Asia in Durex Sex Survey

According to Durex Sexual Wellbeing Global Survey 2008, which polled 26,000 people in 26 countries: less than a quarter -- 24 percent -- of those surveyed from China and Hong Kong were able to achieve an orgasm every time they had sex.

Other Asian countries such as Japan and Singapore ranked poorly with those polled saying they only reached orgasm 27 percent and 36 percent of the time respectively.

Of those who manage to climax, the Japanese were the least satisfied with the intensity of the orgasm.

Over all, women climaxed less than men, with 32 percent saying they reached the peak every time they had sex, compared with 63 percent of men.

Factors that enhanced an orgasm included delaying climax, longer foreplay time and having a strong emotional relationship, the survey said.
