Even Grandma had premarital sex, survey finds

More than nine out of 10 Americans, men and women alike, have had premarital sex, according to a new study. The high rates extend even to women born in the 1940s, challenging perceptions that people were more chaste in the past.

“This is reality-check research,” said the study’s author, Lawrence Finer. “Premarital sex is normal behavior for the vast majority of Americans, and has been for decades.”

Finer is a research director at the Guttmacher Institute, a private New York-based think tank that studies sexual and reproductive issues and which disagrees with government-funded programs that rely primarily on abstinence-only teachings. The study, released Tuesday, appears in the new issue of Public Health Reports.
