I'd just like to interject for a moment. What you're referring to as sex, is in fact, gender/sex, or as I've recently taken to calling it, gender plus sex. Sex is not a discrete biological trait unto itself, but rather another component of a fully functioning gender system in which aspects of social roles, personal identity, and yes, metabolism and anatomy have been discursively constructed as "sexed".
