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".
Prevention
Efforts to prevent bites include clearing clutter and the use of pesticides.OSHA recommends that workers take following measures to prevent spider bite:

Wear a long-sleeved shirt, hat, gloves, and boots when handling boxes, firewood, lumber, rocks, etc. Inspect and shake out clothing and shoes before getting dressed. Use insect repellents, such as DEET or Picaridin, on clothing and footwear. Management
Most spider bites are harmless, and require no specific treatment. Treatment of bites may depend on the type of spider; thus, capture of the spider—either alive, or in a well-preserved condition, is useful.Treatment of spider bites includes washing the wound with soap and water and ice to reduce inflammation. Analgesics and antihistamines may be used; however, antibiotics are not recommended unless there is also a bacterial infection present. Black widow post-envenomation treatment seeks to control resulting pain and nausea. In the case of bites by widow spiders, Australian funnel-web spiders, or Brazilian wandering spiders, medical attention should be sought immediately as in some cases the bites of these spiders develop into a medical emergency. Antivenom is available for severe widow and funnel-web envenomation. Necrosis
In almost all cases, recluse bites are self-limited and typically heal without any medical intervention. Recommendations to limit the extent of damage include elevation and immobilization of the affected limb, application of ice. Both local wound care, and tetanus prophylaxis, are simple standards. There is no established treatment for more extensive necrosis.
