Get the lowdown on your ladyparts with this new book.

You become bashful the second you walk into your gyno's office. If only you could ask what's really on your mind: How many women can't have an orgasm? (Anywhere from 18 to 41 percent.) Why do I eat so much before and during my period? (Hormones make your blood sugar go haywire, spurring hunger.) Can the baby feel us if we have sex while I'm pregnant? (Maybe.)

Dr. Lissa Rankin's new book, What's Up Down There? Questions You'd Only Ask Your Gynecologist If She Was Your Best Friend, goes there and answers every mortifying question about your vajayjay. Rankin covers everything from bodily functions to sex and masturbation to pregnancy in a funny and frank tone that will make you feel like you're gossiping with a girlfriend...who just happens to be a gyno.

We laughed, we cringed, we texted our significant others shocking tidbits. We even shoved it into our friends' hands and proclaimed, "You have to read this!"
