Structures opening in the vulval vestibule are the urethra (urinary meatus), vagina, Bartholin's glands, and Skene's glands. [1]The external urethral orifice is placed about 25–30 millimetres (1–1.2 in) [2] behind the clitoris and immediately in front of that of the vagina; it usually assumes the form of a short, sagittal cleft with slightly raised margins.
Toxopneustes pileolus, commonly known as the flower urchin, is a widespread and commonly encountered species of sea urchin from the Indo-West Pacific. It is considered highly dangerous, as it is capable of delivering extremely painful and medically significant stings when touched.

Located at the anterior junction of the labia minora is the clitoris, a highly erogenous sexual organ. The visible portions of the clitoris are the glans and frenulum . Typically, the glans is roughly the size and shape of a pea , and can vary in size from about 6 mm to 25 mm (less than an inch). [ 12 ]
Female ejaculate may result from sexual activity for some women, especially during orgasm. [3] [4] In addition to PSA and acid phosphatase, Skene's gland fluid contains high concentrations of glucose and fructose. [3] In an amount of a few milliliters, fluid is secreted from these glands when stimulated from inside the vagina.
The openings of the Bartholin's glands are located on the posterior margin of the introitus bilaterally in a groove between the hymen and the labium minus at the 4:00 and 8:00 o'clock positions. The glands duct opening is seen on the posterolateral aspect of the vestibule 3 to 4 mm outside the hymen or hymenal caruncles lateral to the hymenal ring.
Some women experience intense pleasure from stimulation of the urethral sponge and others find the sensation irritating. The urethral sponge surrounds the clitoral 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.
