The sex act, in human society, has a plethora of meanings and implications, and, directly or indirectly, generate social structures and norms.

Grace,
I think that this is an intresting problem in itself, actually. Does our ingaging in sex-acts generate (however directly or indirectly) structural norms, or is it the other way around? -I know thats kind of circular, but it makes me think about how Lilith was trying to make sense of things in DAWN. I think that the way the humans eventually began to define themselves atound this mystical act of sex, which they also didnt understand, but sought to understand as something that defined them as human. My first thought right after the attempted rape scene in the book, where one of the guys was like "we HAVE to pair up" was "Wow, what if you were gay? Then what?" and this made me think about how the guys targeted Lilith's guy as a "faggot" and eventually killed him. So given these scenes in the book, was the social structure designed by the act of sex or vice versa? As I read further into your comment I came up with the answer: " The dilemma is so much more than what it means to be a human, its about how we shape our own views without knowing it. if we learned anything from Dawn, its that sexuality changes, it is a dynamic experience."

So I think youre totally set, and do have a focus in your project.
