Well, it is a well written article and does delve into the why's of size hang-ups.
BUT...Let me tell you about my particular case:

When I was just a young lad, around 10 or 11, I suffered an injury to my left testicle. (Went off a curb on a bike that was too big for me and crashed down on the center bar, crushing my left nut, yeah, ouch) I was in so much pain that my Dad took me to the Dr. who said, "He's young, and he still has a good testicle and will out grow this."
Stupid Fookin Dr. But you have to realize that this was in the early 50's.
Anyway, as I went through puberty, I didn't develop to my potential as far as penis size.
My Dad was over 8" and both my sons are huge. I always felt so cheated.
I never had any complaints about my size, at least not to my face and I was with a lot of women before marriage. But during high school I would always wait until everyone was done showering before I would undress. Yeah, late to a lot of classes.
My little flacid hang was no more than a button and my erect length was just 4 3/4".
In the Army, you are forced to shower with everyone and I was teased and called, "Needle Dick the Bug Fucker" this hurt deeply and I wound up in a lot of fights.

In 2002, I discovered PE, and the Site I am at now, was talking about testosterone levels and how it related to penis development. My Dr. did a blood test for testosterone and found that I was very low. He started me on Androgel and eventually injections on a 21 day cycle. This seemed to kick start my gains, even though I had seen around 1/2" in length and 1/4" in girth, from around 3-4 months of manual exercises. (While I was at a pay site)
Now, with my hormone levels in balance, (even though my left nut is smaller than my right and the left nut is usually the bigger of the two and hangs lower, I have increased it's size by ball sack stretching and two stage pumping,) my gains have been amazing. But I also dedicated myself to growing a bigger dick and have worked hard.
Starting stats;
BPEL 4 3/4"
EGMS 4 1/4"
Now.....After over 5 years of doing the rub and tug;
BPEL 8 1/2"
EGMS 6 1/2" *

*BPEL, (Bone pressed erect length)
EGMS, (Erect girth mid-shaft.)
I don't know if the gains would have come without the testosterone, but this is my story. JP
