What constitutes sexual penetration according to legal definitions?

Sexual penetration, as defined in legal terms, typically encompasses any form of contact between sex organs and any part of the body. This broad definition is intended to cover various forms of sexual acts that may not fit neatly into more stringent or narrow definitions. The key aspect is the recognition that such contact constitutes a violation of personal autonomy and consent when it occurs without agreement from all involved parties.

Other options, while related to sexual offenses or crimes, do not specifically define sexual penetration. Touching or fondling for arousal relates more to sexual contact but does not imply penetration. Detaining another person without legal authority and secretly confining another person against their will are more associated with unlawful restraint or false imprisonment rather than sexual acts. Hence, the focus here is clearly on the understanding that sexual penetration must involve contact between sex organs, defining the act in a distinct and legally recognizable manner.
