desire is determined by testosterone level (yes women have testosterone in their body, just not nearly as much as men). when you are stressed out or exhausted, stress suppresses the testosterone in your body and women don't have a lot of testosterone to start with; therefore, desire is also diminished... and that's why you don't see men's desire reduced nearly as much when they are stressed out
