Anyway, what does consent have to do with it. Consent, as I get the thinking, only applies to virginity. You can't tell when a boy becomes sexually active; more importantly, neither can he get pregnant!
I was racing power boats when I was fifteen, my capacity to make decisions, all kinds, was pretty well developed. No young, pretty teacher would be outside my still-developing mental capacity! Maybe I'm an exception, but I don't think so. I used to go to a lot of airplane soaring events. They give full-sized gliders to young men and women at age 14 to fly solo!
I rest my admittedly non-professional case.
Male or female particularly in the teen aged years do not have, by development, their full mental capacity.
You are the one who brought up lowering the age of consent. My point is that it ought to be raised. The brain development of a teen ager is sufficiently deficient to be able to give adult consent.
Additionally you look back on your teen aged self and think you were smarter and more mature than you were
