I have reference. For the U.S. www.cdc.gov/nchs/products/databriefs/db366.htm Data from 2015 2017. In 2015–2017, 42% of never-married female teenagers aged 15–19 and 38% of never-married male teenagers had had sexual intercourse; the percentage declined by 17% for male teenagers between 2002 and 2015–2017. And some newer data. www.cdc.gov/yrbs/dstr/index.html This site here uses that data and made easy to read graphs. opa.hhs.gov/…/data-and-statistics-on-adolescent-s… Like this one. Showing most kids graduate high school without having had intercourse yet. Another gov site with data for 2024. stacks.cdc.gov/view/cdc/134957
