Vestibular bulbs are long masses of erectile tissue. They are found inside and next to the clitoris and near the urethra, urethral sponge, and vagina. They are attached to the perineal membrane and urethra. Muscles lay over the top of them.
Vestibular bulbs are sometimes called the bulbs of the vestibule, vestibulovaginal vulbs, and clitoral bulbs.
More About Vestibular Bulbs
The vestibular bulbs are the female equivalent of the bulb of penis and part of the corpus cavernosum urethrae. Unlike men, who have a single, solid mass of erectile tissue, the vaginal opening splits the erectile tissue of females into two halves.
When a woman is aroused, her vestibular bulbs fill with blood. This cuffs the opening of the vagina, which makes the vulva swell up. It can be twice or even three times its usual thickness when a woman is aroused.
The muscles which lay over the top of the vestibular bulbs contract when a woman orgasms. These contractions might feel like they occur in the vagina or even the G-spot. However, they always occur near the vestibular bulbs.
Blood leaves the vestibular bulbs when a woman has an orgasm. If she does not have an orgasm, the blood will leave of its own accord several hours after she becomes aroused.
Unlike men, who cannot get another erection immediately after orgasm, a woman’s vestibular bulbs do not need time to recover. Multiple orgasms can be experienced with prolonged stimulation. Also, unlike men, a woman’s vestibular bulbs are not impacted by aging. While self-lubrication can be more difficult over time, her vestibular bulbs can help her have orgasms well into old age.
