No, there can be some "leaking" of semen even before ejaculation. The penis often produces lubrication, popularly called precum, particularly when erect. Although this is mainly clear seminal fluid (or semen) it can contain some sperm and it is possible for a girl to get pregnant from it if it is introduced into her vagina.

What does convection occurs in?
Convection only occurs in fluids. Fluids are gases or liquids.
Rarefaction occurs only in?
Rarefaction only occurs in a longitudinal wave. Rarefaction is the reduction of the density of a medium. It is the opposite of compression.
Does friction occurs only between solids?
NO
Could your girlfriend get pregnant if you inserted your penis in her vagina but didn't ejaculate?
As long as you are correct and you really did not ejaculate any semen, then pregnancy is impossible. Many published studies have shown that pre-ejaculate (also known as Cowper's fluid) does not contain sperm, and so cannot make anyone pregnant. (Some authorities hypothesize that pre-ejaculate may contain sperm cells if the fluid is released shortly after a previous ejaculation.)PLEASE NOTE -- even though passing sperm through pre-ejaculate is extremely unlikely, sexually transmitted diseases can easily be passed through pre-ejaculate.People who say they got pregnant (or know someone who did) "from pre-ejaculate" are probably kidding themselves. What really happened in these cases is that the guy accidentally ejaculated some semen inside before pulling all the way out. Remember, it only takes one sperm cell meeting one egg to cause pregnancy!Men can feel ejaculation. Ejaculate (containing sperm) is forced out by an involuntary muscular contraction deep inside the man. The problem is that by the time he feels that very pleasurable feeling of ejaculating, it's too late. The feeling of ejaculating is fantastic, but you have to pull all the way out before even the very first shot.NOTE: there is no particular sensation at all from oozing pre-ejaculate. It does not "shoot".It is theoretically possible for a man to withhold ejaculation, or to withdraw immediately before ejaculation, but this requires exceptionally good control. If you're not ready for pregnancy, it's better to withdraw early and finish "by hand" or use a condom.

What causes spermaturia?
The reason for semen in urine is due to either a previous ejaculation and the remainder of semen leftover in the urethral duct is released along with the urine. However this is not the only reason for semen in urine, it could also be due to the natural release of semen by the prostate gland or the lee ejaculatory fluid from the Cowper's gland (located directly under the prostate). I would really recommend looking at a diagram of the male reproductory system in order to make sense of the path of urine and semen.
Your semen does not shoot out why?
* Maybe you've maybe just begun puberty and ejaculation and are only making small amounts of semen * Remember not everyone shoots out semen. With some it just shoots out a little bit. * Everyone is different. Just be happy with who you are.
What is the possible semen count to produce a child?
Average is 111 million per ejaculation, give or take. It only takes one to produce a child. The more there are the better the chances, but it only takes one.
Does A man can only release sperm once?
No. Sperm can be present in fluids released before ejaculation.
Is it normal to precome during passionate kissing but still being flaccid?
I'd say yes. It's not really a precum but the lubricant that helps the semen slide without friction during ejaculation. Some people call it precum but it contains no semen at all... only lube. =)
Why is semen clear?
Normal semen, the ejaculate fluid that contains sperm, nutrients and lubrication is clear to white. Yellow, pink or red blood tinged ejaculate is a sign of infection and should be evaluated by a health care provider.
Should you be scared if you ejaculate at 13?
No, 13 is the average age. Once you have begun Puberty you will become sexually active with masturbation. At first a boy will have dry orgasms or a little clear semen on ejaculation. This will turn to ejaculating sperm in the semen as you pass through puberty onward to adulthood.
How does semen help sperm function?
Semen is the fluid that ejaculates from the Penis. Sperm makes up only about 3-5% of the liquid in an ejaculation. The rest of that liquid is there to flush it from the penis & carry it along into the vagina. Once in the vagina the semen which is full of sugars & acids, feeds and protects the sperm. The sperm are actualy living cells that carry the DNA information that the egg needs to start dividing and making a baby.
What tube carries semen in men?
The Urethra is a tube that carries both urine & semen out of the body. Only occurs in males.The urethra
You got hit in the testicles and now your semen is yellow is that bad?
YES but they will probably heal themselves Seminal vesicles are paired structures located behind the prostate gland. Sperm from the testicles (which account for only 1-2% of the semen) travel up a series of tubes on each side to join the seminal vesicles forming paired ejaculatory ducts. These structures empty into the urethra. At the time of ejaculation, fluid is discharged from the prostate gland and ejaculatory ducts into the urethra (urinary canal) forming the semen. Trauma can change this. In addition to this, with the onset of sexual excitement, specialized glands in the urethra called Cowper glands, produce a clear, somewhat sticky fluid to lubricate the urethra. this is called this pre-ejaculate (precum). Normal semen is somewhat viscous, opalescent and whitish gray in color. However, with certain factors including frequency of ejaculation, general health, diet, trauma and medications etc., the volume, consistency and color of the semen can and will vary. A yellow cast to the semen, is quite common and within normal. If you take multivitamins, this can be a cause. Thickened semen usually occurs if one ejaculates infrequently and is due to concentration of that portion formed in the seminal vesicles. Occasional clear semen, is not a specific sign of disease. A brown or red tint to the semen is a sign of bleeding, usually from the prostate gland but could be from the trauma. It is best to have this evaluated by a urologist.
Where does the fertilized egg stay?
through sperm that is in semen. it only takes one sperm to fertilize an ova (egg). there are millions of sperm in semen during ejaculation. when a sperm and egg meet and combine successfully, fertilization occurs. (in mammals this successful combination produces an embryo.)
Can over ejection of sperm stop its production?
Repeated ejaculation over a short period of time will have the effect of reducing the volume of semen and somewhat affect the number of sperm cells present in each successive ejaculation. The body however, produces enough of each that even a miniscule amount of ejaculate has the capability of producing a pregnancy. Depending on the overall age and health, the refractory period the body needs to build up to full capacity again, can range from only an hour to several days. Someone would have to masturbate or have intercourse repeatedly, to the point of injury, before he would completely stop producing any semen or sperm cells during ejaculation.
