Adolescent sex education is sexual health education for teenagers aged 1 1~ 18. This is the key stage of the whole sex education. It is mainly to impart scientific sexual knowledge to teenagers, correct cognitive and behavioral deviations related to sex, and establish a healthy sexual consciousness. On the basis of sexual physiology and psychological education, we should focus on quality education in sexual ethics, legal system, emotion, aesthetics and personality. Professor Wu Jieping has an incisive exposition on this: "Adolescent education is aimed at the physiological and psychological characteristics of adolescents entering adolescence. Generally speaking, it is a comprehensive education in personality education, life education, ideological and moral education, patriotism education, law-abiding education, sexual knowledge and sexual morality education. " "Sexual knowledge education can guide teenagers to maintain their sexual and physical health; And sexual moral education can help teenagers build noble sentiments in the process of successfully completing the transition of adolescence; The education of self-esteem, self-respect and self-love in sexual concept is beneficial to the sound development of teenagers' personality. "The rise and rapid development of adolescent sex education is the inevitable result of the development of modern education, but its establishment has a tortuous process of endless debate. The argument is mainly manifested in three aspects: first, self-learning without teachers and the need for teachers to teach. People who hold the view of "self-learning without a teacher" think that when children grow up, they will naturally know what is going on between men and women, and there is no need to wake them up. People who hold the view that "we must be taught by teachers" believe that "type" is one of the most basic biological characteristics of human beings. Human sexuality is different from animals. It is not only a physical combination between the two sexes, but also has human characteristics to show humanization, civilization and socialization. In order to adapt the code of conduct for men and women to social needs and moral requirements, sex education must be carried out to cultivate correct sexual concepts. Second, closed protection and adaptation education. People who hold the view of "closed protection" believe that sexual knowledge should not be taught to teenagers by language, and the flexibility of teenagers is moral purity. People who hold the view of "conformity education" believe that youth development is the only way in life, and sexual maturity will naturally produce the desire for sexual knowledge and the yearning for the opposite sex. Third, induction and guidance. People who hold the view of "inducement" believe that sex education will cause sexual stimulation, while sexual knowledge teaching will play a role in inducing promiscuity. It's not too late to re-educate if there are problems. People who hold the view of "guidance" believe that adolescent sexual deviance is by no means induced by correct education. On the contrary, it is precisely because they did not get the correct guidance and education that they went astray. Sex education and sexual stimulation are not difficult to distinguish, and the content of sex education and pornography are completely opposite. Pornographic and obscene content deliberately arouses sexual desire, makes people too excited to control themselves because of strong sexual excitement, and induces teenagers to lose their minds and fall into sexual crimes. The content of sex education is to tell teenagers the scientific knowledge they must master with an objective attitude, so that they can rationally understand how to treat their own sexual problems. If problems are found, education and correction will be very difficult, and it will take many times of efforts to restore the damaged physical and mental health.
