of childcare workers being charged with CSA. However, while CSA does occur, the response may be due to "moral panic" that is out of proportion with its actual frequency and over-reaction may have unintended consequences. Strict policies are being implemented not to protect children from a rare threat, but to protect workers from the accusation of CSA. The policies have created a split between childcare workers who continue to believe that behaviors involving nudity are a normal part of child development and those that advocate that children be closely supervised to prohibit such behavior. Between puberty and adulthood Contemporary issues In the latter part of the 20th century, sexual liberation probably arose in the context of a massive cultural explosion in the United States of America following the upheaval of the Second World War, and the vast quantity of audiovisual media distributed worldwide by the new electronic and information technology. Children are apt to gain access and be influenced by material, despite censorship and content-control software. Sex education The extent of sex education in public schools varies widely around the world, and within countries such as the United States where course content is determined by individual school districts.

The presenter, a physician, is relaxed about close examination and touching of relevant body parts, including genitals.

The causes of this premature sexualization that have been cited include portrayals in the media of sex and related issues, especially in media aimed at
