Yep, it's important. (Shock.) Two of the major game-changing events in The Epic of Gilgamesh involve sex, or the refusal of it. (1) Shamhat uses sex as a way to civilize Enkidu. In Mesopotamian culture, sex with a gal like Shamhat connected her lover to the divine life-force, so to speak. This apparently explains how Enkidu becomes more man than beast (which, when you think about it, is a funny inversion of how we usually think about sex—that it makes us like animals). And then (2) Gilgamesh rejects the sexual advances of the goddess Ishtar. Big mistake. If Gilgamesh had gotten busy with Ishtar, this story may have had a very different outcome. So, the take-home point seems to be careful who you do it with. And that's a message we think everyone can get behind
Sex with Shamhat removes Enkidu from the animal world because it builds a close connection between him and another human being.
The Epic of Gilgamesh portrays women primarily as sex objects, or as characters whose most important activities involve sex.
