It is important to understand the differences between pedophiles and molesters. Pedophilia, which is a psychological disorder, is a distinct sexual preference for pre-pubescent children. The Diagnostic and Statistical Manual of Mental Disorders (DSM 111-R), which is published by the American Psychological Association, supplies this definition of pedophilia: recurrent, intense, sexual urges and sexual arousing fantasies of at least six months duration involving sexual activity with a pre-pubescent child (DSM, V.3, 1987). Generally, this means the target of the fantasy will typically be less than 12 years old. Notice the definition does not require the person to actually engage in a sexual act. Pedophilia is a psychological disorder that does not require, and usually does not involve, a criminal act. The pedophile might keep his desires a secret. He may never go public or share his fantasies with anyone. At times, they will even marry a single mother to gain or continue access to her children. Pedophiles can be very determined and single-minded in their efforts to stay close to children. Maintaining access to children at all costs is one of the defining trademarks of pedophilia, which will be discussed later. Child molesters, however, can have many different motivations for their crimes. And those motives, surprisingly, are often not of a sexual origin.
