You bet! Age is not a deterrent - stamina is
Men produce sperm for the purpose of reproducing.
Oh yes all it takes is one sperm to make you pregnant.
Sperm is produce continuously by the body
Yes, if the sperm is in the egg, the egg is fertilized.
How does it works does the sperm needs to go inside a girl to get pregnant if not are we okay if it doesn't go inside
This is something I cannot answer. If you are old enough to produce sperm, then you have enough to get a girl pregnant. A male is capable of releasing small amounts to over a billion sperm when he ejaculates (http://www.livescience.com/mysteries/080606-llm-sperm.html). So, even if you don't ejaculate, but there is semen that comes in contact with your partner, she can become pregnant.
No. At 6, the male body is not developed enough to produce sperm.
If said 9 year old is producing, but rare at that young an age
It is not likely. Because the testis hasn't matured enough to produce fertile sperm.
I think your asking if you can get a woman pregnant with a 3 inch penis. If you produce sperm you can usually have a baby.
You can't really do anything to produce fast sperm. It all depends on your wife's ovulation schedule as to when she might get pregnant. You can try at home ovulation kits, they might help you get an idea as to when the best time for your wife to get pregnant is. As far as if you are trying for a girl or boy keep in mind the "slow" sperm you produce is stronger and equals girl where as the "fast" sperm is weaker and will produce a boy.
No. Besides a boy HAS to produce sperms. There is no such thing as a boy who doesn't produce sperms.
Whenever the male begins to produce sperm he can get a girl pregnant.
No, because when the sperm doesn't enter the vagina to the egg, a baby can't be produced
If the drug is working the sperm count doesn't make a difference.
Yes. Being gay has nothing to do with sperm strength.
Provided you are not sterile and still produce sperm, yes.
