In this era; maybe because of some social factors; younger folks have been seen to mature way faster than it had been. And not only that; they are also exposed quite early to sex-related matters.
So when the issue of consent comes into play, you would even discover that there is already a disagreement between the body morphology and the legal rights to get married.

Come to think of this; how do you explain a girl at the age of 9 having sexual urge? And if she has sex with an older guy; it would be termed statutory rape. Well, that's the flaw in the system.

Imagine a girl of 10 years having a boyfriend when she has not even passed her FSLC. And some laws are pegging age of consents at 18, lol. By 18, she must have even gotten tired of the whole stuff. How human.

Nicely written buddy
