Which disorder is marked by sexual arousal from the suffering of another person?

The disorder characterized by sexual arousal from the suffering of another person is indeed Sexual Sadism Disorder. This condition involves deriving sexual pleasure from inflicting pain, humiliation, or suffering on another individual. According to the DSM-5-TR, for a diagnosis of Sexual Sadism Disorder, the individual must have acted on these urges with a non-consenting partner or experience significant distress or impairment in their social, occupational, or other important areas of functioning due to these urges.

In contrast, Sexual Masochism Disorder involves sexual arousal from experiencing pain or humiliation, rather than inflicting it. Fetishistic Disorder involves sexual attraction to non-living objects or specific body parts, while Transvestic Disorder refers to sexual arousal from cross-dressing. Each of these disorders diverges from the core feature of Sexual Sadism Disorder, which is centric to the experience of arousal through the act of causing suffering.
