A world to define ones 'gender' not sex.
Boys do not need to have a penis, and boys do not always play sports either. Boys can be
feminine, boys can be
masculine. If they call themselves a boy, they're a boy, no
questions asked.
"Hey, did you hear about Sarah? She won that
super cool trophy
yesterday!"
"Oh, you mean Ethan? Ye he totally deserved it."
"He? She's a she?"
"No, respect his pronouns, he's a boy. What's in his pants
doesn't matter."
