I'm relatively certain that classical statues have penises that are much smaller than average, no? Like, often 1-2 inches on a life-size adult statue. It seems counter intuitive to me that classical nude sculptures would have unusually small penises. I've always wondered and it's never been talked about in the museum tours/classes I've taken. Google didn't help much either.

Examples of what I'm talking about:

Apollo Belvedere

Farnese Herakles

Laocoon and His Sons

I really do mean this as a genuine question, I'm not trying to be a jerk. I'm just curious... Today we think of penises as being symbols of masculinity and whatnot. I'm wondering what the different... Did people idealize having a small penis? Or would giving them larger penises have been considered crude? Are their any theories?
