societies. These factors affect girls and boys differently. If girls’ schools and religions are against same sex attractions, they pose the greatest obstacles to girls who experience same sex attractions. These factors were not listed as affecting boys as much. The researchers suggest that maybe this is because not only are some religions against same-sex attraction, but they also encourage traditional roles for women and do not believe that women can carry out these roles as lesbians. Schools may affect girls more than boys because strong emphasis is placed on girls to date boys, and many school activities place high importance on heterosexuality (such as cheerleading). Additionally, the idea of not conforming to typical male gender roles inhibited many boys from openly expressing their same-sex attraction. The worry of conforming to gender roles did not inhibit girls from expressing their same-gender preferences as much, because society is generally more flexible about their gender expression. Researchers such as Lisa Diamond are interested in how some adolescents depart from the socially constructed norms of gender and sexuality. She found that some girls, when faced with the option of choosing "heterosexual", "same-sex attracted" or "bisexual", preferred not to choose a label because their feelings do not fit into any of those categories. Sexually transmitted infections Adolescents have the highest rates of sexually transmitted infections (STIs) when compared to older groups. Sexually active adolescents are more likely to believe that they will not contract a sexually transmitted infection than adults. Adolescents are more likely to have an infected partner and less likely to receive health care when an STI is suspected. They are also less likely to comply with the treatment for an STI. Coinfection is common among adolescents. An STI can have a large negative physiological and psychological effect on an adolescent. The goal of the pediatrician is for early diagnosis and treatment. Early treatment is important for preventing medical complications and infertility. Prevention of STIs should be a priority for all health care providers for adolescents. Diagnosis of an STI begins the evaluation of concomitant STIs and the notification and treatment of sexual partners. Some states in the US require the reporting of STIs to the state's health department. Media influence Modern media contains more sexual messages than was true in the past and the effects on teen sexual behavior remain relatively unknown. Only 9% of the sex scenes on 1,300 of
