When a person sees a vividly
inapropro image as a young child, this may leave a mark on
the young ones life. The
young one might have seen his parents (or watched someone else) perform sexual intercourse which, at his/her age, the young one can't comprehend or process through their brain. All the young one knows is that he is scared as shit and will never see his parents the same way. Thus the child is mentally scarred.

Little Timmy saw his parents having sex christmas night. They finally found him
in the corner,
rocking himself and mentally scarred.
