This is the male ideal of the era, bro. Look at some ancient Greek statues.
"Ancient Greek society and culture was highly male-oriented, in which the perfect male body was fetishised, and a large penis was not only undesirable, but considered downright disappointing and inferior.
The men depicted in the sculptures were all intended to be shown as smart, reliable, honest and of an admirable mind, and the small and flaccid penis was an integral part of this.
The ideal of man at that time was that his chief virtue was intellect, and that included abstinence. The penis was not then a symbol of power and strength, it was never seen as such in the cradle of democracy. Masculinity was the result of a well-honed mind, which was necessary for a man to be able to perform his duties properly: to carry on the bloodline, to keep his family together and to manage and discuss the affairs of the polis, the city-state.
Satyrs, fools and debauched people were usually depicted as half-animal, mongrel creatures, their megapenesis indicating their inability to control themselves or to think. The huge phallus was used to express their illiteracy and barbarism."
On this basis, it can also be objected that there are only women with perfect bodies in adult games.
