Okay, I've never heard about you so I am unbiased and I am not a hater.
Having said that I must now say that you did push that ruler down incredibly deep and it looks like taking that photo might have been painful(which would account for the shakiness)
Anyway, from the photos I'd say that it looks like it's really between 7.5 or 7.75. At any rate it's nothing to be ashamed of. You have an attractive dick and it looks plenty thick too.
No hate intended in any of the comments I just made, just from one man to another.
BTW, the best way to measure the length of an erect penis is to simply lay the ruler across the top while standing up, that's the real pudding.
