"The Junkyard" by Rob Kutner (contains adult robotic content)
In the future, you can change your parts as easily as you change your pants.

Men become women, and women become men - often, due to a long bathroom line. Women organize and triumph in World Snow-Pissing Contests; men spend whole months going to 3rd Base with themselves.

Blurring gender lines make business-world sexism and homophobia unsustainable, verging on hilarious. Dual-installment capability makes masturbation a thing of the past, and unplanned self-pregnancy the crisis du jour.
Meanwhile, the planet starves, chokes, and bakes to death - while all 9 billion of us 2-year-olds sit in the bathtub and play with our wee-wees.
