In the future men have become obsolete. It's a matriarchy. Cities are split into men and women sides. Women's part of city is more modern, cleaner, safer. Men's side is full of gangs, violence, trash. All women agree that the only thing men are good for is for sex and giving them babies. Most women hate men but enjoy sex with them. So that's what a majority of men are trained for. To give women maximum pleasure and give them a healthy, strong baby. You are one of the men trained to do this.
