MASTURBATION<xml><o></o>
Masturbation is usually a normal precursor of object-related s.#.e.#.xual behavior. No other form of s.#.e.#.xual activity has been more frequently discussed, more roundly condemned, and more universally practiced than masturbation. Research by Alfred Kinsey into the prevalence of masturbation indicated that nearly all men and three fourths of all women masturbate sometime during their lives.<o></o>
Longitudinal studies of development show that s.#.e.#.xual self-stimulation is common in infancy and childhood. Just as infants learn to explore the functions of their fingers and mouths, they learn to do the same with their genitalia. At about 15 to 19 months of age, both s.#.e.#.xes begin genital self-stimulation. Pleasurable sensations result from any gentle touch to the genital region. Those sensations, coupled with the ordinary desire for exploration of the body, produce a normal interest in masturbatory pleasure at that time. Children also develop an increased interest in the genitalia of others—parents, children, and even animals. As youngsters acquire playmates, the curiosity about their own and others' genitalia motivates episodes of exhibitionism or genital exploration. Such experiences, unless blocked by guilty fear, contribute to continued pleasure from s.#.e.#.xual stimulation.<o></o>
With the approach of puberty, the upsurge of s.#.e.#.x hormones, and the development of secondary s.#.e.#.x characteristics, s.#.e.#.xual curiosity intensifies, and masturbation increases. Adolescents are physically capable of coitus and orgasm, but are usually inhibited by social restraints. The dual and often conflicting pressures of establishing their s.#.e.#.xual identities and controlling their s.#.e.#.xual impulses produce a strong physiological s.#.e.#.xual tension in teenagers that demands release, and masturbation is a normal way to reduce s.#.e.#.xual tensions. In general, males learn to masturbate to orgasm earlier than females and masturbate more frequently. An important emotional difference between the adolescent and the youngster of earlier years is the presence of coital fantasies during masturbation in the adolescent. These fantasies are an important adjunct to the development of s.#.e.#.xual identity; in the comparative safety of the imagination, the adolescent learns to perform the adult s.#.e.#.x role. This autoerotic activity is usually maintained into the young adult years, when it is normally replaced by coitus.<o></o>
Couples in a s.#.e.#.xual relationship do not abandon masturbation entirely. When coitus is unsatisfactory or is unavailable because of illness or the absence of the partner, self-stimulation often serves an adaptive purpose, combining sensual pleasure and tension release. Kinsey reported that when women masturbate, most prefer clitoral stimulation. Masters and Johnson stated that women prefer the shaft of the clitoris to the glans because the glans is hypersensitive to intense stimulation. Most men masturbate by vigorously stroking the penile shaft and glans.<o></o>
Moral taboos against masturbation have generated myths that masturbation causes mental illness or decreased s.#.e.#.xual potency. No scientific evidence supports such claims. Masturbation is a psychopathological symptom only when it becomes a compulsion beyond a person's willful control. Then, it is a symptom of emotional disturbance, not because it is s.#.e.#.xual but because it is compulsive. Masturbation is probably a universal aspect of psychos.#.e.#.xual development and, in most cases, it is adaptive.<o></o>
Several studies found that in men, orgasm from masturbation raised the serum prostate-specific antigen (PSA) significantly. Male patients scheduled for PSA tests should be advised not to masturbate (or have coitus) for at least 7 days prior to the examination<o></o>
