Putting things in a different perspective:
1 in 10 guys are 7x5.5.
Which means that 9 out of 10 guys are smaller than you. 1 out of those 10 guys are smaller than 4.7x4.
Half of the guys are going to be notably smaller than you at 6x5(barely).. But only one out of 100 guys are going to be notably bigger than you at 8x6
I know that our minds screw us over, but just look at the objective truth: a 7 inch dick is not rare, its not huge, but it is big.
Small: 5x4.
Average: 6x5
Big: 7x5.5
Porn and forums such as this one makes us believe that huge dicks aren't rare, but they are. And for every huge monster out there, there is another tiny one.
Male competetiveness drives us nuts, It's in our nature to never be satisfied with what we've got but I am 7x5.7 myself and have never been satisfied until i started doing research. Gave me a whole new perspective since the odds of having a 7x5.5+ are just as low as having a 5x4 inch dick.
