Sex experts assure men that penis size is not a major factor in how a man performs in bed. They insist that it is the quality of love-making that matters, not the length of the male organ.

However, an Indonesian woman opted to believe otherwise. Unfortunately, the victim of her misconception was not her husband or lover, but her 9-year-old son whom she killed because she was worried that his small penis would affect his future prospects.

The 38-year-old woman from Jakarta drowned her son in their bathtub, dressed him and laid him on the bed. Later, she went to the nearby police station turned herself in and admitted to the crime.

Police said the woman was aware of what she did and ordered her to undergo a psychological test to assess her mental condition.

The report did not state the size of the deceased child's penis, but said the child already had a small organ before undergoing circumcision which appeared to further shrink his vital body part.

Most boys normally have small penises, but major changes in their reproductive system takes place during puberty, including growth of pubic hair as well as changes in other body parts.
