What is the term used for the intentional exposure of a person's genitals for sexual arousal?

The term that accurately describes the intentional exposure of a person's genitals for sexual arousal is indecent exposure. This offense typically involves exposing oneself in a manner that is considered inappropriate in public or semi-public settings, with the intent to sexually arouse or gratify oneself or another person.

Indecent exposure is often defined by law as a crime because it disregards the societal standards of decency and can cause distress or alarm to others who witness the act. While public indecency also refers to inappropriate sexual behavior in public, it is a broader term that might include acts like masturbation or sexual acts rather than the specific act of exposing genitals.

Sexual assault refers to acts of sexual violence or coercion, and obscenity generally pertains to material that violates contemporary community standards regarding sexual content. Both of these terms involve different legal definitions and implications than indecent exposure, making the latter the precise answer to the question at hand.
