the report also showed that 81.5 percent of those polled had used a form of birth control. china ranked in the top 3 in this regard.
women were found to be more likely to take precautions, as too were people with a higher educational background.
however, gao said he believed no more than half of china`s youth used condoms or other precautions during first-time sex.
"according to earlier national surveys, only a quarter of those having premarital sex for the first time used a condom," he told china daily.
in recent years, there has been more attention paid to raising people`s awareness of sexually transmitted diseases such as aids, gao said. this has led to the more widespread use of condoms in urban china, but there has been no obvious rise in rural areas.
"many youngsters believe their sex partners won`t have an std," gao said, "and abortion seems easy - you hear commercials for `painless abortions` quite often."
but among china`s high-risk groups, such as sex workers, the use of condoms has increased greatly, gao said.
in another survey on sexual well-being by durex this year, just 42 percent of chinese people said they were completely satisfied with their sex life. the satisfaction rate is lower among women.
according to the report, chinese have sex an average of 122 times a year - higher than the global average.
