If a person (“A”), with any part of A's body or anything else, penetrates sexually to any extent, either intending to do so or reckless as to whether there is penetration, the vagina or anus of a child (“B”) who has not attained the age of 13 years, then A commits an offence, to be known as the offence of sexual assault on a young child by penetration.

Without prejudice to the generality of subsection (1), the reference in that subsection to penetration with any part of A's body is to be construed as including a reference to penetration with A's penis.
