          Report: First sex taking place sooner

          By Yang Wanli | China Daily | Updated: 2016-01-12 08:12

          China's younger generation is tasting the "forbidden fruit" of sexual intercourse at earlier ages compared with their predecessors, according to a report by Peking University's Center for Social Surveys that was released on Sunday.

          People younger than 20 had their first sex with a person of the opposite sex at age 17 on average, the report said.

          For those 35 or older, the average age for first sex was 22.
