Teaching sex education to teenagers requires a sensitive and comprehensive approach. Start by creating a safe and open environment where teens feel comfortable asking questions. Cover topics like anatomy, puberty, reproduction, contraception, STIs, consent, and healthy relationships. Use age-appropriate language and materials. Encourage critical thinking and decision-making skills. Address myths and misconceptions. Involve parents or guardians when appropriate. Remember to be respectful, non-judgmental, and evidence-based in your teachings.
