Clitoris anatomy

Short answer

The visible part of the clitoris, the glans, is only the tip of an organ that extends several inches inside the body. Its body, legs (crura) and bulbs wrap around the urethra and vaginal opening and fill with blood during arousal. Its only known function is sexual pleasure.

  • The glans is the visible tip; most of the clitoris is internal.
  • Internal parts wrap around the urethra and vaginal opening.
  • It swells with blood during arousal, much like erectile tissue.
  • Many women need direct or indirect clitoral stimulation to orgasm.

What are the parts of the clitoris

The clitoris is shaped roughly like a wishbone, with the glans at the top and two pairs of structures reaching back and down inside the body.

Part Where it is What it does
Glans Visible tip, under the hood Most sensitive point, dense with nerve endings
Hood (prepuce) Fold of skin over the glans Protects the glans from friction
Body (shaft) Runs up and back from the glans under the skin Connects the glans to the deeper parts
Crura (legs) Two legs running along the pubic bones Anchor the clitoris and fill with blood
Vestibular bulbs Either side of the vaginal opening Swell during arousal and add pressure and sensation
Suspensory ligament Attaches the body to the pubic bone Holds the structure in place

The whole organ measures about 3.5 to 4 inches from the tip of the glans to the ends of the crura. Most of it sits underneath the inner and outer labia, next to the urethra and around the vaginal opening. For how these sit among the other external parts, see vulva anatomy.

What happens during arousal

The body, crura and bulbs contain erectile tissue. When arousal starts, blood flows in and the tissue swells. This has several effects:

  • The glans becomes larger and more sensitive, and may pull back under the hood as arousal peaks.
  • The bulbs swell around the vaginal opening, which can make that area feel fuller.
  • Pressure on the front wall of the vagina presses on clitoral tissue from the inside. This is one reason the front wall is sensitive for many people.

After orgasm, or when arousal fades, blood drains away and the tissue returns to its resting size. Some people find the glans very sensitive for a short time afterward.

Why does the clitoris matter for comfortable sex

Arousal is not only about pleasure. It also prepares the body for penetration. The vagina lengthens, the cervix lifts, and lubrication increases. Moving to penetration before arousal builds is a common reason for friction and pain.

Practical points:

  • More time for clitoral and external touch before penetration often means less discomfort.
  • Lubricant reduces friction on the glans and the vaginal opening.
  • Positions where the clitoris gets contact or pressure can make sex more comfortable and more satisfying.
  • The lube finder can help you pick a lubricant type that suits your body and activities.

How does the clitoris change over a lifetime

  • Puberty. The clitoris grows along with the rest of the vulva.
  • Pregnancy. Increased blood flow can make the area more sensitive or swollen.
  • Menopause. Lower estrogen and testosterone can reduce blood flow. The glans and hood may become smaller and the tissue thinner, and arousal may take longer. See menopause and sex.

Some medicines, including certain antidepressants and hormonal treatments, can reduce clitoral sensation or delay orgasm. If you notice a change after starting a new medicine, mention it to your prescriber rather than stopping on your own.

Which conditions affect the clitoris

Clitoral adhesions

The hood can stick to the glans, trapping skin cells and secretions underneath (called smegma). This can cause itching, pain or reduced sensation. Adhesions are more common with lichen sclerosus and after menopause. A clinician can check by gently retracting the hood.

Lichen sclerosus

A long-term skin condition that causes itching and white, thin, shiny patches on the vulva. Over time it can cause the hood to fuse over the glans. It responds well to treatment, which is why itching that does not go away needs a proper look.

Clitorodynia

Pain localized to the clitoris without an obvious cause. It is a form of vulvodynia and may involve irritated nerves or a tight pelvic floor. A clinician who treats vulvar pain, often alongside a pelvic floor therapist, can help.

Persistent genital arousal

An uncommon condition of unwanted, distressing arousal sensations that do not settle after orgasm. It is real, it is treatable, and it deserves specialist care.

What about piercings and cosmetic surgery

Hood piercings sit in the skin over the glans rather than in the glans itself. Like any piercing, they carry a risk of infection, bleeding and nerve irritation, and should only be done by an experienced piercer using sterile equipment.

Surgery that reduces the hood or the labia is sometimes marketed for appearance. The clitoris and its nerves run close to these areas, and loss of sensation is a known risk. ACOG advises caution with cosmetic genital procedures, as normal variation in size and shape rarely needs changing.

Why the clitoris was left out for so long

Detailed anatomy of the internal clitoris was only widely published in the late 1990s, and many textbooks still show only the glans. That gap still shapes how sex is taught and how pain is assessed. Knowing the full structure helps make sense of how arousal works, why the opening and the front wall of the vagina are so sensitive, and why stimulation of the glans matters for most people.

Quick questions

Is it normal not to orgasm from penetration alone?

Yes. Most women do not orgasm from vaginal penetration without some clitoral stimulation, from fingers, a toy, positioning or a partner's body. That reflects how the clitoris is built and positioned, not a problem with you or your partner.

Can the clitoris get bigger?

It swells temporarily with arousal. Lasting changes in size can happen with hormone shifts, for example during pregnancy or with testosterone treatment. A noticeable, unexplained enlargement in an adult is worth mentioning to a clinician so hormone levels can be checked.

Why does direct touch sometimes feel too intense?

The glans has a very dense concentration of nerve endings, so direct pressure can feel sharp rather than pleasant, especially before arousal builds. Touching through the hood, using lubricant, or stimulating the area around it is often more comfortable.
