Starting at an earlier time increases the chance of healthy lifestyle choices becoming a lifestyle and allows students to become accustomed to healthy sexual lifestyles. Sex education courses provide knowledge about various sexually transmitted diseases and how they are transmitted, safe sex, different contraceptives and the consequences of choosing not to practice safe sex. Providing adolescence with this type of knowledge would reduce rates of sexually transmitted diseases. For example, many teens don't know that STDs can be transmitted during oral sex or don't know that they can get pregnant the first time they have sex. Awareness of the different contraceptives offered would help reduce the rate of unwanted pregnancies among adolescents. Most teenagers drop out of high school to work or to stay home and care for their children. Changing the trend of unwanted teen pregnancies would result in more high school graduates, which would lay the foundation for responsible and successful adults. The higher an individual's level of education, the more opportunities they will be presented with. Your high school diploma is the platform you build on to become a successful individual. Sex education lessons explain the importance of abstinence at a young age, which could be introduced in adolescence before they take part in sexual activity.
