> An exception is made in the case of consensual sex with someone under 16 "when the other party is of a similar age or stage of development and maturity"
Also, what is wrong with teenagers having consentual sex with adults? That might not be moral by your standards, but why do you try to push your standards to others? You don't want to do it with teenager, it's ok, don't do it. I don't want to do it with the same sex, but I don't say that's immoral or that it should be forbidden.
Don't pretend that teenagers are somehow "not ready" for sex because you think that it's too early. Every living creature on this planet can have sex the same moment when it's physically ready. The nature sorted that out already, and there's no teed to put some arbitrary constrains over that.
