Yes, for purposes of this law. See the text below. However, I find it odd that New York forbids you from buying cigarettes or drinking until you are 21, but sets the age of consent for sexual relations at 17 . . . .
"THE PEOPLE OF THE STATE OF NEW YORK, REPRESENTED IN SENATE AND ASSEMBLY, DO ENACT AS FOLLOWS: Section 1. Paragraph (f) of subdivision 3 of section 30.10 of the criminal procedure law, as separately amended by chapters 3 and 320 of the laws of 2006, is amended to read as follows: (f) For purposes of a prosecution involving a sexual offense as defined in article one hundred thirty of the penal law, other than a sexual offense delineated in paragraph (a) of subdivision two of this section, committed against a child less than eighteen years of age, ***** in the first, second or third degree as defined in sections 255.27, 255.26 and 255.25 of the penal law committed against a child less than eighteen years of age, or use of a child in a sexual performance as defined in section 263.05 of the penal law, the period of limitation shall not begin to run until the child has reached the age of [eighteen] TWENTY-THREE or the offense is reported to a law enforcement agency or statewide central register of child abuse and maltreatment, whichever occurs earlier."
