Internal Clitoris MRI

This MRI photo shows the placement of the internal clitoris – the legs run along the pubic bone behind your outer labia and the bulbs are next to them behind your inner labia.

Internal Clitoris

Women have a quite complex sex organ. The “clitoris” refers to the clitoral glans – which has 8,000 nerve endings – is literally the tip of the iceberg outside of the body. The “legs” and “bulbs” of the clitoris are inside of the body.  The “bulbs” contain erectile tissue – we have just as much erectile tissue as men but our erections are internal. Notice the “clitoral shaft” which is like a rubber band. Run your finger from side-to-side over your clitoral shaft and notice the feeling.

Side View

Notice the clitoral glans (the circle) and the legs and bulbs of the clitoris with the labia and vaginal opening visible in the middle. You can see how the bladder sits in front of the uterus.

Urethral Sponge

The urethral sponge (referred to as the g-spot) sits on top of the vaginal opening. There is no one spot in the vagina that feels good for all women which is why Betty hates the concept of the g-spot.
The urethral sponge contains prostate-like fluid – about one teaspoon – that is what we call “female ejaculate”. The urethral sponge fills up with fluid to protect the bladder from the friction of penetrative sex.
Female ejaculation is a real response for some women. If you stimulate the urethral sponge and push out with your pelvic floor muscle, a small amount of fluid can be released. Know that female ejaculation is separate from an orgasm. Betty objects to the focus on female ejaculation because it mimics the male model of sexual response (ejaculation = orgasm). The female model of sexual response is much different and more complex – that’s why we can have multiple orgasms

Urethral Sponge w/Penetration

This is an example of penetration with fingers that engages the urethral sponge. Insert your fingers – go 2-3 inches inside – and curl your fingers up toward the ceiling of the vagina and rub softly, you will notice a positive sensation. You can do this yourself by using a curved dildo or angling your dildo up toward the ceiling of your vagina.
The positive sensation can travel up and down the urethral sponge.
Notice how the bladder is right behind the urethral sponge and in front of the uterus which is why stimulation can make you feel like you have to urinate.

Erectile Tissue

The internal clitoris and all of the pink tissue becomes erect. There is as much erectile tissue as a penis.

It takes 20 to 30 minutes of clitoral stimulation for the clitoral system to become fully erect.

The clitoris does not lose its erection after orgasm, like the male penis. Reaching orgasm again after the first orgasm is easier.  This helps women experience multiple orgasms.

Pelvic Floor Muscle

Your pelvic floor muscle is vital to your orgasm. When we squeeze and release our pelvic floor muscle (pc muscle) we bring blood into our sex organ.
Notice how muscle circles around the clitoris, your vaginal opening and your anus – like an infinity – and the pc muscle is like a sling. To engage your pc muscle, insert your finger into your vagina and squeeze – that’s your pc muscle. Clitoral stimulation with vaginal penetration (while squeezing and releasing your pc muscle) = multiple orgasms.
