If one doesn't ejaculate for a while...?

Josie

Semen is only produced "on demand" by the prostate and seminal vesicles, so is not there until you masturbate. Sperm are manufactured on a 100 day production line and stored until they die. Production is cut down if you don't have sex or masturbate.

Seminal fluid is mainly produced on demand, kinda like when you produce saliva. So it is not "stored up" but if you get horny you might get a full sensation if you don't ejaculate. But that will get absorbed as well or gradually released in your urine.

No, after a time, a man will have a wet dream. Wet Dreams – Nocturnal Emissions – Nightfall. The male human body secretes semen continuously. It is stored in the two seminal vesicles. When they get full the semen has to be discharged. It can be done by sexual intercourse or by masturbation. If an individual does not have sexual intercourse or masturbates, he may expect to have wet dreams because the body has to discharge the load of semen. You are having wet dreams. To prevent wet dreams, you need to have sex or masturbate to orgasm before going to bed. Masturbating before bedtime also helps one to sleep. https://en.wikipedia.org/wiki/Nocturnal_emission https://en.wikipedia.org/wiki/Masturbation
