Before science put it under the microscope, sex was a simple, uncomplicated thing. You couldn’t build humans without it. All you needed was a man, a woman, a liberal sprinkling of lust and Mother Nature did the rest.

In the future we’ll be able to build humans in tanks, make copies of ourselves in labs and even have the power to change the course of our genetic destiny by turning women into men.
If kissing is nothing more than a way of sniffing out compatible genes, what is the point of sex, and will it ever be the same again?
