According to a survey by condom maker Durex on sexual habits of people around the globe, Hong Kong locals are, for the fourth year in a row, having much less sex than the global average.
Hong Kong people engage in sex 78 times a year, well behind those on the mainland and miles away from the lusty Greeks who are amorous on 138 occasions. The global average is 103, the survey said.
Coupled with a lack of a quality education on the matter and prevailing social values that encourage restraint, many in Hong Kong wind up with troubled sex lives. And it is a situation that has some local experts worried.
