We Love Intercourse

95% of Americans have had premarital sex. The study was done with mostly women though, so all the loser dudes out there who can't get a date would probably bring the average down.
99 percent of respondents had had sex by age 44 and even those who abstained until at least age 20, 80% had had premarital sex by 44.
Among women born between 1950 and 1978 (before girls became sluts), at least 91 percent had had premarital sex by age 30.
