And yes it is true ladyboss. Procreation is a natural trait found in all living things.
We as men are naturally tuned to want to reproduce(hence why it feels so good). And when we do, we want someone who is healthy and in shape to produce our offspring. So that our bloodlines have the best chance of successfully growing. It's natural. Its instinct for a man to want to be with a pretty woman. Usually pretty equals in shape/healthy.
So to say that looks don't matter is silly. Looks don't matter in love and marriage, but love and marriage are human emotions and human laws. And I'm certain instinctual law trumps human emotion and human law
