In the late 19th and early 20th centuries, Austrian Sigmund Freud, a physiologist and psychiatrist, laid the foundations of psychoanalysis as a therapeutic method with his studies and revolutionized the way modern man perceives concepts such as consciousness and sexuality.

Sexual morality and modern nervousness is Freud's study on the impact of culture on human sexual morality. To what extent does this cultural sexual morality justify the sacrifices it imposes on us? How can the extensive rules of culture lead to perverse impulses and nervousness? Under the microscope of analysis is the life of the couple and how it can lead to sexual happiness or the neurosis that undermines happiness and life itself.
