"Reading is like a sexual act - it happens privately and often in bed," said American historian and author Daniel J. Boorstin.

This book aims to unite sex with reading "in one flesh." It starts with the human body and its sexual function, without omitting the erotic couplings of various animals. It presents the most aphrodisiacal foods, drinks, and desserts, "smells" the corresponding aromas, and presents the naughtiest love tricks and gadgets. It examines the social and historical context, records the labyrinths of erotic desire, lists the famous cases of overachievers in bed, and talks about the rights of "minority" homosexuals, transvestites, and transsexuals. It anthologizes the best readings of the genre, wanders in the kingdom of erotic illustration, observes the evolution of nudity - and of the sexual act in general - in cinema and comics, "listens" to the voices of walls with graffiti around sex, and does not hesitate to even wear a helmet in order to examine sexual propaganda during major wars.

All of this, and much more, can be found in the pages of SEX, with the compass and guide being the words of the great Chilean poet and author Roberto Bolano: "Books are finite, sexual encounters are finite, but the desire to read and make love is infinite."
