in my early puberty, I slowly got hairer. penis grew longer but remained very thin, then right after turning 15 in the time frame of about 2 months my balls got huge, and my penis must have tripled in girth. I remember my pants getting tight, and my genitals were actually in the way when I walked or ran. my older brother was home for the summer and saw me getting dressed, and commented that I got the "old man's dick." my mother wanted me to wear very loose pants, no Levi's. and that fall I went in for a sports physical with the same doc I had for yrs. we got to the hernia test, and the doc looked an my dad, and said something like, "you son has gone thru puberty very well."
