I'm naturally attracted to girls who have high standards (of chastity, morality, etc.). It makes them more precious to us guys. I tend to prefer girls who, knowingly or not, set an example or goal that I want to achieve as well.
Men really need some help, don't they? They need someone who will consistently motivate them and back them up.
When they are down (for whatever reason), someone who will comfort them. When they are cheerful and joyous, someone who will share in with their laughter. When they are heavily burdened, someone who will share it as they pour it all out. When they are discouraged, someone who will strengthen them. As they advance through life and the world, someone who stands by them, 'holding the sword,' yet at the same time, needs their protection (men have an instinctive desire to protect others, you know). That's the companion their hearts desire.
