost orgasm, then stopping, and starting again, until you or another person is in a trance-like state of ecstasy.
