OTOH,although it's not good for a female teacher to be with a male student I don't see how the student is damaged in any substantial way.
Depending on the age difference and the power difference, people who study adult-to-child sex abuse of boys have found that some boys are gravely harmed by statutory rape. A child cannot give consent because of an immature mind. The targeted male child experiences coercion, seduction and a sense of being overpowered by a woman. Especially if social media leaks get involved, the teasing, bullying or shunning that goes on during or afterward with the other kids or their parents can be very damaging.
They are damaged by it. It shapes their future experiences and views about women.
Regardless its an adult in charge over a minor. The adult knows what they are doing. They are using a minor to satisfy their sexual urges. Further it destroys a marriage when the adult female is married.
So regardless if you can personally grasp and understand the law, it doesnt matter if the minor is willing or not. When has that reason ever saved an adult male from consequences? Many girls are happy for the attention and fun from an older male in a position of power. The girls “are in love” often. Why aren’t the men saved by “well they weren’t damaged, they wanted to be with the guy” argument?
The reason is it doesnt matter. Male and female adults know what they are doing, it doesn’t matter if the minor consents because they can’t give consent and ifurther its immaterial to the laws on the books regarding sex with minors. And then also tack on they are in positions of power over these minors so theres a power element there.
