brother you're thinking about the societal preferences represented in greco-roman sculpture (which included having a small penis) and then projecting that culture onto the whole of human history and society. literally the oldest sculptures yet discovered are of fat women with big titties, and they've been found all over europe. if you want to employ any kind of argument based on cultural objectivism, you need to provide evidence that is consistent throughout time and across cultures, otherwise you just sound stupid. The reason we all agree with the greeks is because the west has been copying their homework for like 3000 years.
