Pornhub had its annual sex survey, and it just published this interactive map showing how much time people spend having sex on average. North Americans, for example, spend 9 to 11 minutes while Chinese last, on average from 13 to 15 minutes. Or at least that’s what they claim.
North Korea doesn’t have internet, but their average is probably two hours and 59 minutes, because Kim Jong-un can have sex for 19 days in a row, and that skews the entire country’s average.
