Masturbation
Masturbation refers to the behaviour where a person actively manipulates his or her genitals to gain sexual pleasure.
With the approach of puberty, the upsurge of sex hormones, and the development of secondary sex characteristics, sexual curiosity intensifies, and frequency of masturbation increases. Adolescents are physically capable of coitus and orgasm, but are usually inhibited or prohibited by social restraints. The dual and often conflicting pressures of establishing their sexual identities and controlling their sexual impulses create a strong physiological sexual tension in teenagers that demands release, and masturbation is a normal way to reduce sexual tensions.
In general, males learn to masturbate to orgasm earlier than females and masturbate more often. An important emotional demarcation 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 sexual identity.
