During the nineteenth century, the idea of masturbation was considered to be a taboo and unhealthy practice. What was thought of as premature sexual interest in a child was strongly discouraged, because sexual excitement of any kind was thought to damage the health and discourage the maturation of a child. In the past, parents have resorted to extreme measures to prevent children from masturbating, such as tying them down to keep from touching themselves or even making permanent surgical changes to their genitals. While these extreme measures have for the most part been abandoned in today's society, the attitude that the idea of sex is harmful to children still endures.
