A recent Harris poll found that 51 percent of people think that couples should hold off on sex until marriage, and (somewhat surprisingly) 47 percent of Millennials (ages 18-36) agree. The statistic is unexpected, given the ubiquity of premarital sex depicted in popular culture, but these numbers, which span age, sex, race, education and region, suggest that not everyone gets it on, or thinks you should, before getting hitched.
