We took a very different approach in my house. My daughter sees, by example, how my husband treats me: with love, tenderness, loyalty, honor, and respect. I, as her mother, instruct her on how a woman should be treated.
From a very early age, she has learned how a loving man should behave. She has learned that if he says ugly things to her, treats her disrepectfully, pushes her for sex, he's not for her. She also knows exactly what to do if a man ever raises a hand to her: kick him to the curb. She has also learned to be upfront, to not toy with the emotions of those she loves.
I have often praised my husband's judgment infront of her, and informed her to trust Dad's opinion.
To ensure my sons are not part of the problem, they have received similar instructions.
I didn't have to beat my children over the head with rules: I used a lot of examples as (forgive the term) "teaching moments." It's easy nowadays to point of the foolishness and misery that comes from sex outside of marriage and God's law; they see first hand the love and joy that comes from my husband and I building a life together inside of God's law.
And if that doesn't work, we have an arsenal, a plot of land, and shovels as a back up.
That is certainly true. I make a point of showing my children examples of how what my husband and I (and our faith) tell them is wrong is also stupid and productive of bad outcomes.
I take a special pleasure in ruining popular songs for my daughters by providing real-world translations:
"Chasing the drama relationship" equals "38 and still single."
He means, "I'm a loser who will never commit, but have sex with me anyway."
"She sees 'sparks fly,' you see 'dishes, laundry, and diapers.' "
"No ring? She gets pregnant and he walks away. Now that's true love!"
