You can not ejaculate until your body is ready for it, puberty, and ejaculation and masturbation is not harmful in any way.
Puberty has to have begun before you can ejaculate sperm. Puberty will begin when the body is ready which can be anytime from 7 to 18 in extreme cases, but on average around 11 to 13. There are no harmful effects if it is done (masturbation) in moderation.
females do not produce sperm
Artificial insemination (AI) is the process by which sperm is placed into the reproductive tract of a female for the purpose of impregnating the female by using means other than sexual intercourse. In humans, it is used as assisted reproductive technology, primarily to treat infertility using sperm from the woman's partner, or sperm from a sperm donor (donor sperm) where the male partner produces no sperm. It is also increasingly used to enable women without a male partner (i.e., single women and lesbians) to produce children by using donor sperm. In cases where donor sperm is used the woman is the gestational and genetic mother of the child produced, and the sperm donor is the genetic or biological father of the child.
Producing sperm has nothing to do with your penis; that's all about the testicles.
There is no race in the sense of a competition, all sperm are equally affected by the chemical signals. When the sperm reaches the egg, its tail is cast off; thus disposing of male mitochondrial material; and the egg is immediately changed by the entry of the sperm so that another sperm cannot enter. Then follows the joining of the two DNA strands etc.
It is located within the "head" of the spermatozoa

Ejaculating a lot of sperm has no effect on your age.

The urethra passes the urine out of the body.
The benefits are a small amount of protein and glucose. Other than that there are no harmful effects of swallowing semen.
Nothing really im 21 and ejected it at age 11
In warm, moist conditions, it could be for days.
No, there is no harmful effects from getting semen in your eye other than a slight irritation possible.
The urethra is responsible for ejaculating sperm and expelling urine in men.
No. Sperm is a living entity and regenerates as it is needed, you arent using it up, dont worry there is plenty.
