You'd have to ask a lawyer. I don't know of any civil actions that could be taken in a case like this.

Statutory rape. The phrase statutory rape is a term used in some legal jurisdictions to describe consensual sexual relations that take place when an individual (regardless of gender) has sexual relations with an individual not old enough to legally consent to the behavior. However, in most states age of consent IS 16, so it depends on which state the female lives in. Each US state has its own age of consent. Currently state laws set the age of consent at 16, 17 or 18. The most common age is 16 (more than half of the states have this age limit), however the five most populous states all have a higher age of consent (California-18, Texas-17, New York-17, Florida-18 and Illinois-17). Age of consent 16: Alabama Alaska Arkansas Connecticut District of Columbia Georgia Hawaii Indiana Iowa Kansas Kentucky Maine Maryland Massachusetts Michigan Minnesota Mississippi Montana Nevada New Hampshire New Jersey New Mexico North Carolina Ohio Oklahoma Pennsylvania Rhode Island South Carolina South Dakota Vermont Washington West Virginia Age of consent 17: Colorado Illinois Louisiana Missouri Nebraska New York Texas Age of consent 18: Arizona California Delaware Florida Idaho North Dakota Oregon Tennessee Utah Virginia Wisconsin Wyoming SOURCE for "ages of consent" portion: http://en.wikipedia.org/wiki/Ages_of_consent_in_North_America
