Scientifically speaking why do men, on average, find women with large breasts, wide hips, nice ass and thin waist the most attractive? What is it about the hour glass figure? And to the inevitable outliers who prefer flat chest/asslet/fatter women fuck off with your opinion I am asking why on average men prefer hourglass figures as a whole from a scientific standpoint not your personal preference.

Do larger breasts have anything to do with milk production for instance? What exactly about the hour glass figure signifies fertility? What is the logic behind it that makes the peepee stand up?
