and impact human behavior. At the start of this foundational work, Ellis reveals his long-standing commitment to studying sexual psychology, rooted in his own youthful inquiries into the subject. He lays the groundwork for his discussions by defining modesty as a key emotion that influences sexual behavior, particularly highlighting its importance for women. He contrasts historical views on sex with modern observations and emphasizes the need for a scientific approach to understand sexuality free from moralistic agendas. Ellis argues that both men and women possess a complex relationship with their sexual identities shaped by societal expectations, and he implores readers to approach the subject of sex with sincerity and openness to foster a deeper understanding of its role in human life.
