>>59113825It's not about the size of the dick, it's about the degree to which they align with the Big Futa Energy. Here, I've make a shitty chart to demonstrate.
Fauna has too much Mommy energy to hit the true Big Futa Energy side, but at the same time she's occasionally aggressive enough to qualify under a broadened umbrella. Mommy type characters are often depicted as futa anyways, but in that case it's usually more about the dichotomy between the futa and their normal behavior than the dick fitting them perfectly. Anyone in any quadrant could easily be depicted as futa, but in my opinion only those falling squarely into the top left corner can be truly said to ooze futa energy.
