Jon Fortenbury looks at the statistics on virginity:
[M]any individuals who lose their virginities “late” do so for many reasons—not just the stereotypical “can’t get laid” or “super-religious” assumptions. Whether it’s by choice, circumstance, or both, late virginity loss can bring anything from pride to sexual dysfunction for the few Americans who experience it.
According to the Centers for Disease Control and Prevention, the average age Americans lose their virginities (defined here as vaginal sexual intercourse) is 17.1 for both men and women. The CDC also reports that virgins make up 12.3 percent of females and 14.3 percent of males aged 20 to 24. That number drops below 5 percent for both male and female virgins aged 25 to 29 and goes as low as 0.3 percent for virgins aged 40 to 44. …
Statistically, if you didn’t have sex in your teen years, you’re in the minority. But most people I asked in my unscientific poll felt virginity loss wasn’t “late” if the person was still college-aged. Many thought 25 was the first late age. One friend told me that for secular people, “late” is 20 and older, and for religious people, 40 and older. The popular 1999 film American Pie suggests that late is freshman year of college. And the character Jess (played by Zooey Deschanel) on New Girl stated in a flashback in a recent episode, “In three years, I’ll be 25. I can’t rent my first car as a virgin. They’ll know.”
