As 16 is the legal age of consent, meaning you can legally have sex with a person at that age, it is illegal for anyone above the age of 16 to have sex with a person below the age of 16. Therefore, when you sleep with a 15 year old (or younger), you will get 20 years in prison. 15 (years old) will get you 20 (years in prison).
