What does a urethral opening do?
The urethral opening allows for the passage of urine from the bladder to the outside of the body. It also allows for the passage of semen during ejaculation in males. The urethral opening is surrounded by a sphincter muscle, which helps to control the flow of urine and semen.
In females, the urethral opening is also located near the clitoris, which is the primary erogenous zone of the female genitalia. As a result, stimulation of the urethral opening can lead to sexual arousal and pleasure.
