While human beings often have sex for pleasure, the instincts that drive human mating behavior have been shaped by a deadly serious game of evolutionary selection. Sexually attractive people are those whose characteristics suggest they are well equipped to help you propagate your genetic line successfully. Even a single good feature can make you attractive enough to be a sexual success. Women have this relatively easy.
