People have been getting freaky in the bedroom (and outdoors) for centuries, and sometimes, things get pretty crazy. Whether it's because of tradition, culture or just general kinkiness, there's a bunch of weird sexual customs the world over that make you go WTF.

5. Girls of the Trobriander Tribe engage in sexual acts from age 6

The Trobriander Tribe from Papua, New Guinea embrace sexuality from an astonishingly young age. Boys start engaging in sexual activity from the age of 10-12, while the girls start from 6 years! Isn't that illegal?

6. In Ancient Greece, men took young boys as lovers
