This thread is pure pseudo science. This is what happens when you try to project your fetish onto reality.
You overlooked many factors (some listed above) in evolution and only looked at ONE factor: penis size. This makes your argument very flawed.
"When they [females] chose sexual partners, considerations like wealth or social prestige had little to do, and it came from acknowledging her body’s desire in the face of true masculine strength." This statement can't be farther from the truth. The concept of the social dominance hierarchy is well supported by evolutionary scientists. Women tend to only reproduce with men that are higher up or across the social dominance hierarchy. This means social prestige, or status, is a huge factor in sexual selection. Wealth is another huge factor because it helps a woman support herself and her offspring, which increases her odds to pass on her genes. You said it yourself: sexual liberation occurred in western countries and women have mate choice. Guess who they demonstrate are attractive to them? Actors, millionaires, bosses, etc.
Women who reproduce with men of high socio-economic status are often in it for the money and lifestyle that such men can afford.
While hubby is at work, who knows how these women spend their time...
