The Xinhua news agency in China quoted a sex expert who claims the Chinese know little about the subject of sex.

In a seminar, Xu Tianming, president of the China Sexology Society, announced, "In the survey we conducted, not only youngsters but many grown-ups are sex idiots, which is really dangerous and woeful."

According to Xu, people could only enjoy a normal sex life until the age of 25, meaning teenagers should be allowed to socialize more freely with members of the opposite sex.

Xu advises, "Parents and society should allow them to have normal contacts with the opposite sex, such as dancing, and to read some books with certain sex descriptions."

Attitudes about sex have relaxed since Communist China began market reforms in the late 1970s, opening the doors to teenage dating and also creating a huge increase in adultery and divorce.
