When Americans First Learned About Sex, According To A Survey

Andrew Zaeh for Bustle

I was probably about 12 when I first learned about sex — well, kind of. The boy across the street from me informed my sister and I that sex was when a man put his penis in a woman and "shook it all around." When I shared this information with my mother, she cleared up a few things... but not really. And people wonder why there's such a need for comprehensive, inclusive sex education, sex positivity, and to close the orgasm gap.

According to a recent survey of 500 Americans and 500 Europeans aged 18 to 76, by online doctor, Zavamed, I was actually little on the older side when I first found out about sex. In the United States, most girls first learn about sex at age 10, while for boys it's 11 years old. In Europe, kids are even older, with girls first learning about it at 12 and boys first learning about it at 13.

But, of course, learning about sex for the very first time is just the beginning. Here are the average ages most people in Europe and the United States are when they experience other sex-related firsts, from masturbation to reaching third base, according to the survey.
