If there's one thing China knows, it's what women are doing wrong: nagging your husband will discourage sexual intercourse. The study by "Chinese University" says 81 percent of women who were regularly negative towards their husband had not had sex in the past year, and overall a third hadn't slept with their husband. In the past year. That's a long time; guys reported only five percent sexless for a year, so apparently 25% of women had sex with their husbands but didn't know it. Certainly, all sorts of other possibilities are listed in the article - and women have their own batch of excuses - but those reasons men gave for avoiding sex are all lies - China is certain their country's male sexual dysfunction is not from overwork, poverty, joblessness, disease, or stress, but simply because their wives are too critical. It was so obvious!
