The urinary meatus [a] (/ m iː ˈ eɪ t ə s /, mee-AY-təs; pl.: meati or meatuses), also known as the external urethral orifice, is the opening of the penis or vulva where urine exits the urethra during urination. It is also where semen exits during male ejaculation, and other fluids during female ejaculation. The meatus has varying degrees ...
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.
The perineal sponge is composed of erectile tissue; during arousal, it becomes swollen with blood compressing the outer third of the vagina along with the vestibular bulbs and urethral sponge thereby tightening the vagina and increasing stimulation for the vagina and a penis, if involved.
The vulva encompasses everything down there, including your labia majora, labia minora, clitoris, vaginal opening, and urethra opening. “People commonly confuse these two v-words,” Dr. Talib says.
A Skene's duct cyst, pressing the urethral opening towards the right side of the image. Disorders of the Skene's glands may include: Infection (called skenitis, urethral syndrome, or female prostatitis) [12] Skene's duct cyst: lined by stratified squamous epithelium, the cyst is caused by obstruction of the Skene's glands.
The urethral sponge is composed of erectile tissue; during arousal, it becomes swollen with blood, compressing the urethra, helping, along with the pubococcygeus muscle, to prevent urination during sexual activity. [citation needed]
Research indicates that the vestibular bulbs are more closely related to the clitoris than to the vestibule because of the similarity of the trabecular and erectile tissue within the clitoris and bulbs, and the absence of trabecular tissue in other genital organs, with the erectile tissue's trabecular nature allowing engorgement and expansion during sexual arousal.

In the human female, the urethra is about 4 cm long, [10] [12] having 6 mm diameter, [12] and exits the body between the clitoris and the vaginal opening, extending from the internal to the external urethral orifice. The meatus is located below the clitoris.
