Which of the following defines sexual masochism?

Sexual masochism is defined as the practice of becoming sexually aroused by the experience of psychological or physical suffering. This may involve receiving pain or humiliation in a consensual sexual context. The focus is on the individual who derives pleasure from being subjected to these experiences, rather than inflicting harm on others or engaging in behaviors that do not directly involve personal suffering.

In contrast, inflicting harm on others aligns more with sexual sadism, while observing others in sexual situations relates to voyeurism. Experiencing arousal from exposure pertains to exhibitionism. Thus, the essence of sexual masochism uniquely centers around an individual identifying pleasure in their own experiences of submission or suffering.
