**Libidinal satisfaction**, according to Fairbairn, is not a primary drive but rather a secondary need that arises from the individual's relationship with their primary caregivers. It involves the seeking of pleasure and gratification from relationships and interactions with others, rather than being an innate biological urge. Fairbairn believed that libidinal satisfaction is crucial for emotional and psychological well-being, and its fulfillment is essential for healthy development and functioning.
