After browsing egg_irl I have come to the conclusion that we need a gender change button that makes you the sex and gender you want to be. When we achieve Fully Automated Luxury Gay Space Communism, this will be our first course of action.

Cool moment from TNG: Originally genderless and possessing a very basic humanoid appearance, Lal was allowed to choose a gender and a personal appearance. Deanna Troi reminded Lal that Lal's choice would affect how people interacted with the android. Lal originally wished to share gender and features with Troi, but Data discouraged the move, saying it would be confusing.
