What is semen and pre-ejaculate fluid?

Answer 1

Cum is called Ejaculate and is 90% water and the rest is Semen which is milky opalescent, and opaque. Opalescence increases when the ejaculate has a higher concentration of sperm. 65% of the semen arises from the seminal vesicles,35% of the semen comes from the prostate. It is the semen from the prostate that gives semen its characteristic smell and the remaining 5% is of other fluids (citric acid, free amino acids, fructose, enzymes, phosphorylcholine, prostaglandin, potassium, and zinc). When a man orgasms he ejaculates between 1 and 5 milliliters of semen. The average is 2 to 3 milliliters (a small teaspoon) Pre-cum is pre-ejaculate (also known as pre-ejaculatory fluid or Cowper's fluid), it is a clear lubricating fluid that is issued from a man's penis when he is aroused.
