A statutory rape is different from a rape itself. A statutory rape means having sexual relationship with a person who is neither a child nor has reached the statutory age. In the case of a statutory rape, it does not matter if whether or not the female has consented to the sexual action. There is a consent age which varies from state to state. The consent age is also known as the legal age to have sexual intercourse. It is mainly only applicable in case of females. A female above the age of 14 is not considered a child but has still not reached the legal consent age. The legal consent age in most states is 17 or 18. The state law has strict laws against statutory rape but in most cases it is not reported.
The whole idea that copulation under a certain age is automatically rape is relatively recent.
