Or for them to disagree with each other?
What universal age do you think everyone in all jurisdictions should be forced to accept, and how do you intend to enforce your moral superiority on them?
Legitimately, what age do you think should be the limit in the jurisdiction you live in? Before you make any compromises. How old?
Juries are supposed to use the very harsh letter of the law, no exceptions.
These laws are bad and should be reformulated to handle real life, which has corner cases (e.g. interstate romance between minors, what about it?) and where prosecution could cause more damage than it helps.

Everyone always hates thresholds. That's just a fact of life.
These laws are good. If you can't wait for someone to be legal, then you shouldn't be having sex with them in the first place. Find a different partner.

How about no. It's already incredibly difficult to convict someone of rape, because consent comes down to he-said / she-said. Keeping statutory rape on the books makes it much easier to convict people who went after children, at least.
PS, I am not a lawyer, or a child psychologist, and I highly doubt you are, either.
