In Margaret Atwood's "Oryx and Crake," the quote compares sex to drinking, suggesting that contemplating such desires too early can lead to regrettable choices. This analogy highlights the idea that indulging in certain thoughts or cravings prematurely can complicate one's life, much like starting to drink before the appropriate time. It implies the need for moderation and timing in both relationships and personal habits.

Atwood's work often explores complex themes surrounding human nature and societal issues. By using this analogy, she prompts readers to reflect on the impact of their desires and the importance of self-control. Ultimately, the quote serves as a reminder that some things are best savored, rather than rushed into, reinforcing the necessity of balance in our lives.
