Gay Males: Why wouldn't you react to this situation?

Ok so Im a straight guy and when I walk around I love to look at chicks and I think "nature is cool" cuz of how hot they are to me. Anyways, this made me think about gays in nature. So let's say you didn't have influences like Brokeback Mountain, other gays in school, the media and all the stuff in modern society. Let's say you were born in the jungle and didn't know about being gay, then you're walking and come upon a waterfall with like 6 naked chicks in the water and their bodies showin (like they're standin up with their legs in the water) Would you seriously not react and not think they were real hot and want to run in there and do some stuff with them? come on, be honest
