The legal definition of "age of consent" is:
Age of consent refers to the legally defined age at which a person is no longer required to obtain parental consent to get married. It also refers to the age at which a person is held to have the capacity to voluntarily agree to sexual intercourse. Sexual intercourse with a person under the age of consent may lead to criminal charges of statutory rape or sexual assault . . . .
Statutory rape is sex between an adult and a minor below the age of consent. Every state has a statutory rape law in some form. The age of consent varies from state to state, but is generally from 16 – 18 years of age. . . . Consent of the victim and belief that the victim is of the age of consent are usually considered immaterial.
