As China people, who have always regarded implication as their virtue, our traditional sexual culture is conservative and secretive. It seems that some people feel embarrassed and uncomfortable when talking about sex. However, we are inseparable from sex from birth. How can we not have sex? So, why talk about transsexuality? On the other hand, with the development of economic globalization, western sexual culture and concepts have a great influence on China, especially some concepts of "sexual liberation" and "sexual freedom". Of course, the western sex culture is not all-inclusive, and there are many aspects worth learning from. For example, sexual physiology, sexual psychology, knowledge of sexually transmitted diseases and open education on their prevention and treatment.

Sexual health education in China started late, and under the impact of globalization, there are more and more deficiencies. Therefore, "personality-based marriage and family education", that is, education with both sexual knowledge and sexual morality, is very necessary.

In different periods of life development, people will face different sexual psychological problems. Under the action of sex hormones, with the rapid development of sexual physiology, college students have strong sexual desire and instinctive sexual impulse. At the same time, their sexual psychology has also developed, resulting in a strong sense of sex. They have active sexual feelings and thinking, which makes them extremely sensitive and curious about sexual issues.

At the same time, influenced by western sexual concepts, college students' sexual morality is weakened, and most of them are tolerant of premarital sex. They think that college students can have premarital sex, and some students even think that unmarried cohabitation is a way of modern social life.

At present, premarital sexual behavior of college students is not common, but this change in sexual morality is likely to lead to a sharp rise in premarital sexual behavior of college students in the future. Therefore, the most effective means of guidance is moral education. Strengthening the education of college students' views on love, love, family mate selection and life will promote the formation of their healthy personality, and at the same time help to establish good interpersonal relationships and prepare for future love, marriage and family. Therefore, ideological and political educators in colleges and universities should get rid of old ideas, change passivity into initiative, carry out necessary sexual health education, pay attention to strengthening the guidance and sexual awareness education of college students, make efforts to correct the prejudice of college students' sexual concepts, help them understand sexual problems comprehensively, scientifically and correctly, and cultivate their positive and healthy sexual concepts.

The sociality of people determines that people should not only be responsible for themselves, but also bear certain responsibilities, including moral responsibilities, to the nation, country, family, relatives and friends, and others. College students are the main reserve force in the current national construction, and the cultivation of college students' sense of responsibility will affect the construction and development of the whole country. Sexual moral education can enhance college students' sense of social responsibility. It is believed that the core of college students' sexual moral education is responsibility, which combines sex with responsibility according to its social attributes. Let college students understand that sex is not only a personal problem, but also a social problem. Although college students' premarital sex or extramarital sex is relatively secret in the implementation process, some bad results are problems that society will face. Such as abortion, illegitimate children, AIDS and so on, are mostly caused by irresponsible sexual behavior, which is not only a problem between the parties, but also a problem that affects the whole human society. The lack of sexual responsibility will cause social chaos and some people's suffering. As a reserve talent for social construction, sexual health education for college students is conducive to the stable development of society.

Sex is accompanied by a person's life, and he also has a process of growth, development, maturity and decline. With the change of sexual physiology, people's sexual psychology has different reactions in different periods. In a person's life, sex is an important factor affecting physical and mental health, and sex health education is an inherent requirement for the healthy development of people's body and mind. College students are in the late adolescence, and their sexual psychology and physiology tend to be mature. They are eager to understand sex and communicate with the opposite sex. Timely sexual moral education for college students in this period can help them correctly understand and face their own physiological and psychological changes; Can guide college students to deal with the communication with the opposite sex; It can guide college students to form a positive view of marriage and love, learn to respect the body and life, and is conducive to the healthy development of college students' individual body and mind.

Since people can't live without sex, why don't we face it seriously? Only by knowing it, understanding it and reading it can we better face it and deal with it. True love is the meeting of souls. Only when you meet someone who can trust you for a lifetime will you have a happy family and perfect sex. Therefore, it is very necessary to carry out sexual health education among college students, which can not only make up for their lack of sexual knowledge, but also help them establish correct sexual morality and create a better atmosphere of love for our society.
