If your sex education stopped at "the clitoris is the small thing at the top of the vulva," you got about 10% of the picture. The clitoris is a complex, mostly internal structure that wraps around the urethra, runs alongside the vaginal canal, and connects to a network of erectile tissue most people have never seen named. Knowing the actual map changes what touch feels best, why some positions land harder than others, and what's happening when something often vaguely called "the G-spot" gets stimulated.
This piece is a clear, anatomically accurate tour of the clitoral network. No shame, no euphemism, no Victorian fog.
The shape of the clitoris
The visible part — the glans clitoris — is about the size of a pea. The internal part is much bigger. The full clitoris is roughly wishbone-shaped, with the glans at the apex and two long arms (the crura) extending downward and backward, hugging the vaginal canal on either side. Below the crura sit two bulbs of erectile tissue (the vestibular bulbs) that flank the vaginal opening and inflate during arousal.
Total length, including the internal portion: typically 9–11 cm. The visible glans is just the tip.
How the network connects
Think of the clitoris as the central node of a wider system:
- Glans clitoris — the visible nub at the top of the vulva, packed with nerve endings (around 10,000, more density per square millimetre than anywhere else in the body).
- Clitoral hood — the protective fold of skin covering the glans. Pulling it back exposes the glans for direct stimulation; leaving it covered cushions sensation.
- Crura — the two internal "legs" of the clitoris, made of erectile tissue, extending alongside and slightly below the labia.
- Vestibular bulbs — paired bulbs of erectile tissue beside the vaginal opening. They engorge during arousal and contribute to the tightening sensation people feel during sex.
- Urethral sponge — spongy erectile tissue surrounding the urethra. This is the area most people are talking about when they say "G-spot" — the felt-as-a-ridge zone on the upper wall of the vagina, accessible a couple of inches in.
All of these structures are connected, share a common nerve supply (primarily the dorsal nerve of the clitoris and the pudendal nerve), and respond together during arousal.
Why "G-spot" is misleading
The G-spot is not a separate organ. It's the urethral sponge — internal clitoral tissue felt through the upper vaginal wall. When people stimulate the area and feel pleasure, what's actually being stimulated is the back side of the clitoral network. This is why some people find penetration alone less satisfying than they expect, and why combining penetration with external clitoral stimulation tends to be the highest-yield combination: you're hitting the network from both sides.
This also explains why "vaginal versus clitoral orgasms" is a misleading distinction. They're the same network, accessed from different angles.
What this means for pleasure
A few practical implications:
- Pressure direction matters. The crura run downward and outward from the glans. Light, broad pressure on the mons pubis (the soft pad above the glans) often feels different from light pressure to either side of the labia, because you're pressing on different parts of the same internal structure.
- The C-spot, A-spot, and U-spot are all the network. Different angles of clitoral tissue. Don't get bogged down in the alphabet — just experiment with where pressure feels best.
- Combined stimulation almost always feels bigger. External glans + internal pressure on the urethral sponge engages the network from two directions simultaneously.
- Arousal time changes the geography. When the network engorges, the internal structures swell and become more sensitive. This is why ten minutes of warm-up makes everything feel different.
Anatomy varies — and that's the rule
Glans size, hood thickness, internal arm length, and bulb size all vary considerably between individuals. So does where the urethral sponge is most responsive. There is no "right" map of pleasure for your specific body — your map is yours, and it's worth taking the time to draw it.
How to map your own pleasure
Solo time, no agenda except curiosity:
- Spend ten minutes warming up before you touch anything genital. The network responds to anticipation.
- External: try light, broad pressure on the mons; light direct pressure on the hood-covered glans; firm pressure on either side of the labia (the crura sit there).
- Internal: with adequate lubrication, explore the upper wall of the vaginal canal a couple of inches in. The texture changes — that's the urethral sponge.
- Combine: external clitoral pressure with internal pressure simultaneously. Notice which combination feels biggest.
- No goal. The point is the map, not an outcome.
Key takeaways
- The clitoris is mostly internal — about 90% of the structure is below the surface.
- Glans, hood, crura, vestibular bulbs, and urethral sponge are all part of one network.
- The "G-spot" is the urethral sponge — internal clitoral tissue felt through the vaginal wall.
- Combined external and internal stimulation engages the network from both sides.
- Anatomy varies. Your map is yours.
Frequently asked questions
Is the G-spot real?
The sensitive area is real — what we've been calling "the G-spot" is the urethral sponge, part of the internal clitoral network. The standalone-organ version of the G-spot isn't backed by anatomy.
Why does clitoral stimulation feel so different from penetration?
You're stimulating different parts of the same network. The glans has the highest nerve density in the body; the urethral sponge has different texture and pressure sensitivity. Most people find combined stimulation engages the network most fully.
Are all clitorises the same size?
No — there's substantial variation in glans size, hood thickness, internal arm length, and bulb size. None of this is correlated with pleasure capacity.
Can clitoral anatomy change after childbirth?
The structures themselves don't change, but pelvic floor tone, blood flow, and hormonal background do. Most postpartum changes in pleasure resolve as the pelvic floor recovers; pelvic-floor physiotherapy speeds that up considerably.
