(NEW YORK, NY) -- It turns out that Venezuelans, who topped a survey last year as the vainest people in the world, are also happiest by far about their sex lives.

A Roper Starch Worldwide survey released Thursday found that 46 percent of Venezuelans were ``very happy'' with their sex lives followed by Brazilians at 32 percent and U.S. residents at 27 percent.

People in Hong Kong, which was surveyed separately from the rest of China, were the least satisfied with their sex lives -- only five percent said they were ``very happy.'' Russia followed at six percent, then China at nine percent and Germany, Italy and Malaysia all tied at 14 percent.
