if you think that anyone with a big dick is superior to anyone else then that means your perspective of life is very skewed and you're somewhere lost way out in left field...
i'll prove it to you right now... when you go check out for groceries, ask the person in front of you if you can cut in front of them because you have a big dick, when you go to your doctor's appointment, ask the check in person if you can cut to the front of the waiting room because you have a big dick, when you order you food at a resturaunt, ask the waiter for the big dick discount, and when you apply for a job, make sure you add "have 8 inch penis and very skilled at using it" under the the skills section of your resume.
when you've done all that, come back and let us know how superior a person with a big dick is.
