ok. i know i am not allowed to post real stuff here, but the ancient greeks didn't make statures to depict sexiness. grrrrr
Then I suggest that they are perfectly normal. Maybe our idea of what's normal has been skewed by the modern porn industry.
I have another theory. They kept the penis small because it was an item that would easily break off. A practical consideration.
Oh come on, everyone knows greek statues was like porno for the ancient greeks. You know, you never see the backsides of those statues. Think they got tight, hard asses? Cause then the pieces would really start coming together.
No, i am fairly certain that is the answer. Last thing we need are sculptors in competion for the largest member.
I really have no idea, but it could be a matter of style. Someone once told me that large penises in Roman times were mocked. I have no idea if it's true. I was going to google but decided against it.
