How is semen produced?
You enjoy shooting it often enough and you always expect a fresh supply to be there for your next session, but how is boy sap produced?
Sperm cells are produced in the testicles (testes) in a process known as spermatogenesis. Partially mature sperm cells are constantly moving into a structure called the epididymis, which then secretes a fluid that helps the sperm cells to finish maturing.
When they’re quite ready, the tiny sperm cells enter the vas deferens, a tube of about 18 inches long that loops over the bladder. As the production of seminal fluid is more or less constant in man and some animals, while its discharge is intermittent, there are what are known as seminal vesicles which serve as reservoirs for your cum, preserving it until required, or allowing it to undergo absorption. Seminal fluid is always on tap after the age of puberty.
These seminal vesicles secrete a thick liquid rich in sugar (specifically, fructose – commonly found in fresh fruit), which is an important nutrient for the sperm cells.
Meanwhile, the prostate is a donut-shaped organ under the bladder which secretes an alkaline fluid that accounts for up to a third of the non-sperm portion of your cum.
To complete the magic formula, your Cowper's glands, secrete a mucus that lubricates and readies the urethra prior to shooting your load. You will probably know this as "pre-cum."
All of this clever equipment kicks into high gear to prepare for an ejaculation when you are jacking off or having sex. At the same time, your balls enlarge as they become congested with blood, and the seminal vesicles, prostate, and Cowper's glands work in harmony to secrete the cocktail you call cum. The actual blowing of your wad is achieved through a combination of a build up of physical and mental stimulation and the sheer volume of cum ready and waiting to be ejaculated.
