I got MOST of my pubescent penis growth in a three-month period. I remember when I was ten years old, measuring my penis at 4.5" BPenis EnlargementL, and over the summer, I measured it almost every day and by the time I started junior high school (three months later) it was at 6" BPenis EnlargementL. By the time I began Penis Enlargement at age 19, I had a 6.5" BPenis EnlargementL. Seems like all that measuring I did kept me erect longer, and I grew enormously at that stage, but then when I got content with my size and no longer measured, it simply stopped growing. I also did some weight cutting practices throughout high school,for sports, that likely had a negative effect on penis growth.
I wish I had been faithful about Penis Enlargement when I first found out about it at age 15. I had the knowledge, I was just not motivated enough to apply it! But I doubt ANY 15 year old is motivated enough to spend two hours every single day doing Penis Enlargement, or even one hour. I was a busy kid, and finding that amount of privacy would have been doable, but a pain in the ass.
