Go read the fucking tanner scale you retard. It has nothing to do with psychology, sexual maturity is a biological state of being. Sexual development stops, on average, when a female is 14.5 years old. God I have researched everything I talk about you are not going to find something that I am wrong on, you on the other hand are just talking out of your ass and acting superior when in reality you are just saying a bunch of bullshit you know nothing about. Uhm no, females hit peak fertility around 14.5 years old you dumbshit, they start to become less fertile already in their 20's.
