6. Yes, Penises Can Be Broken
I realize it's every man's worst nightmare, but it's true. While it might not be at the top of the sex-related injuries (the top spots go to bruises and rug burns), penises can be fractured during vigorous intercourse. Surprisingly, missionary is the most "dangerous" position for a man to break a penis, followed by cowgirl, and reverse cowgirl, to round out the top three.
