Paraphilias are sexual desires or activities that lie outside the cultural norm, and under some conditions are considered mental disorders. Some paraphilias have been (and are) considered to be sex crimes in some jurisdictions. At one time homosexuality was considered to be a paraphilia, but currently it is usually not reckoned among them.
Similarly, consensual sadomasochism, exhibitionism, voyeurism and non-psychotic forms of fetishism, urophilia and coprofilia are increasingly becoming culturally acceptable forms of sexuality. Professional treatmeant is usually indicated only when such conditions lead to involvement of non-consenting sexual partners, or are clearly damaging to the physical or mental well-being of the paraphiliac.
