The quote from Iain M. Banks' "Excession" reflects the idea that engaging in promiscuity is not merely depleting a limited resource, but rather consuming a continual desire that hinders one's personal development. Instead of seeing relationships as fleeting moments, the character realizes that this fixation can stifle their ability to grow and evolve over time.

This notion suggests that indulgence in superficial connections can have a long-lasting impact on an individual's potential. It serves as a warning about how certain choices may lead to a cycle that ultimately prevents meaningful progress in life and self-improvement.
