Paraphilias are atypical sexual interests or behaviors that may involve intense sexual arousal from specific objects, situations, or individuals. These interests can include a wide range of activities, such as fetishism, where a person is attracted to non-living objects, or voyeurism, which involves gaining pleasure from watching others engage in sexual activities. While some paraphilias are considered harmless and consensual, others may lead to legal or ethical issues, especially if they involve non-consenting individuals. Mental health professionals often assess paraphilias to determine if they cause distress or impairment in a person's life, guiding appropriate treatment if necessary.
