Everything You Ever Wanted To Know About The Penis

February 7, 2016 by Justin Lehmiller


Penile appearance varies widely throughout the animal kingdom. For instance, some penises have multiple heads (spiny anteaters), others are shaped like a corkscrew (lake ducks), and yet others are several times the length of the creature’s entire body (barnacles). Upon hearing about such incredible penile diversity, you might be tempted to conclude that the human penis is rather boring by comparison—but you’d be wrong. The human penis is still a pretty fascinating piece of anatomy in its own right.

In a recent documentary entitled (appropriately enough) “The Dickumentary,” filmmakers interviewed more than 40 penis experts from around the world with the goal of compiling the most comprehensive scientific look at the penis to date. The film addresses everything you ever wanted to know—and then some. Not only does it trace the evolution of the penis over time, but it also takes on some of the “biggest” questions people have about the penis, such as “does size really matter?” The film also explore cultural variations in how the penis is viewed, including a look at Japanese penis festivals.

You can check out a brief snippet of the film below. To check out the full version, you can rent or buy it through Amazon by clicking here, or get it through iTunes by clicking here. Enjoy!
