The document summarizes research from a study of 50 female sex offenders and 36 controls. It describes the sample characteristics and finds that the women came from a variety of social and educational backgrounds. The study identified three types of female sex offenders: those with victims under 6 years old, those with adolescent victims in a "teacher/lover" role, and those who were initially coerced by a male partner. Across groups, common motivations included seeking control, intimacy or feelings of love. However, those initially coerced commonly reported negative feelings during the abuse. The study also examined the severity and types of abuse, including frequent insertion of objects and sadistic acts.
