If you’re well-schooled in sexual health, you probably know that you should wear a condom to protect yourself against pregnancy and STDs. You probably also know how to put one on and take it off (doing it right is the best way to ensure it works!). But did you know that U.S. soldiers used condoms to protect their weapons from dirt and water in World War II? Or that that there’s a quaint little town in France called condom? And just try to guess how big the world’s biggest condom was.
