Some
are above average drivers. What is the tread wear rating on your tires? I know, do you?
Seriously though, on any bell curve about half of the people are above average. Some by a little, some by a lot. Penis size doesn't vary by much, though...just a few inches. There aren't any 3 footers out there. Length and girth are hard to measure, but volume is even harder, and that's what counts. And you're dealing with a muscle that changes volume depending on temperature and mood. Some goes with the ladies' muscles. It gets very complex very quickly.
You're stuck with what you've got so don't get hung (wink) up on it.
Instead, make it as perfect as it can be. Wash it. Trim it. Take Viagra if you need to. Use lotion to keep the skin soft if you need to. Accentuate the positive. Eliminate the negative.
...and wrap it in $100 bills.
