I think gender is fluid and the binary construct of xx and xy are just a convenience for the sake of conversation.

The spectrum has to run from dyed in the wool/bred in the bone xx or xy to every permutation expression manifestation imaginable. I personally don't believe nurture has much of a role in determining our gender identity.

Dan savage had a great challenge last week (or this?) where he challenged some Canadian politician to prove homosexuality was a choice by choosing to become gay and then sucking Savage's dick.

Makes sense to me.

I think trying to "cultivate" someone's gender is like trying to train someone to not be left handed, or right handed for that matter. The big difference being that "handedness" is not as strong an urge as sexual identity.
