What legal term describes sexual relationships between a minor and an adult when the minor is not married to the adult?

The term that most accurately describes the situation of sexual relationships between a minor and an adult, where the minor is not married to the adult, is statutory rape. This term specifically refers to sexual intercourse with a minor who, by law, cannot consent to such an act due to their age. Statutory rape laws exist to protect minors from exploitation and abuse by older individuals, recognizing that they are not capable of giving legal consent, regardless of their actual understanding or maturity.

While "unlawful sexual intercourse" is a broader term that can encompass various illegal sexual acts, including those with minors, statutory rape is more precise in its definition and application to cases explicitly involving minors and adults. Understanding these distinctions is crucial in legal contexts, as the specific term used can carry significant implications regarding prosecution, penalties, and related legal considerations.

The other terms provided, such as child molestation and sexual exploitation, refer to distinct types of offenses and behaviors, which do not encompass the exact legal definition applicable to consensual relationships as deemed by the law concerning age.
