Is it bad, harmful, or dangerous to come too much? I have a girlfriend and we fool around pretty often. I cum alot. Is this bad? Will this hurt me in the future when I want to have kids and a family?
No — it is not bad to come (ejaculate) frequently, and it does not affect whether or not a man will be able to have children. The time when sperm is first produced is called spermarche. Men's bodies make sperm all their lives. New sperm develop every minute.
Sperm are made in the testicles. There are millions in every drop of healthy semen (fluid containing sperm that is ejaculated during sexual excitement.) The sperm move from the testicles to the seminal vesicles through tubes called the vas deferens. In the seminal vesicles, they mix with other fluids to form semen.
During sexual excitement, sperm move out of the testes and into the urethra through tubes called the epididymis. They mix with several fluids to produce semen, which comes out of the penis through the urethra when a man ejaculates. Usually, a teaspoonful to a tablespoonful of semen is released with each ejaculation. Each time a guy ejaculates, his semen contains about 300 million sperm. It only takes one of these to cause pregnancy.
Recent studies have shown that the more often a man ejaculates, the more sperm he develops, which explains why men never use up all their sperm.
Hope this information helps!
