granting 7.5 BPL, your NBP is in the 6s. Danny is in the 8s NBP. There is a 2 inch difference, that's a lot of cock. I agree. What you are doing is comparing your BPL size to his visible length size (NBP), and concluding that he has to be more than an inch bigger than you... Well, he still is. If you were to appear on cam we'd comparing your NBP size his, as this is all you can see in porn, not your BP. We don't know how thick his pad, though I'd be surprised if it even reached a half an inch given his body type. His BP may be in the upper 8s somwhere.
Danny D doesn't tower over me, though he is longer.
I'm thicker. I don't even think he's 6.25 girthwise, but oh well.
