My theory is that it is part of a larger set of neotenic preferences shared by many males and reinforced by society, the underlying purpose of which is to exacerbate the dominance of males over females in all measurable quantities, probably either by sentiments of insecurity or jealousy. Except for the emphasis on large breasts, everything that our society and many a male (and female) say is ideally attractive about females points not to the image of an adult female, but a juvenile one. Boyish thinness, no body hair, shortness relative to males, docility and submissiveness, physical fragility, no body scent...it all points to a desire to control females. I find it sick, a perversion of sexuality, which emphasizes youth, power, suppleness, and vigor.
