Sex education should be taught in schools to provide adolescents with formal, age-appropriate instruction about human sexuality, including topics like sexual anatomy, reproduction, birth control, and safe sex practices. While some argue that sex education is a private matter best left to parents, many parents do not discuss these topics and students will seek information from less reliable sources online. Teaching sex education in schools allows students to learn alongside their peers in a structured environment, helping to reduce rates of unintended pregnancy and STIs among teens.
