In his book, Dr. Sameh Marcos adheres only to the information that science has reached through experience and testing, believing that love and sex are blessings that bring happiness and legitimate pleasure to humans. These blessings are repressed by some societies under the pretext of impurity of the body compared to the sanctity of the soul, or asceticism in worldly pleasures. This leads to psychological problems for the individual and societal repression, which generates violence, oppression, and discrimination. The book covers a number of topics, such as the history of sexology, identity, sexual practices, and diseases. However, what is striking is the researcher's interest in observing how the ancients dealt with this topic. There is a chapter on love and sex among the ancient Egyptians, with references in many chapters to love and sex among the Greeks and Romans, Islamic history, and medieval Europe. We find that we have come to prohibit what our ancestors understood and permitted. With a chapter on how art has addressed love and sex, particularly visual art throughout the ages, and references to how writers and thinkers have addressed them, this book is expected to change your perspective on many of the unspoken and forbidden matters we take for granted, and to correct much of the information that, unfortunately, some people obtain through popular myths or pornographic websites. Science comes to clarify and explain; for the sake of the health, advancement, and happiness of man; the creature distinguished by his mind, knowledge, and art.
