The cock on the futa is way too big, which makes it super unrealistic, which then crosses into the uncanny valley, which essentially kills any eroticism. Bigger is not always better.
If you guys like HUGE unrealistic super sized futa dicks, can you explain why? I've tried for years to understand it, but it's not as arousing as cocks that have more realistic sizes (8-9 inches, 10 inch tops).
EDIT: If the super huge unrealistic dick turns you on, keep it. But it never hurts to try and make it smaller, do another render and compare, which do you like more, the realistic size or unrealistic? You might find the smaller size is actually more of a turn on (still big, but like 8-10 inches tops)
