The number one way (more effective than medication) to increase a woman's libido is an extra hour of sleep. It's truly no wonder that getting negative hours of sleep for a literal year at least kills libido.

I'm pregnant and the insomnia is killing me. 4 or 5 hours a night, usually. And the poor sleep will only continue when the child is born. Everyone's talking about how men need to help more with chores and all that's true and good that you need division of labor, but even if you're good at division, the sleep loss with children is inevitable.
