§ 18.2-63. Carnal knowledge of child between thirteen and fifteen years of age.
If any person carnally knows, without the use of force, a child thirteen years of age or older but under fifteen years of age, such person shall be guilty of a Class 4 felony.
However, if such child is thirteen years of age or older but under fifteen years of age and consents to sexual intercourse and the accused is a minor and such consenting child is three years or more the accused’s junior, the accused shall be guilty of a Class 6 felony. If such consenting child is less than three years the accused’s junior, the accused shall be guilty of a Class 4 misdemeanor.
In calculating whether such child is three years or more a junior of the accused minor, the actual dates of birth of the child and the accused, respectively, shall be used.
For the purposes of this section, (i) a child under the age of thirteen years shall not be considered a consenting child and (ii) “carnal knowledge” includes the acts of sexual intercourse, cunnilingus, fellatio, anallingus, anal intercourse, and animate and inanimate object sexual penetration.
§ 18.2-66. Effect of subsequent marriage to child over fourteen years of age.
If the carnal knowledge is with the consent of the child and such child is fourteen years of age or older, the subsequent marriage of the parties may be pleaded to any indictment found against the accused. The court, upon proof of such marriage, and that the parties are living together as husband and wife, and that the accused has properly provided for, supported, and maintained and is at the time properly providing, supporting and maintaining the spouse and the issue of such marriage, if any, shall continue the case from time to time and from term to term, until the spouse reaches the age of
sixteen years. Thereupon the court shall dismiss the indictment already found against the accused for the aforesaid offense. However, if the accused deserts such spouse before the spouse reaches the age of sixteen without just
cause, any indictment found against the accused for such offense shall be tried without regard to the number of times the case has been continued, and whether such continuance is entered upon the order book.
