A 2011 entry from the Museum of Sex by Melodiousmsm explores the internal anatomy of the clitoris, whose extent wasn't fully mapped until 2005, when Royal Melbourne Hospital urologist Helen O'Connell published her groundbreaking MRI studies. The clitoris forks internally like a wishbone, and then ramifies further. As Melodiousmsm notes, this suggests that the argument over vaginal versus clitoral orgasm has been misplaced, since the clitoris runs through the vulva and vagina.
The most interesting part of this article are the longstanding misperceptions about clitoral anatomy, the fact that science understood so little about such a significant organ for so long. The clitoris, after all, is the only organ that exists purely for the purpose of conveying pleasure, and has as much erectile tissue as a penis, but somehow it was mostly missed for literally millennia.
The glans is connected to the body or shaft of the internal clitoris, which is made up of two corpora cavernosa. When erect, the corpora cavernosa encompass the vagina on either side, as if they were wrapping around it giving it a big hug!
The corpus cavernosum also extends further, bifurcating again to form the two crura. These two legs extend up to 9cm, pointing toward the thighs when at rest, and stretching back toward the spine when erect. To picture them at rest, imagine the crura as a wishbone, coming together at the body of the clitoris where they attach to the pubic symphysis.
Near each of the crura on either side of the vaginal opening are the clitoral vestibules. These are internally under the labia majora. When they become engorged with blood they actually cuff the vaginal opening causing the vulva to expand outward. Get these puppies excited, and you’ve got a hungrier, tighter-feeling vaginal opening in which to explore!
