The male urethra, like the female one, is divided into several parts, each with distinct anatomical landmarks. Due to its longer length and to the presence of the prostate, these landmarks are much more evident in the male urethra. Another difference between the male and the female urethra...
Themembranous urethrais about 1 to 2 centimeters long and the shortest part of the male urethra. It runs from the base of the prostate gland to the bulb of the urethra, piercing the urogenital diaphragm along its course. Thespongy urethra, also known as thecavernous urethra, is about 15 ce...

secretionsmay exit the body via the urethra as a result of asexually transmitted infection (STI).2For example, if urine were leaving the penis, then ejaculate would be blocked, as the sphincter at the base of the urethra would not allow for those fluids to mix and exit the body ...
Female orgasms most commonly come from the clitoris or clit—the primary source of female sexual pleasure. Where is the clit? Here is how to find it.
The penis is the male external excretory and sex organ. The penis contains the external opening of the urethra, which is used for urination and to deliver semen into the vagina of a female sexual partner. Erectile tissue inside the penis allows the penis to increase in size and become rigid...

Most recent anatomic studies have described the external urethral sphincter complex as consisting of an intrinsic rhabdosphincter surrounding the smooth musculature of the urethra and an extrinsic sphincter incorporating the levator ani muscle and the pelvic floor. Both form a condensed striated muscle ...
“virginity”; even at birth, this is only a partial membrane, as menstrual fluid and other secretions must be able to exit the body, regardless of penile–vaginal intercourse. The vaginal opening is located between the opening of the urethra and the anus. It is flanked by outlets...
