Please do not think that adults can have sex with 15-year-olds in LA without facing consequences for their actions. As another poster pointed out, there are laws prohibiting sex with anyone under the age of 17, if the perpetrator is 2 years+ older than the victim.
RS 14:80. 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.
