Ok I’m just gonna say this, I know it sounds kinda stupid, but a gender switching machine, easy, just step into the machine and it switches your gender and gets the hormones of your old gender out of your body, and replaces them with the hormones of the new gender, and it even changes your legal gender and name too. Like I said it’s kinda stupid, I have a mind full of “bright ideas” that could possibly end the world.
