Ejaculate is 90% water. Semen is a milky opalescence, and opaque. Opalescence increases when the ejaculate has a higher concentration of sperm. Ejaculate consists mainly of semen:
When a man orgasms he ejaculates between 1 and 5 millilitres of semen. The average is 2 to 3 millilitres (a small teaspoon) which of course is nothing when compared to an adult wild male boar which produces 0.5 litres per ejaculate!
An ejaculation can travel up to 3 feet or more. However an average distance is about 7 to 10 inches (17to 25cms). Ejacuation is preceded by an emission of 1-2 drops of alkaline fluid from the Cowper's glands (two small glands beneath the prostate). Its alkalinity neutralizes the acidity that remains in the urethra from recent urination. Repeated Ejaculation Facts:
The ability to have repeated ejaculation varies considerably from man to man. The ability to have repeated ejaculation begins to decline almost immediately once puberty is complete. Within the period of one to two hours most men can have one ejaculation, some can have a second and a few men can have three or four. Kinsey, a well known researcher into sex, recorded one man who was able to ejaculate six to eight times in a single session, but this is very rare.
