Chinanews, Beijing, July 26 – In 2006, one-fourth of Chinese adults had sex experience with more than one person, according to Professor Pan Suiming, who was also director of the Institute for Research on Sexuality and Gender under the Renmin University of China. The findings are included in the professor's most recent survey that was released on July 3.Some people applaud the survey result thinking that China has made great achievement in sex revolution. Other people, however, express their worry about the result, saying that Chinese social morality has deteriorated.Three days later, on July 6, in an interview given to Life Times, Professor Pan further declared that “the sex revolution has basically proved to be a success in China.” As the professor said, more and more Chinese people now have more than one sex partners, which shows to some extent that Chinese people hold a more liberal view towards the sex issue.The survey, titled "Chinese People's Sexual Behaviors and Sexual Relations Development in 2000-2006", was conducted by the professor after he and his team had investigated 6,010 people between the age of 18 and 61. The survey covered topics like premarital affairs and homosexuals. The most notable point about the survey is the finding that Chinese people have more than one sex partners.In 2000, about 16.8% of Chinese had more than one sex partners. By 2006, however, the percentage had risen to 25.3, with an annual growth rate of 7%. During the 1980s, however, the percentage was only 6, according to the findings by Professor Liu Dalin, founder of China's first sex culture museum.
