Just to offer even more fuel to the size inferno, if you think about how our genetics was carved out, over 250000 years or more, dick size would be a very small selective factor. There is nothing more vulnerable than a post partum female nursing a helpless infant. Thats why as Altered Ego put so clearly, she wants the whole package. Its in her genes. I think a female picks a male partner ( or better yet male partners who protect and nurture their female and baby have more off spring survive on the savanna) based on a whole host of qualities ( the whole package) because a baby born by a female with a wandering unprotective monster dicked male died a few days after childbirth. Her genetic material was then wiped from the earth forever. Its also why men are more drawn to the purely physical looks of a female. The survival of the baby is mostly dependent on the nurturing protective instinct of the male. The mother doesn't need to have the whole package, she just needs to be well put together. There you have it IMO. Women at one time needed a man who was there for the long haul. A prehistoric woman that had sex with an uncommitted big dick died out and so did her genes. Just my theory, shoot holes in it if you will.
