9 and 14. The urethral sponge]]
The urethral sponge is a spongy cushion of tissue, found in the lower genitals of females, that sits against both the pubic bone and wall, and surrounds the urethra.
Functions
The urethral sponge is composed of
erectile tissue; during
sexual arousal, it becomes swollen with blood, compressing the urethra, helping, along with the pubococcygeus muscle, to prevent
urination during sexual activity.
Female ejaculation
Additionally, the urethral sponge contains the Skene's glands, which may be involved in female ejaculation.
Sexual stimulation
The urethral sponge encompasses sensitive
nerve, and can be stimulated through the front wall of the
vagina. Some women experience intense
pleasure from stimulation of the urethral sponge and others find the sensation irritating. The urethral sponge surrounds the
Clitoris nerve, and since the two are so closely interconnected, stimulation of the clitoris may stimulate the nerve endings of the urethral sponge and vice versa.
Some women enjoy the
doggy position of sexual intercourse for this reason, because the
Human penis is often angled slightly downward and can stimulate the front wall of the
vagina, and in turn the urethral sponge.
Relation with the G-spot
The urethral sponge is an area in which the G-spot (Gräfenberg Spot) may be found.
[ Although the G-spot may exist, it has been doubted by various researchers. A team at The King's College in London, the biggest study on the G-spot's existence thus far, and involving 1,800 women, found no proof that the G-spot exists. The authors of the study concluded that the "G-spot" may be a figment of people's imagination, which has been encouraged by magazines, sex therapists and suggestive therapeutics.] Other studies, using ultrasound, have found physiological evidence of the G-spot in women who report having orgasms during intercourse.[See page 98 for the 2009 King's College London's findings on the G-spot and page 145 for ultrasound/physiological material with regard to the G-spot. ]
