This is the exact legal mumbo jumbo . . . so afterwards, I'll translate (my uncle's a laywer).
PART V. OFFENSES AFFECTING THE PUBLIC MORALS
SUBPART A. OFFENSES AFFECTING SEXUAL
1. SEXUAL OFFENSES AFFECTING MINORS
§80. Felony carnal knowledge of a juvenile
A. Felony carnal knowledge of a juvenile is committed when:
(1) A person who is nineteen years of age or older has sexual intercourse, with consent, with a person who is twelve years of age or older but less than seventeen years of age, when the victim is not the spouse of the offender; or
(2) A person who is seventeen years of age or older has sexual intercourse, with consent, with a person who is twelve years of age or older but less than fifteen years of age, when the victim is not the spouse of the offender; or
(3) A person commits a second or subsequent offense of misdemeanor carnal knowledge of a juvenile, or a person who has been convicted one or more times of violating one or more crimes for which the offender is required to register as a sex offender under R.S. 15:542 commits a first offense of misdemeanor carnal knowledge of a juvenile.
B. As used in this Section, "sexual intercourse" means anal, oral, or vaginal sexual intercourse.
C. Lack of knowledge of the juvenile's age shall not be a defense. Emission is not necessary, and penetration, however slight, is sufficient to complete the crime.
D. Whoever commits the crime of felony carnal knowledge of a juvenile shall be fined not more than five thousand dollars, or imprisoned, with or without hard labor, for not more than ten years, or both, provided that the defendant shall not be eligible to have his conviction set aside or his prosecution dismissed in accordance with the provisions of Code of Criminal Procedure Article 893.
Amended by Acts 1977, No. 539, §1; Acts 1978, No. 757, §1; Acts 1990, No. 590, §1; Acts 1995, No. 241, §1; Acts 2001, No. 796, §1.
Okay, since you are both minors, it is not illegal in the eyes of the STATE and FEDERAL governments. I wouldn't go telling everyone about it . . . things get legally delicate when you're close to that magical age of consent. Please stay safe and enjoy yourselves!
