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

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