Adolescent sexuality is sexual feelings, behavior, and development in adolescents, and a stage of human sexuality. Sexuality is often a vital aspect of teenagers' lives. The sexual behavior of adolescents is, in most cases, influenced by their culture's norms and mores, their sexual orientation, and the issues of social control such as age of consent laws.
In humans, mature sexual desire usually begins to appear with the onset of puberty. Sexual expression can take the form of masturbation or sex with a partner. Sexual interests among adolescents, as among adults, can vary greatly. Sexual activity in general is associated with various risks including unwanted pregnancy and sexually transmitted diseases including HIV/AIDS.
The risks are elevated for young adolescents because their brains are not neurally mature; several brain regions in the frontal lobe of the cerebral cortex and in the hypothalamus important for self-control, delayed gratification, and risk analysis and appreciation are not fully mature; the brain is not fully mature until age 25. Partially because of this, young adolescents are generally less equipped than adults to make sound decisions and anticipate consequences of sexual behavior, although brain imaging and behavioral correlation studies in teens have been criticized for not necessarily being causative and possibly reaffirming cultural biases.
Adolescent sexuality begins at puberty. The sexual maturation process produces sexual interest and thought processes. Subsequent sexual behavior has its start with the secretion of hormones from the hypothalamus and anterior pituitary gland. These hormones target the sexual organs and begin their maturation. Increasing levels of androgen and estrogen have an effect on the thought processes of adolescents and can be described as them being in the minds "of almost all adolescents a good deal of the time".
