10 Eye-Opening Facts You Actually Didn’t Know About Vaginas, Sex, Orgasms, and More
Now this is our kind of sex ed.
When it comes to sexual health, we’d like to think we’ve covered it all—from male and female anatomy to sex, orgasms, and fertility. And we’ve definitely delved into our fair share of questionable vagina trends, such as whether inserting garlic into the vagina can treat a yeast infection and if squatting over steaming coffee really will induce labor. (No and no, for the record.)
So when we came across The Wonder Down Under ($21, amazon.com), we were surprised to learn that there’s actually a lot more we haven’t covered concerning sex and sexual health. In fact, we learned so much from coauthors and sex educators Nina Brochmann, MD, and Ellen Stokken Dahl, we knew we had to share. Below, 10 fascinating tidbits you probably didn’t know about your wonder down under.
There’s more to the clitoris than meets the eye
Most people think that the clitoris is a small pleasure zone tucked inside the vulva. Turns out that what you see is only the tip of the iceberg, so to speak. The clitoris extends well into the pelvis—and it develops from the same tissue as the penis.
“Up until about the twelfth week in the uterus, the genital tracts of male and female embryos are exactly alike, dominated by a kind of mini-penis (or giga-clitoris!) known as the genital tubercle,” write Brochmann and Stokken Dahl. “It has the potential to develop into either a female or male sexual organ. Since the penis and clitoris both develop from the same basic structure, the two organs share many similarities of form and function.”
One difference: The head of the clitoris has 50 times the concentration of nerve endings as does the head of a penis. No wonder even a little too much pressure there can quickly go from pleasurable to painful.
Pubic hair can boost your sexual pleasure
Going bare down there might make you feel sexier. But keeping some pubic hair comes with a surprising benefit: more pleasure during sex. Hair around the vagina helps “to heighten our sexual sensitivity,” the authors state. “If your partner strokes you lightly over your pubic hair, the bending of the hairs will send a signal to the follicles, which will pass the message on to your nervous system.” Without bush, you might be cheating yourself out of sexual sensation.
If you are shaving down below, cheaper razors are better
Yep, you read that right. Apparently single-blade razors are better. Why? Pricier ones that come with multiple blades are more likely to cause ingrown hairs, since each additional blade cuts hair farther beneath the surface of the skin. “What’s more, the high price means that a lot of people avoid changing blades as often as they should, so that the blades become blunt and covered in bacteria,” according to Brochmann and Stokken Dahl.
Discharge keeps things clean
“The purpose of discharge is to keep the vagina clean and to flush out unwelcome guests such as fungi and bacteria, as well as dead cells from the surface of the mucous membrane,” write the authors. This whitish or clear fluid (depending on where you are in your cycle) also contains a decent amount of good bacteria, like lactobacilli, to help ward off infections.
That’s not all though. Discharge helps lubricate the mucous membranes in the vagina. Without it, we’d be way more likely to experience tears, sores, painful sex, and STIs. Never thought we’d be saying this, but discharge is your BFF.
