The clitoral bulbs extend internally and swell during arousal.
When a woman becomes aroused, her body responds by becoming more sensitive to touch. The external portion of the clitoris can become harder and fuller as blood flows into it. However, this is just the tip of the iceberg. When a woman becomes aroused, the internal part of the clitoris also becomes larger and extends into the vagina. This is known as the "clitoral bulbs." They are small, spongy structures that are located on either side of the urethra (the tube through which urine exits the body) and they extend outward toward the bladder. As a woman becomes more aroused, these bulbs will swell and increase in size. In some women, they may even protrude slightly from the vaginal opening. This can be seen when a woman is sexually stimulated, especially if she has an orgasm.
The reason for this response is still unknown, but scientists believe that it's due to increased blood flow to the area. It's thought that as a woman becomes aroused, her body increases blood flow to the genitals to help with sexual pleasure. This increase in blood flow causes the clitoral bulbs to swell, making them bigger and more noticeable. Some researchers have suggested that the purpose of this swelling is to make it easier for a partner to find and stimulate the G-spot (a spot inside the vagina that is believed to produce intense pleasure when touched). Others think that it's simply a way for the body to prepare itself for possible intercourse by increasing sensitivity in the genital region.
Whatever the reason, many women report feeling intense pleasure when their clitoral bulbs are stimulated. Some say that it feels like a wave of warmth or pressure that begins in the pelvis and moves up towards the stomach. Others describe it as a tightening sensation that radiates throughout the whole body. Whether you enjoy having your clitoral bulbs stimulated during foreplay or intercourse, understanding how they work can help you explore your own body and discover new ways to pleasure yourself (or your partner).
