What happens if a person under the age of consent rapes a person over the age of consent? (Ex: A 12 year old rapes an 18 year old.)

The law does not recognize the possibility of a 12 year old raping an 18 year old or older adult. The law requires that an 18 year old refuse or prevent a sexual act from occurring. Simply put, the law requires that the act be non-consensual.
