I expected a high percentage of people to lose their virginity during their teenage years, but I didn’t expect it to rise that quickly. Maybe I was sheltered.

The cumulative percentages are based on survey results from the 2013-2015 National Survey for Family Growth. There have been two more data releases since, but more data is obscured each year to non-researchers. While I suspect some change, I’d bet it’s not that much.
