It has long been politically correct to state that it's "not the size but the motion" that counts. Women have so long been under the thumb of religion and patriarchy and most women have learned that lying to "your man" is much more fruitful/profitable than denigrating him because of his lack of penis volume. And what good would discussing about penis size do anyway, it's not like a guy can change it. It is a done deal and it's simply not worth mentioning about it once in a couple context.
However, that being said, that point of view in no way dictates that biologically speaking, the penis size is unimportant. The vagina is an elastic structure and responds differently to various shapes and volumes. In addition, most studies indicate that the the penis size to total body ratio is a fairly good indicator of female sexual selection in nature. And Homo sapiens males are very well endowed indeed in this regard, favoring a view that in Homo sapiens females do exercise choice (evolutionary speaking).
