Which of the following would NOT classify as sexual acts in public?

Engaging in sexual acts in a private residence would not classify as a public sexual act because the scenario takes place in a private setting, where individuals typically have a reasonable expectation of privacy. Public sexual acts, on the other hand, generally involve behaviors that occur in locations accessible to the general public or where the public can readily observe the actions. Therefore, the other options pertain to behaviors that are overtly public in nature — such as nudity in a public space, indecent fondling visible to others, and sexual intercourse occurring in a public restroom, all of which can lead to public indecency charges due to their visibility and context.
