The issue here is that most countries define the age of consent differently. I think we can agree that when a 16 year old agrees to sexual contact with another 16 year old, the dynamic is different than if they agree to it with a 40 year old. Absolutely. But that does not mean that the 16 year old doesnt understand what they are doing.
Imported US culture (movies, TV etc) has successfully planted the idea in a lot of people that teenagers under 18 are “essentially the same as little children”. So no one cares about technicalities.
