muscular, expandable canal lined with mucous membranes. From its outside opening between the inner lips, yoni curves up towards the belly and cervix, the entrance to the womb or uterus. Normally the channel is collapsed upon itself so there's no space between its touching walls. When first aroused, the membranes that cover yoni's insides lubricate. As she gets more aroused, yoni opens and lengthens. Yoni's deeper two-thirds have smoother walls with fewer nerve endings than the outward third. Consequently, this inward area responds less to touch and more to pressure, like that produced from a firm, hot, cylinder of flesh. What an amazing design!     Theoutward third of yoni, the part closest to the mouth, is different in character than the inward two-thirds. Because it's dense with nerve endings, the walls of yoni's outward third are highly responsive to touch. Of course, you already knew that, right? These tissues are covered with ridges and furrows, especially around the urethra that transports urine out of the bladder.       Urethra The bladder is above the top inward end of yoni. The urethra is the medical name for the slender tube that runs along the top or front side of inner yoni and conducts urine from the bladder to the urethral opening near yoni's inner lips. The average urethra is about 1.5 inches (4 centimeters) long, which is much shorter than the similar canal in a man's vajra. Because it's so short, women are much more susceptible to urinarytractandbladderinfections. That's because germs don't have as far to travel inside, especially after deep and extensive sexual play. But don't worry, it's easy to prevent this. Just be sure to drink lots of water before, during, and after sex of any kind. And remember to empty your bladder as soon after play as you can to cleanse the canal. The opening of the urethra is technically called the meatus. It lies below clio within yoni's inner lips and near the top side of her opening. Some women's meatus is just inside the top side of inner yoni. For many women, the meatus is especially sensitive to stimulation since it's surrounded by the beginning of the urethral sponge.   Urethral Sponge There are a number of glands and tissues around yoni that can create delicious sensations with specific kinds of massage. The tissue along yoni's front or upper wall is colloquially called the G-Spot. The entire urethra is surrounded by spongy erectile tissue under the upper surface of yoni which is called the urethral sponge. The sponge is composed of up to 40 little glands and ducts referred to as paraurethral since "para" means beside or near.     Somecall the paraurethral glands the Skene's glands after the physician, Alexander Skene, who discovered and drew them in 1880. Dr. Milan Zaviacic, a medical professor at Comenius University in Slovakia, has been studying women's urethral sponges since the early 80s. He's clearly demonstrated that the tissue secretes the same chemicals produced by male prostates. Since these organs also develop from the same tissue in men and women, he and many other sexologists now use the term female prostate for the glands and ducts that surround the urethra. With sexual arousal and firm pressure, the urethral sponge swells with fluid. Though the exact physiology has yet to be completely understood, it's clear that female ejaculate comes from the urethral sponge/female prostate at least in part. Natural vaginal lubrication emanates from another source. This thicker, slippery fluid comes from the Bartholin glands, two small organs located on each side of yoni's mouth. The perineum is the sensitive tissue between yoni and rosetta (anus). Many women find
