Libido can ebb and flow for all sorts of reasons.
First, I want to remind you that there's no such thing as a normal sex drive. Take the stats out there about how often other people typically have sex with a grain of salt; it varies for everyone (and, hey, people lie!). Female sex drive is nuanced, and your libido rises and falls naturally.
For example, you might have a higher sex drive around the time of ovulation (the bodys way of telling you to get frisky during your fertile time, even if youre not actively trying to become pregnant). Or, you may not feel like being sexually active during other times of the month, like when you're on your period (though if youre into period sex , it can be enjoyable too).
