This likely underrepresentation may also be attributable to a "societal tendency to dismiss the negative impact of sexual relationships between young boys and adult women". Michele Elliott has done extensive research on child sexual abuse committed by females, publishing the book Female Sexual Abuse of Children: The Last Taboo in an attempt to challenge the gender-biased discourse surrounding sex crimes. John Hunsley states that physiological limitations in the study of female sexuality must also be acknowledged when considering research on paraphilias. He states that while a mans sexual arousal can be directly measured from his erection (see penile plethysmograph), a womans sexual arousal cannot be measured as clearly (see vaginal photoplethysmograph), and therefore research concerning female sexuality is rarely as conclusive as research on men. Legal issues
In the United States, since 1990 a significant number of states have passed sexually violent predator laws. Following a series of landmark cases in the Supreme Court of the United States, persons diagnosed with paraphilias, particularly pedophilia (Kansas v. Hendricks, 1997) and exhibitionism (Kansas v. Crane, 2002), with a history of anti-social behavior and related criminal history (that includes at a determination of at least "some lack-of-control" by the person), can be held indefinitely in civil confinement under various state legislation generically known as sexually violent predator laws and the federal Adam Walsh Act (United States v. Comstock, 2010). See also

Paraphilia (previously known as sexual perversion and sexual deviation) is the experience of intense sexual arousal to atypical objects, situations, fantasies, behaviors, or individuals. It has also been defined as sexual interest in anything other than a consenting human partner.There is no scientific consensus for any precise border between unusual sexual interests and paraphilic ones. There is debate over which, if any, of the paraphilias should be listed in diagnostic manuals, such as the Diagnostic and Statistical Manual of Mental Disorders (DSM) or the International Classification of Diseases (ICD). The number and taxonomy of paraphilia is under debate; one source lists as many as 549 types of paraphilia. The DSM-5 has specific listings for eight paraphilic disorders. Several sub-classifications of the paraphilias have been proposed, and some argue that a fully dimensional, spectrum or complaint-oriented approach would better reflect the evidence. Terminology
History
Many terms have been used to describe atypical sexual interests, and there remains debate regarding technical accuracy and perceptions of stigma. Sexologist John Money popularized the term paraphilia as a non-pejorative designation for unusual sexual interests. Money described paraphilia as "a sexuoerotic embellishment of, or alternative to the official, ideological norm." Psychiatrist Glen Gabbard writes that despite efforts by Stekel and Money, "the term paraphilia remains pejorative in most circumstances. "Coinage of the term paraphilia (paraphilie) has been credited to Friedrich Salomon Krauss in 1903 and it was used with some regularity by Wilhelm Stekel in the 1920s. The term comes from the Greek παρά (para) "beside" and φιλία (-philia) "friendship, love".
