Interesting discussion But don't forget, most of the "oversized" and "armlong" cocks are used in fictional monster / creature 3D work. Of course, if I would ever make a realistic 3D porn, then I would take a look and tell to my self. Com on …. that looks unrealistic and silly. And to be honest, a big creature with a small or midsized prick isn't that scary at all. Since most of the "Big Ones" are harmless, they need a weapon to scare the girls a bit ...
For me, a lot of the 3DX work out there is too big. That's bad, because a lot of that stuff is really good, but those unrealistically tits or armlong cocks ruin it for me. I know, a lot people like it, but I'm a fan of realistic proportions, like the work of HZR or eclesi4stik.
As for cock size? dunno, can't remember seeing anything and thinking "thats just silly"
For my taste the last Mod from DarkCreatureZ for example or some of Zzomps pictures. Great work, but those armlong cocks ruin it.
