The DSM-IV recognizes two areas of sexuality that may require treatment. The first area is referred to as the paraphilias, which mean that the choice of sexual object, style of sexual satisfaction, or location of the activity is recognized as unusual by our society as a group. The second area is called sexual dysfunctions, which means that you don't enjoy sex enough or you aren't very good at it. Our authors gave sexual abuse its own section, although it is called pedophilia and is actually listed as a paraphilia. The only paraphilia besides pedophilia that is actually dangerous is sexual sadism.

These persons, mostly men, feel that they are above the law and definitely smarter than law enforcement authorities.
