Facts about vaginas.

Surprisingly accurate. Buzzfeed has historically taken a beating for click-bait and credibility, but this is pretty spot on.

29 Things Everyone With A Vagina Should Definitely Know by Carolyn Kylstra
1. The clitoris is not a button — it’s more like a wishbone. When most people think of the clitoris, they think of the small visible part. But research indicates that it actually has branches that extend down underneath the skin, along either side of the vulva, kind of in a wishbone shape. “These branches can potentially be stimulated from the outside,” Debby Herbenick, Ph.D., associate professor at Indiana University and author of The Coregasm Workout (Seal Press, 2015), told BuzzFeed Life. GOOD TO KNOW.
2. What you think is your vagina is probably actually your vulva. The vulva refers to the outside, visible parts of your genitalia. It encompasses basically everything you can see — the labia, the clitoris, the urethra, the vaginal opening, and so on — and it’s usually what most people mean when they say “vagina.” The vagina, on the other hand, is the muscular passageway that connects the vulva to the cervix.
3. Vaginas (and vulvas) come in lots of different shapes, sizes, and colors. There’s a good deal of variation from person to person, and there’s no such thing as a “standard” vulva — and that’s according to science.
4. When aroused, the vagina can expand to around twice its normal size. Unaroused, the average vagina is about three to four inches deep. But during sex it can expand to about twice as big, Dr. Herbenick told BuzzFeed Life. That’s partially because of a process called vaginal tenting, which is what happens when you get aroused. “When women become aroused, there’s more muscular tension in the body,” Dr. Herbenick says. “That muscular tension draws the uterus upward, creating more space in the vagina lengthwise.”
