The chapter situates sexuality within Gestalt theory as a need for contact and exchange—linked to excitement and pleasure—whose orientation arises from intentionality co-created with the environment. Need and intentionality develop together as field phenomena: we internalize not neutral objects but lived experiences that steer action. Aggression is defined as a bodily motor process—the organism’s movement to take, refuse, or exchange—expressed through respiratory, oral, dental, anal, and genital modalities. Intentionality gives this movement its meaning and yields responsibility for the act. When the original, contact-based intentionality feels dangerous, a “substitute” intentionality emerges; behavior then follows this secondary compass, generating chronic dissatisfaction or refusal and looping unfinished gestalts. By contrast, when aggression serves the original intentionality, behavior is integrated: the person feels present, recognized, and able to accept either fulfillment or a clear “no.” The text clarifies contact boundaries as emergent from meeting intentionalities (illustrated by lions and antelopes maintaining distance) and shows how introjects and interruptions shape defensive forms of aggression. Clinically, the task is to recognize the aggression a person can currently mobilize, re-contact the underlying intentionality, and support more fitting forms of force. A case vignette contrasts collusive sexualization with a response that meets a patient’s primary need for affection, highlighting power asymmetries, accountability, and the importance of naming substitute intentionality to enable adult responsibility.
