about masturbation

Self-masturbation is self-stimulation with the intention of causingsexual arousal and, generally, orgasm (sexual climax). Most masturbation is done in private as an end in itself but is sometimes practiced to facilitate a sociosexual relationship.
Masturbation, generally beginning at or before puberty, is very common among males, particularly young males, but becomes less frequent or is abandoned when sociosexual activity is available. Consequently, masturbation is most frequent among the unmarried. Fewer females masturbate; in the United States, roughly one-half to two-thirds have done so, as compared to nine out of ten males. Females also tend to reduce or discontinue masturbation when they develop sociosexual relationships. There is great individual variation in frequency, so that it is impractical to try to define what range could be considered “normal.”
