A peek into women's bedrooms in 2016

Want to improve your sex life? There's an app for that.

In fact, 500,000 women turned to one such app, Eve, to share sex advice and track their feminine health cycles, says the company that makes the app, Glow. (Glow is a startup created by PayPal mafia member Max Levchin.)

Thanks to the volume of women using the app, Glow was able to look back at data throughout to get a peek into women's bedroom lives in 2016.
