In rural areas, due to the influx of migrant workers into cities and industrial and mining enterprises, most of their children have become left-behind children, cared for by the elderly and relatives and friends, and have a weak concept of sex education. Teenagers are in adolescence, their sexual psychology is not correctly formed, and their outlook on life and values are not correctly established. They are in a state of youth and ignorance. With the maturity of physiology, their sexual psychology gradually appears, and the phenomenon of ignorance, obscurity and curiosity becomes more and more prominent.

Therefore, sex education in rural primary and secondary schools is imperative in order to make up for the gaps or deficiencies in family sex education. At present, the country attaches great importance to basic education, with huge investment in education, strong teachers in rural primary and secondary schools, reasonable teacher structure and high quality teachers. They will not only carry out sex education in schools, but also take the forms of flexibility, eclecticism, combination of biology teaching, combination of teaching related knowledge points, combination of ideological and moral education, combination of individuals and groups, and emergency education.

To correctly guide sex education and sexual hygiene, teachers should get rid of the interference and influence of customs, narrowness and feudal superstitions, be people-oriented, care for students, be a teacher by example, cherish morality and set an example by virtue. Let students learn relevant knowledge, understand sexual physiology, develop correct sexual psychology, understand the relationship between family and marriage, marriage and sexual physiology, learn sexual hygiene knowledge and daily practical skills, promote students' sexual physiology and mental health, and thus establish students' correct outlook on life and values. In this way, teenagers can thrive in adolescence, become high-quality people and be useful to society.

Carrying out such sex education in rural primary and secondary schools conforms to the national conditions and people's feelings, the requirements of the development of the times and the objective needs of social development and progress. As an education department, there should be no slack and paralysis. Sex education for teenagers should be long-term, fixed and practical, and implemented in daily education and teaching.

With the concept of "a century-long plan, education comes first", I believe that sex education for teenagers in rural primary and secondary schools will be better and better, parents will be more and more assured and the society will be more and more satisfied. Sex education for teenagers in rural primary and secondary schools has only advantages, advantages and disadvantages, and it is a great educational project.
