Back when I was in undergrad, I hooked up with a guy who was about 2.5-3 cut. It was really sad. I never said anything about it, but it was incredibly hard to suck something that small. I could never tell whether it was erect or not. Then he asked me if he could fuck me. I looked at him like he was insane. I don't even think he could slide that thing into a loose vagina. Nevertheless, he kept begging and pleading so I went ahead and let him. I told him I'd need lots of lube as I'm very tight, but he claimed he wouldn't need it. I never felt ANYTHING go inside my ass, but I did feel some light pressure on my sphincter. He said he didn't want to cum inside me (even though he never got in there) and proceeded to jerk off with his thumb and index finger until he cummed on my face. Afterwards, he asked me if I liked being fucked by him....I just humored him and said it was amazing.
As for the biggest...I'm pretty sure the biggest I've had was 9 cut and fairly thick. Nothing bigger than that, though. Aside from black men, I don't think the American South produces a lot of mammoth cock - at least that's been my experience.
