Patient's question:
Having sex with my girlfriend for the first time, I felt her lower body as if it were one whole, completely different from what I had seen in books and on TV. Following the instructions was really difficult. After searching for a long time, I found the vaginal opening, but I always couldn't figure out where the urethral opening was.What kind of help I need: Where is the urethral opening in a woman?
Doctor's answer:
The urethra is a tube that extends from the bladder to the outside of the body. The male urethra is long and narrow, about 18 cm in length, starting from the internal urethral orifice of the bladder and ending at the external urethral orifice. During its course, it passes through the prostatic part, membranous part, and penile part of the urethra. The male urethra serves both urinary and seminal discharge functions. The female urethra is short and thick, about 5 cm in length, starting from the internal urethral orifice and passing in front of the vagina, opening into the vaginal vestibule.In the male urethra, there is a circular band of smooth muscle called the external urethral sphincter in the membranous part of the urethra, which is under conscious control. In the female urethra, when passing through the urogenital diaphragm in the perineum, it is surrounded by the urethral vaginal sphincter, a smooth muscle that is also under voluntary control.
