Topic: Is horizontal or vertical diphallism superior?

When you have two functioning penises, is it better to have them side by side, or arranged vertically?

Personally I think Horizontal is superior because it has an easier time being stuffed into two vaginas at once. What does Vertical have over that? An easier time being double-stuffed into one vagina or anus? Just rotate her. Or yourself.

If it's vertical arranged, you could put both penises into both holes at once, or into a single hole of two individuals who are either fucking as well, or making out.
Ergo, imo, vertical is superior.
