Is it is safe to waste sperm of 17 year boy?
yes because males always produce more sperm an d the unused
sperm is just made into other nutrients
meaning if you don't use it you loose it
Another answer: Once a boy reaches puberty his testes begin to
make sperm and they carry on doing this for the rest of his life,
barring acidents or diease, even if he lives to be over a hundred.
It makes no difference how many times you ejaculate sperm as your
body continually makes more. Even if you don't masturbate or have
sex of any kind your body carries on making fresh sperm and the
existing sperm is either reabsorbed back into your body or it is
ejaculated while you are alseep, in the form of a wet dream. So
don't worry even if you masturbate a dozen or more times a day you
will never use up all of your sperm.
Sperm is continually being produced and old sperm that has not
been ejaculated gets washed away with the urine to make room for
new sperm.
