Virtually all males masturbate, though some more frequently than others. Masturbation usually continues throughout adulthood, even when other forms of sexual activity are available.
Most adolescent males are very embarrassed their self-stimulation activities.
Only a small percentage of male adolescents discuss their masturbation even with close male friends, and most are terrified that their friends will find out. So, many adolescent males learn to get it over quickly, to minimize the chance of being discovered. Only later in life do they learn that the ability to delay orgasm is very important to learn in order to maximize sexual pleasure. Although as a man ages, the frequency of masturbation tends to gradually decline, but continues even for most married men. Some men believe they should not do this when they have opportunities for sexual activity with their partners and therefore try not to masturbate, in part, because they believe that masturbation implies partner rejection.
