Here's What a Penis Bone Looks Like

While human men you know do not have calcified bones they can bone with, apparently a lot of other mammals do, Forbes reports.

The penis bone is called a baculum and according to a new review by Nicholas Schultz of the University of Southern California, other mammals use it to keep their penises erect longer without requiring the change in blood pressure humans need to keep their boners up.

Apparently, decades of research still hasn't lead scientists to fully understand this penis bone, but if it's seemingly just used to keep boners boning for longer, that may be all we need to know.
