It's an arbitrary "rule" that doesn't take into account the differences and uniqueness in our anatomies and so this makes it unscientific. Like I have said about Chris' own penis, it has a certain curvature that I have not seen in any other dick and the sheer size of it that's actually twice longer than the average one also makes the curvature more significant. Think about it, a curvature in a 4-inch penis is not gonna cover as much ground as one twice its length. Using a straight measuring device only measures the radius of the semicircle of the curved penis, which is significantly shorter than the actual length of it that does the actual PENETRATION in sex. The receiver doesn't feel 6.5 or 7 inches of the radius of Chris' dick (which is nonsensical) coming in but the full length of its flesh (not an imaginary line! Lol), which could be between 10 to 11 inches for him per comparison of ita visuals with my experience. That is what needs to be measured because THAT SENSATION is what really matters when we talk of penile length. There is actually not even any reason to measure it at all along with all the sexual competition and hierarchy the number connotes besides this singular literal significance. What will make the measurements scientific is to make them standard so you're not measuring one guy while he's standing up and using a ruler while you use a tape measure for another while he sits like Chris in the porn scene. That makes the whole comparison unfair and invalid. And that's unscientific
I actually found a lot of the comments here ridiculous and hilarious when they make such blanket statements that are rooted more on envy and ignorance than real knowledge. Like when they say "porn inches are not real inches." Lmao!!! How many of you have actually seen, touched, sucked and measured/estimated porn star dicks? I've actually had several and they include, like I said, other straight porn stars like Mark Ashley and Jack Lawrence whose cocks are very much within the ballpark stats of Chris'. As you can see from my examples, I know what 8.5 and 9 inch dicks look and feel like (actually up to 10 and 11 but I just didn't take those pics). So i have the unique perspective of estimating from their photos and videos and then being able to actually confirm my estimates in person. In reality, video has the tendency to give the illusion of making small objects appear larger and vice versa, so I was actually even nicely surprised/shocked at how their dicks were still larger than I expected, contrary to the common presumptions here. This wholesale generalization based on highly erroneous measurements is nothing but fallacious rationalization empowered by attempts to deal irrationally with inherent penis envy, which is part of human nature and unsurprising.
