Sex has largely been separated from its biological function. For the most part, we engage in sexual activity for intimate communication and sensual pleasure, not reproduction. Conversely, we have devised multiple methods for creating babies without physical sex, albeit most reproduction does still derive from the sex act. This disentanglement of sex from its biological function is not condoned by all sectors of society, but it has been readily, even eagerly, adopted by the mainstream in the developed world.
