... Statutory rape laws?
https://en.m.wikipedia.org/wiki/Statutory_rape
Statutory rape is sexual activity in which one of the individuals is below the age required to legally consent to the behavior in some common law jurisdictions. Although it usually refers to adults engaging in sex with minors under the age of consent, it is a generic term, and very few jurisdictions use the actual term statutory rape in the language of statutes.
Different jurisdictions use many different statutory terms for the crime, such as sexual assault (SA), rape of a child (ROAC),corruption of a minor (COAM), unlawful sex with a minor(USWAM), carnal knowledge of a minor (CKOAM), unlawful carnal knowledge (UCK), sexual battery or simply carnal knowledge.
In statutory rape, overt force or threat is usually not present. Statutory rape laws presume coercion, because a minor or mentally handicapped adult is legally incapable of giving consent to the act.
The term statutory rape generally refers to sex between an adult and a sexually mature minor past the age of puberty. Sexual relations with a prepubescent child, generically called child sexual abuse or molestation, is typically treated as a more serious crime.
(snip)
Statutory rape laws are based on the premise that an individual is legally incapable of consenting to sexual intercourse until that person reaches a certain age. The law mandates that even if he or she willingly engages in sexual intercourse, the sex is not consensual.
