Sex Education
China has long been considered a conservative country where people try to avoid talking about sex, especially to children. But things have started to change as people attach more importance to sex education. Now an increasing number of schools begin to offer sex education to students.
Sex education, especially at an earlier age, is vital for children's growth. First, sex education provides children with the information they need to understand their bodies and gender roles in positive ways. Second, it boosts the likelihood that teens delay having sex. Third, it helps to prevent unwanted consequences such as premature pregnancy, HIV infection or AIDS.
To launch sex education correctly, parents, schools and the whole society should make joint efforts. At home, instead of telling the children that they were picked up on the street, parents should answer children's questions honestly. In schools, especially high schools, sex education needs to go further, focusing, explicitly if possible, on safe sex. As for the society, it should lift taboo on sex and provide more channels for children to learn about sex.
