Just before a male ejaculates, there are premonitory sensations marking a point of no return—when ejaculation becomes inevitable. Some therapists call this the “moment of inevitability.” Once that threshold has passed, it is too late to delay ejaculation; it then occurs beyond the man’s control.
Masturbation helps men learn to recognize the "moment of inevitability" just before orgasm and helps teach them how to avoid premature ejaculation.
