Long-standing traditional ideas, such as Zhu's "keeping justice in nature and destroying human desires", have led to prejudice against sex education. [1] Sex education for adolescent students with sexual needs has not been paid attention to. Sexual knowledge is hardly taught in class. At home, parents worry that teaching sexual knowledge will distract their children from studying hard, so they don't spread sexual knowledge. Female students in closed areas don't know what menstruation is and think that kissing will lead to pregnancy. Because they don't understand sexual knowledge and solve their sexual needs through sex, news such as students' pregnancy is common in the media. [3] The survey results in 2003 showed that Chinese mainland college students had a superficial understanding of sexual knowledge, but they had a strong demand for sex. The standards of sexual beauty, sexual aesthetic culture, norms of sexual communication, basic principles of sexual morality, human sexual response cycle, contraceptive principles and methods are all contents that Chinese mainland college students are eager to learn.
