Final answer:
Developmentally appropriate teaching regarding sexuality should begin during adolescence as young people become more aware of their sexuality. Comprehensive sex education should cover topics such as safer sexual practices, contraception, and preventing STIs. Emphasizing safer sexual practices and contraception is more effective than abstinence-only education.
Step-by-step explanation:
Developmentally appropriate teaching regarding sexuality should begin during adolescence as sexual maturation progresses. At this time, young people become more aware of their sexuality and may become involved in romantic relationships. It is important to provide comprehensive sex education that covers topics such as safer sexual practices, contraception, and preventing sexually transmitted infections. Research suggests that emphasizing safer sexual practices and contraception in sexuality education is more effective than abstinence-only education in reducing unintended pregnancies and the spread of STIs.
