Girls need to be gotten when young then trained like someone would train a pet. Girls are like animals. Give them too much freedom and they'll be feral and do whatever they want which we can all observe in modern society. They need to be trained when young with a carrot and stick approach, made dependent, and then brought under control. 12-17 should be legal, but my preference is 14-15 years old. 13 under the right circumstances.
You can't tame an older girl. Should be obvious because even Miley Cyrus sung about how sluts can't be tamed and can't be saved. No point in loving a filthy slut! If you listen to the lyrics, Miley Cyrus perfectly describes all the slut foids 18+.
