In recent years, many young people engage in sexual behaviors. Like the above photo, sexual behaviors place teens at risk for HIV infection, other sexually transmitted diseases (STDs), and unwanted pregnancy. Following the U.S. high school students surveyed in 2015, 30% had sexual intercourse and of these
43% did not use a condom the last time they had sex.
14% did not use any method to prevent pregnancy.
21% had drunk alcohol or used drugs before last sexual intercourse.
Only 10% of sexually experienced students have ever been tested for human immunodeficiency virus (HIV).
CDC data show that lesbian, gay, and bisexual high school students are at substantial risk for serious health outcomes.
