No matter where you grew up, learning about the birds and the bees was pretty much the same: It was unexpected, probably involved a book, and necessitated an interaction with your parents that you’d prefer not to revisit.

It also involved a lot of reasons why you shouldn't be having sex. But now you're all grown up, so it's time to rethink some of what you learned.

The good news: Instead of going back to dear old mom and dad, Women’s Health has pulled together a comprehensive list of the mind-boggling benefits of hitting the sheets. From boosting your immune system to releasing aggression, here are the many ways it pays to play dirty.

One of my favorites: Number 9. Protect your pearly whites by stepping up to the mic. Semen contains zinc, calcium, and other minerals proven to fight tooth decay. (Only trace amounts, but who's counting?)

Ok. You can wipe that smirk off your face.
