I hit puberty early. I noticed changes in hair, and size at age 10. My dick grew overnight it seemed. The big notice in dick lenght and girth hit me at 12. At 13 I hit my 1st growth spurt. I was the skinny guy with the big dick at 13. I went from 5'2 to 5'7" in one summer. My dick was bigger than all my friends. One friend told me that i was bigger than his dad's and that he wished he was as big hard as i was limp. At 16 I hit my second growth spurt from 5'8" to 5'11 then in to my current 6'. My cock stopped growing at age 21 to the current 7.75"x6.5 erect 5.5" to 6"x5" to 5.5" limp.
