Dear Mocha,

When I'm giving my bf a BJ I really like to try swallowing his cum. I know he'll love it. Is it safe to swallow semen?


Dear Sally,

Semen is the whitish/greyish fluid released by a man during ejaculation. Average volume of semen per ejaculation is 2-5 mL (.405 - 1.22 teaspoon).

Here's a breakdown of the composition of semen:

- 60% produced by seminal vesicles. Seminal fluid contains salt ions, sugars, fats, hormones, amino acids, proteins, enzymes and metals which nourish the sperm. These components also makeup for the alkaline pH of the semen. It protects the sperm from the acidity of the vaginal fluid;

- 30-35% produced by the prostate. More basic in nature than seminal vesicle secretion. It also has the effect of increasing sperm motility;

- 5% from testes and epididymis (200-500 million sperm cells).

Semen can be an indication of a man's health status. Normal semen is usually cloudy white or grayish in color. It has a chlorine smell. It is slightly sweet due to high content of sugar (fructose) produced in the seminal vesicles. Taste of sperm may vary depending on a man's diet.

You might find it surprising, but there are quite a few studies out there which discuss the health benefits of semen. Research shows that semen acts as an anti-depressant. Exposure to semen can make a woman happy. Semen contains these natural mood-boosting chemicals - cortisol, serotonin, oxytocin, prolactin, melatonin and estrone.

Recently, Austrian researchers found that spermidine, a compound found in semen, has anti-aging effects. Tests conducted on mice showed that those who were fed with spermidine lived longer and remained younger by 33% than those mice that did not receive the substance. They also found out that it could prevent Alzheimer's and Parkinson's disease.

Swallowing semen will not harm you as long as your partner is healthy and tested to be free from STDs.

Sexerly yours,



Spermidine can also be found in high concentration in grapefruits and soybeans.
