This chapter reframes sexuality and aggression as twin instincts whose healthy balance underpins human development and relationships. Building on Gestalt’s figure–ground principle, it argues that when sexuality unfolds in a field where (especially “dental”) aggression is acknowledged and integrated, fusion and dependency are limited, autonomy grows, and contact becomes more creative. Sexuality is defined by arousal, sensual pleasure, and exchange; arousal makes boundaries more permeable and drives movement toward the other, while pleasure amplifies mutual responsiveness in a positive feedback loop. The authors contrast love (care that stabilizes bonds) and power (an acquired source of pleasure that can distort exchange), showing how sexuality without care slides toward appropriation and destructiveness, and care without pleasure stagnates into duty and dominance. They trace the cultural control of sexuality—its role in pair-bonding, social organization, and moral regulation—and discuss clinical questions that invite responsibility: “What are you doing with your aggression?” and “What are you doing with your sexuality?” Finally, they highlight sexuality’s expansive functions beyond reproduction—health, creativity, social cohesion—and preview how contemporary culture co-shapes sexual experience, calling for a field-based ethics of choice, awareness, and shared responsibility.
