What crime has John committed if he touches another person's genitals without consent for his own sexual gratification?

The act of touching another person's genitals without their consent for the purpose of sexual gratification falls under the category of indecent assault. This crime typically involves unwanted sexual contact that is inappropriate and offensive to the victim. Indecent assault does not require penetration or additional sexual acts; the key element is the non-consensual touching that is sexual in nature.

In this scenario, John's actions constitute indecent assault because they violate the victim's boundaries and involve an inappropriate sexual encounter without consent. It illustrates a clear disregard for the autonomy and safety of the other person, which is a fundamental aspect of this offense.

In contrast, other options refer to different types of offenses: indecent exposure typically involves a person exposing their genitals to others in a public setting; sexual battery generally entails legally defined physical sexual contact that can include penetration; and sexual harassment usually involves inappropriate behavior or comments of a sexual nature that create a hostile environment but not necessarily touching. Thus, the specific nature of John's actions aligns most closely with indecent assault.
