Be careful if sex is involved.. .
According to Article 130 (Sexual Offenses) of the New York Penal Code, if the perpetrator is over 21 years old and the victim is under 17, this is known as third degree rape; if the perpetrator is 18 or older and the victim is under 15, then this is second degree rape; and, if the victim is younger than 11 years of age, then first degree rape has been committed.
