Sex education is an eternal topic, because problems related to sex and health have always existed in human society, and have different manifestations and needs in different times and cultures. Sex education aims to provide people with knowledge and skills about sexual behavior, sexual health, sexual relationship, sexual orientation and gender, so as to help them understand and manage sex healthily. This involves personal health, mental health, family relations, disease prevention and other important issues, which is of great significance to teenagers and adults.

In different countries and cultures, the contents and methods of sex education may be different, but on the whole, this is an important topic, because the failure of sex education may lead to many serious problems. Such as termination of early pregnancy, teenage marriage, violence and sexually transmitted diseases. At the same time, sex education is an important democratic agenda, which involves how to give people knowledge and skills so that they can manage their bodies and relationships healthily, rather than being controlled by the government or other official institutions on these issues.

Therefore, sex education is an eternal topic, which is related to human health and happiness, social morality and democratic principles.
