(Getty Images) (Newser) – Hong Kongers have a sex problem, reports the AFP: They're apparently not having much of it, and one theory as to why may surprise you. Real estate prices. That's right, "One of the reasons is they have no place to have sex," explains a professor who helps head up the University of Hong Kong's Family Institute. "Hong Kong is too crowded and lacks the privacy people need to have sex," he explains, adding that astronomical property prices force many residents under 40 to bunk at home, within earshot of their parents. The reality has sex experts pushing residents to do it more often, in a bid to change their reputation for having the "least amount of sexual knowledge in the world" and potentially up their bottom-of-the-barrel birth rate of 1.04 births per woman.
