I've heard that it's slightly flattened at the poles...but not so that you'd really notice all that much.

Look, there are hundreds of thousands of stupid guys who think they're God's gift to women, just because they have a penis! That PROVES that people are capable of believing anything, regardless of evidence to the contrary.
