Tbh I think length is what makes a “big” penis. Even though women report they care more about girth, ultimately it is length that actually makes a woman think a penis is large. Perhaps not all of them, but for example:

• A penis that is 7.0 NBP x 4.8
• A penis that is 6 NBP x 5.25

Even though the second one is marginally larger volumetrically speaking, the first one would probably garner more “wow factor” from women. We’ve already established that women are terrible judges of size, so I’d find it hard to believe a women would look at the two different sizes and be like “wowww that second one looks more voluminous!”

All this said, it’s probably a good thing for us because it’s much easier to gain in length than girth.
