Adolescent sexuality is a stage of human development in which adolescents experience and explore sexual feelings. Interest in sexuality intensifies during the onset of puberty, and sexuality is often a vital aspect of teenagers' lives. Sexual interest may be expressed in a number of ways, such as flirting, kissing, masturbation, or having sex with a partner. Sexual interest among adolescents, as among adults, can vary greatly, and is influenced by cultural norms and mores, sex education, as well as comprehensive sexuality education provided, sexual orientation, and social controls such as age-of-consent laws.
Sexual activity in general is associated with various risks and this is heightened by the unfamiliar excitement of sexual arousal, the attention connected to being sexually attractive, and the new level of physical intimacy and psychological vulnerability created by sexual encounters. The risks of sexual intercourse include unwanted pregnancy and contracting a sexually transmitted infection such as HIV/AIDS, which can be reduced with availability and use of a condom or adopting other safe sex practices. Contraceptives specifically reduce the chance of teenage pregnancy.
The risks are higher 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 that are deemed important for self-control, delayed gratification, risk analysis, and appreciation are not fully mature. The prefrontal cortex area of the human brain is not fully developed until the early 20s or about 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 being causative.
Development of sexuality
Adolescent sexuality begins at puberty. The sexual maturation process produces sexual interest and stimulates thought processes. Subsequent sexual behavior starts 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 have been described as being in the minds "of almost all adolescents a good deal of the time".
Though most female adolescents begin their sexual maturation process in normal, predictable ways, there may be concerns by parents and clinicians if the following become evident: painful menstruation chronic pelvic pain partial vaginal outflow obstruction/imperforate hymen possible anatomical defects
Views on sexual activity
One study from 1996 documented the interviews of a sample of junior high school students in the United States. The girls were less likely to state that they ever had sex than adolescent boys. Among boys and girls who had experienced sexual intercourse, the proportion of girls and boys who had recently had sex and were regularly sexually active was the same. Those conducting the study speculated that fewer girls say they have ever had sex because girls viewed teenage parenthood as more of a problem than boys. Girls were thought to be more restricted in their sexual attitudes; they were more likely than boys to believe that they would be able to control their sexual urges. Girls had a more negative association in how being sexually active could affect their future goals. In general, girls said they felt less pressure from peers to begin having sex, while boys reported feeling more pressure.
A later study questioned the attitudes of adolescents. When asked about abstinence, many girls reported they felt conflicted. They were trying to balance maintaining a good reputation with trying to maintain a romantic relationship and wanting to behave in adult-like ways. Boys viewed having sex as social capital. Many boys believed that their male peers who were abstinent would not as easily climb the social ladder as sexually active boys. Some boys said that for them, the risks that may come from having sex were not as bad as the social risks that could come from remaining abstinent.
Concepts about loss of virginity
In the United States, federally mandated programs started in 1980 and promoted adolescent abstinence from sexual intercourse, which resulted in teens turning to oral sex, which about a third of teens considered a form of abstinence in a study.
