So the jeans you are wearing right now, assuming you bought them some time after the 1980s, have a very short rise, that is, the distance from the top of the waist band to the crotch. They are worn on your hips. If you tried to wear them any higher, you would probably talk in a high-pitched voice!
The natural waist is the place where men have worn their pants on since the invention of pants, their waist. And on men without "love handles" or "beer bellies", this is the narrowest part of their torso. When men's bellies started getting big a few years ago, men got into the habit of wearing their pants below the waist, and letting their fat belly hang over it. Look at yourself. If your natural waist is wider than your hips, then I can't really blame you for wearing your pants where you do.
To measure your natural waist, measure at your belly button. Your pants should be around your obliques, just below your belly button.
