Some medicines will cause 'retrograde' ejaculation - your semen goes into the bladder, presumably. This can be just a thing that happens with some men.
If pain is involved when ejaculating, then you go to a doctor, soon.
I would want to find out ASAP why there was blood in the ejaculate. It's not the blood that's the problem, it's why there is blood that you should be concerned with.
a normal man ejaculate semen about one tea spoon or big spoon.
When you masturbate, you ejaculate "semen", which consists of seminal fluid that comes from your prostate, and sperm, which comes from your testicles.
it depends because if your in puberty its normal to ejaculate very often
Yes, it can. Of course, not as much as the ejaculate of semen that comes next. It is often enough to make a girl pregnant.
If your ejaculate is coming out pinkish, I would suspect it to be tinted by diluted blood. Even though it may just be a bit of blood in your semen, I would go immediately to see a Urologist, because blood in any amount should NOT be in your ejaculate. It may not be life threatening, but you should see a doctor that specializes in this area. Don't put it off and don't be embarrased to see a Urologist; they examine the scrotum and penis a hundred times a day. Pinkish ejaculate is NOT NORMAL. GOOD LUCK!
It probably is semen, or perhaps pre-ejaculate, but it doesn't prove anything. Most guys get erections, and erections often leak pre-ejaculate, which is a clear liquid before the semen comes out. Or it could mean that he has masturbated, also very common.
it means you should probably go to a doctor and ask a professional
Nothing to worry about, is a natural and normal discharge, if you have reason to be concerned of having a disease however, you should go for a check up.
Semen is the term for the mixture of fluid and sperm
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.
Semen will vary day to day and every man is different. There is no right consistency. On average it will be some what thick, but watery is normal also. It also depends on how often you ejaculate. If you ejaculate once a week, then semen will be thick. If you ejaculate several times a day, it will be thin and watery (but still with millions of sperm in it).
