The document discusses the core of sex and its evolution. It begins by stating that attraction between males and females is universal and has existed throughout history. For animals, sexual attraction revolves around reproduction and rearing offspring. In humans, sexual attraction becomes more evolved and associated with romance and commitment. At the core of sex, one finds the core of the other individual, which is a difficult but worthwhile goal of transcending physical considerations and culminating in a super-romance for global welfare, according to the author.
