**Core Concept**
Sexual masochism is a paraphilic disorder characterized by intense and recurrent sexual arousal from fantasies, urges, or behaviors involving receiving pain or humiliation. This condition is distinct from sadism, where an individual derives pleasure from inflicting pain on others.

**Why the Correct Answer is Right**
Sexual masochism is often associated with the brain's reward system, where the release of neurotransmitters such as dopamine and serotonin plays a crucial role in modulating the individual's response to pain and humiliation. This can be linked to the anterior cingulate cortex, a region involved in emotional processing and pain perception. In some cases, individuals with sexual masochism may engage in self-harm or seek out partners who can inflict pain as a means of achieving arousal.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is likely incorrect because it would imply a different paraphilic disorder, such as fetishism or transvestism, which involve non-painful or non-humiliating stimuli.
**Option B:** This option is incorrect because it would imply a psychological or psychiatric condition unrelated to sexual behavior, such as an eating disorder or anxiety disorder.
**Option C:** This option is incorrect because it would imply a condition involving a lack of sexual desire or arousal, rather than an excessive or distorted response to pain or humiliation.

**Clinical Pearl / High-Yield Fact**
Individuals with sexual masochism often exhibit a pattern of self-destructive behavior, which can be a concern for clinicians assessing the risk of self-harm or suicidal behavior in these patients.

**Correct Answer:** D.
