With regard to sex, it's been rightly said that our problem is not that we think about it too much, but that we think about it too little.
If we take time to think clearly and honestly about it, we can better understand what is right and wrong, moral and immoral.
Living in accord with the origin, design, and purpose of sex makes our lives (married or single) happier and more prosperous.
We do not thrive when we are selfish addicts -- when we love things and use people.
Rather, we thrive when we are generous and properly ordered -- when we use things and love people.
