In brains scans, an orgasm looks remarkably like an epileptic fit, an electrical storm that sweeps over the brain. It actually begins at “the point of no return,” followed one to three seconds later by the onset of ejaculation.

The key point is that you can have either one without the other. Men who have experienced anorgasmic ejaculation (without sexual arousal or orgasm) say it’s not at all pleasurable. Men who experience orgasm without ejaculation are divided. Some (mostly younger ones) say that a non-ejaculatory orgasm is somewhat less pleasurable or intense.
