Thin Watery Cum

From the Mail Bag: 

"I stumbled upon your blog quite recently and even though I only expected to do a quick sweep I found myself staying. It has been 5 days now and I have been working through each and every post. I enjoy what and how you do it! I have a ... a question... When I cum my semen is thick and milky and my friend says I shoot so much he cant swallow. But when he cums it is thin and watery. Why does semen differ like this? Sometimes we just jack off and either he uses my cum as lube or I his and I have noticed this difference. Also when he cums on me it burns, like really burns, my cum just feels warm when I cum on myself. Do you know why this is and is that why his cum is more watery than mine?"

So, all we can attribute the heat to is his normal body heat. The groin is naturally warmer - as are the underarms - than the rest of the body. Add in sexual arousal and activity of any kind and the heat quotient rises - especially around the genitals. I don't think it's anything he needs to truly worry about.

Watery semen - called Oligospermia - can be attributed to many factors but the primary reason is low sperm count. The lower the natural sperm count, the thinner - or, more watery - the fluid will seem. According to Healthline, these other issues can contribute to thin semen:

• Varicocele. A varicocele is a swelling of veins from the testicles in the scrotum. It’s a major, but treatable, cause of male infertility.
• Infection. Examples include a sexually transmitted disease such as gonorrhea or another kind of infection that causes inflammation of a reproductive organ, such as epididymitis.
• Tumors. Malignant and benign tumors in the testicles may affect sperm production.
• Hormone imbalances. Hormones produced in the testicles, pituitary gland, and hypothalamus are all necessary to produce healthy sperm counts. Changes in any of these hormones could affect sperm production.

Other causes of low sperm count can be: Retrograde ejaculation (most of the semen is ejected into the bladder); anti-sperm antibodies in the immune system; injuries (or other problems) with the spermatic cords.

Frequent ejaculation can also contribute to watery semen. If a guy cums multiple times in a day, it can become thinner with each ejaculation. That can be remedied by allowing sufficient time (at least a couple of hours) for the testicles to produce a more normal amount of sperm.

Another possible cause of thin, watery semen is Zinc deficiency. 

Proper levels can help fight off any (possible) sperm antibodies produced by the immune system which mistakenly react to sperm as a foreign body, resulting in thicker cum.
