Women actually get erections in their genitals and even though they’re smaller than the male counterpart, they are just as important, says Sadie Allison, DHS, a sexologist, founder of Ticklekitty.com and author of Tickle His Pickle–Your Hands-On Guide to Penis Pleasing. “The clitoris is made up of the same spongy erectile tissue as the penis, which expands and engorges with blood when aroused,” she explains. “You can observe this—just look at your clitoris or touch it when you’re aroused and it will be bigger.”
