Here is what the Arizona Revised Statutes have to say about the matter:
13-1405. Sexual conduct with a minor; classifications
A. A person commits sexual conduct with a minor by intentionally or knowingly engaging in sexual intercourse or oral sexual contact with any person who is under eighteen years of age.
B. Sexual conduct with a minor who is under fifteen years of age is a class 2 felony and is punishable pursuant to section 13-604.01. Sexual conduct with a minor who is at least fifteen years of age is a class 6 felony. Sexual conduct with a minor who is at least fifteen years of age is a class 2 felony if the person is the minor's parent, stepparent, adoptive parent, legal guardian or foster parent and the convicted person is not eligible for suspension of sentence, probation, pardon or release from confinement on any basis except as specifically authorized by section 31-233, subsection A or B until the sentence imposed has been served or commuted.
A. It is a defense to a prosecution pursuant to sections 13-1404 and 13-1405 involving a minor, if the act was done in furtherance of lawful medical practice.
B. It is a defense to a prosecution pursuant to sections 13-1404 and 13-1405 in which the victim's lack of consent is based on incapacity to consent because the victim was fifteen, sixteen or seventeen years of age, if at the time the defendant engaged in the conduct constituting the offense the defendant did not know and could not reasonably have known the age of the victim.
C. It is a defense to a prosecution pursuant to section 13-1402, 13-1404, 13-1405 or 13-1406, if the act was done by a duly licensed physician or registered nurse or a person acting under his or her direction, or any other person who renders emergency care at the scene of an emergency occurrence, and consisted of administering a recognized and lawful form of treatment which was reasonably adapted to promoting the physical or mental health of the patient and the treatment was administered in an emergency when the duly licensed physician or registered nurse or a person acting under his or her direction, or any other person rendering emergency care at the scene of an emergency occurrence, reasonably believed that no one competent to consent could be consulted and that a reasonable person, wishing to safeguard the welfare of the patient, would consent.
D. It is a defense to a prosecution pursuant to section 13-1404, 13-1405 or 13-1406 that the person was the spouse of the other person at the time of commission of the act. It is not a defense to a prosecution pursuant to section 13-1406.01 that the defendant was the spouse of the victim at the time of commission of the act.
E. It is a defense to prosecution pursuant to section 13-1404 or 13-1410 that the defendant was not motivated by a sexual interest. It is a defense to prosecution pursuant to section 13-1404 involving a victim under fifteen years of age that the defendant was not motivated by a sexual interest.
F. It is a defense to prosecution pursuant to section 13-1405 if the victim is of the age of fifteen, sixteen or seventeen, the defendant is less than nineteen years of age or attending high school and is no more than twenty-four months older than the victim and the conduct is consensual.
Essentially it says the same and means the same thing as the Tennessee Code Annotated but takes two separate codes to address the age difference between the victim and offender. My opinion is that the Tennessee Code Annotated is much more direct than the Arizona Revised Statute. Also, the Arizona Revised Statute definations of indecency are so broad that specific exemptions had to be made so that pediatricians and physicians can perform their medical prodecures without fear of prosecution. Tennessee's legislators simply assumed that a reasonable person would understand that the criminal law should only be applied when appropriate and that such decisions should be left up to the county or state prosecutor, the state medical board and the grand jury.
