Well there's the fact that they're fighting at that brides door and make the house shake then figure out they can't kill one another so they're like "hey he's my equal" and then *they kiss* So really, hot mansex, not so far a stretch. Seriously Gilgamesh=first gay epic (also first written story recorded thus far in history so beat that!) Also, YAY GILGAMESH normally most people think I'm weird for making references to it since I love it's epic/crazy self so much. The only difference was in our class the teacher kind of pointed out that Gilgamesh and Enkidu sort of had it going on (really one was created to stop the other from terrorizing is lands/the women in his lands before the wedding days)...And then they have epic journeys together with boars and forests and meet Utnapishtim (after *Sad* spoilers) and hear about Noah and the Tree of Life and it's all dandy and the origination of *everything*
...or something like that ^.~
