Addiction of masturbation is a serious problem it lead to damage tissue and nerves which cause hypersensitivity of penis that ultimately leads premature ejaculation, ED etc.
Masturbation weakens the hormone responsible for producing sperm
Masturbation makes a man moan, suffer and starve for real sex during the period of masturbating.
It reduces the period of ejaculation in men.
Masturbation weakens the womb in females thereby not enabling the womb to carry a child which leads to abortion (miscarriages most of the time)
It can cause sperm disability which leads to abnormal children (in fewer cases).
Due to damage of tissue and nerve penis size not increase ,it always decrease day by day and cause sexual issue
