Teacher and student made headlines.

health from sex depends purely on the age of the person you are having sex with

indoctrinates them into feeling shame

Law bans that too. 30% of sex offenders on the sex offender's list came on the list as children, some as young as 8.

This is an appeal to law fallacy.

did 12 year olds become dumber in the past 300 years, or is law self contradicting?

Yeah, that's why the law exists. Because kids are very impressionable.

Even now, as an adult, I wish I had sex at an early age.

You don't know what the psychological effects would have been though. 

However, your argument was that adults know better so they get to decide

As soon as the term "rape" was brought up, we were discussing legal terms.

The law changed around the time we banned child labor and got stricter on child abuse. If we made a law to prevent exploitation, you should at least suspect there was a reason to go to that trouble

Adults (by majority) decided to make age of consent higher than 12.

No, but it's a significant factor.

Teachers especially have explicit and implicit authority over students.

And even if the odds of abuse are low, the risk is big enough that it's dangerous.

The law does not require anyone to shame statutory rape victims.

But an adult can easily shame them into having sex due to the power imbalance.

all actions are wrong as there is always power imbalance

There's degrees of power imbalance

It's nowhere near as strictly enforced on minors.

Do you think 12 year old young men are into grown teachers?

Is that creepy?

I'm just saying I knew of 12 year olds that were into their teachers. Maybe you can't relate to that, don't know nothing about that. 

At a certain point, Chesterton's fence applies. The law indicates that significant problems arose, at least for a large amount of people, to impose age restrictions.

I would weigh even a small risk of psychological trauma as more pressing than sexual pleasure.

Also, if you care about harm, you also have to care about harm which happens to pedophiles due to ban, which then makes your argument self defeating.

If you can get an erection you are ready for sex.

Like I said I knew 12 year olds that were into their teachers but the law is the law due to age which is the technicality I'm talking about which makes it criminal

technicality of age

When I was 12, all the guys in class were very much watching porn and talking about sex. They did make comments on teachers, but only on the hot ones tho.

So they were interested in porn and the hot teachers and not in each other.  Might explain why you turned trans.

Why's that?
