What is a word that is defined by abandonment of sexual roles?

There is no total abandonment of sexual roles, there is abandonment of society declared roles. Even if the role is to be totally equal, there is a role. Transgender is a good Word to use to declare abandonment of society declared roles: it speaks of sex being far more than just bilateral, that there is a changing spectrum of sexual and gender based behavior within specific roles, not black and white. 'Mr Mom' (Michael Keaton) is still a joke, but jokes can be a start. Transgender is about being open to different behavior than is afforded by closed societal roles.
