I just looked it up for my country and the law is pretty complex but here's what I gathered

• 16 is the age of consent for sexual activity
• romeo-and-juliet laws for 14 and 15 year olds (up to 5 years their senior, imo this is too much)
• 16 and 17 year olds cannot consent if there is any power dynamic
• 18 is the age of consent for pornography

Imo it should probably be that the age of consent is 18, with 14-17 year olds under romeo-and-juliet laws (and maybe like 3 or 4 years their senior). High school is just such a different stage of life, and social acceptance into adulthood is at 18 anyway (though I personally didn't feel like an adult till I was 21)
