The clitoral bulbs are part of the clitoris located inside the body. They run between the labia minora and are divided into two sections known as the crura (singular crus) which form a sort of "Y" shape. One leg of the "Y" is attached to the vaginal wall at the front while the other reaches behind it towards the anus. As the legs meet they turn back upwards and insert into the shaft of the clitoris. This creates a small space where fluid builds up during arousal making the clitoris swell. The crura also move in response to stimulation, increasing sensation when touched, rubbed, licked, or sucked. Some women report feeling like their panties are being tugged or pulled down from this movement. During orgasm, the muscles contract rhythmically creating waves of pleasure throughout the pelvic floor. For many women, stimulating these areas alone or together with the glans can lead to powerful orgasms.
Research has shown that the clitoral bulbs play an important role in female sexual pleasure and arousal. Dr. Helen O'Connell, a gynecologist specializing in women's sexual health, conducted extensive studies on the structure of the clitoris and found that the internal structure was much more complicated than previously thought. Her research revealed that there are thousands of nerve endings spread throughout the entire organ rather than just the glans. She also found that the legs of the Y-shaped crura extend deep into the body, reaching as far as 10 centimeters inside the pelvis. Other researchers have suggested that this may explain why some women experience G-spot orgasms, which are characterized by intense waves of pressure felt deeper within the body. It is possible that stimulation of the clitoral bulbs could cause contractions of the urethra, bladder, and vaginal wall leading to a G-spot orgasm. However, not all women respond to G-spot stimulation so it remains unclear if this is the case for everyone.
Studies have found that the average length of the clitoral bulb is around 3 inches but varies significantly between individuals. This means that not every woman will feel stimulated in the same way during intercourse since some men cannot reach the full extent of her labia minora due to penis size or positioning. In addition, different positions can affect how much of the clitoral bulbs are touched. For example, missionary position tends to touch the sides of the labia while doggy style hits the front. Some women find that they need direct clitoral stimulation to achieve orgasm while others prefer indirect stimulation during intercourse. Others report only feeling pleasure when stimulating both the external and internal areas simultaneously. Experimenting with different positions and techniques can help women discover what feels best for them.
