Anatomical terminology

The urinary meatus[a] (/mˈtəs/, mee-AY-təs; pl.: meatus or meatuses), also known as the external urethral orifice, is the opening where urine exits the male and female urethra. It is where semen also exits the male urethra. The meatus has varying degrees of sensitivity to touch.

In human males

Drawing of male internal sexual anatomy

The male external urethral orifice is the external opening of the urethra, normally located at the tip of the

micturition. In some cases, the opening may be more rounded. This can occur naturally or may also occur as a side effect of excessive skin removal during circumcision. The meatus is a sensitive part of the male reproductive system
.

In human females

Lateral anatomical view of the female reproductive system

The female external urethral orifice is the external opening of the

sagittal cleft with slightly raised margins. To its left and right are the openings of the Skene's glands
.

Some evidence exists to suggest that the

penetrative sex. Orgasm from penetration alone is observed to be more likely as CUMD decreases.[1]

Evidence also suggests that decreased distance from the vaginal opening to the urethral meatus is associated with recurrent post-coital urinary tract infections. [2] Surgical repositioning of the distal urethra to prevent recurrent post-coital urinary tract infections has been employed with some success by Russian physicians.[3]

In other mammals

Unlike most other mammals (including human), female spotted hyenas have a urinary meatus that is located on the clitoral glans.[4][5]
