I think the cocks in a lot of 3D porn kinda suck. I think the size and shapes most commonly seen is just -too- uniform across the field. this is a common issue with 2D as well of course but its worse in 3D, everyone has The Same 11"x7.5" dong. 2D theres a lot of true Cock Perverts out there who clearly have attractions towards particular attributes of or kinds of penises [ex: myself and my personal fixation on girth over length] but a lotta 3D feels like they picked up the first dong model they could find and called it a day. Maybe they at least pick up one of the better ones like rigid3D's but a lotta folks just find some musty dusty jpeg lookin ass dick model and its like man couldnt you have found something a bit more fun.

You see more variety in furry circles [unsurprisingly] but it feels shockingly niche compared to other mediums
