The law criminalises people who have sex with under-16-year-olds. So, if an 18-year-old is having consensual sex with a 15-year-old, the 18-year-old is guilty of an offence and the 15-year-old is the victim.
Is it okay for a 15 year old to date a 18 year old?
In a Nutshell: Sex between an 18 year-old and a 15 year-old is illegal in California, meaning any touching of “private parts” of either, even with consent of both parties (and perhaps even the parents of each teenager) is illegal in California because the age of consent is 18.
Can a 16 year old date a 18 year old in Australia?
The age of consent is the age at which the law says a person can agree to sexual activity. If you are 16 years old and above, you can legally have sex (or do another sexual activity) with another person who is 16 years or older as long as you both agree to it.
Is posing as a minor illegal?
Yes, you can. The prosecution of those looking to have sex with a minor over the internet has exploded in recent years. These cases are easy to prosecute: police officers pose as underage minors (or the minors parents) and get people to make incriminating statements.
