Ancient Greeks came to idealize small penises because many men were sore about having to grow up in pederastic relationships. amirite?

It's because most sculptors were men. who wanted to seem large by comparison.

Large penises can offen be found on men with mental instabilities, which explains my deppression.

Large penises were associated with people of low intelligence, which I can confirm is not true.

They also felt a huge schlong hanging on a statue detracted from the statue itself, I guess they realized what people would look at first...
