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)
