I was about 12 or so, I started getting pubic hair. and that's when I got curious. it was back in the 60's, no porn back then compared to today. at that age & time, you looked around very little, mainly just to see if anyone else had hair down there. we all knew what was going on due to sex education, but we didn't talk about it a lot. in the next yr or so as more guys puberty set in, locker room chatter increased. also, during the year, my penis grew longer, but thin. my body and some facial hair was growing. I was also growing quite tall. about the time I turned 15, my ball size and cock thickness grew very fast, large/thick in just 2 months. our sophomore year, the lockerroom conversation would go to cock size, some, like myself, were 98% full grown. some of the 98% guys were quite proud of themselves. I tried to play it cool cause everybody was in various stages in puberty. heck, at 15 some of us were done growing, swinging some cock, and some guys didn't have a pubic hair yet. the teachers were well aware of this and tried to downplay the sex aspect. we were taught to wrap a towel around ourselves when going thru the locker room. but it wasn't a set rule and some guys were more exhibitionist than others.
I started walking thru w/out a towel after I overheard some gals talking about a few guys cock size. I knew all of them. I figure somebody was spying or talking. either way, I couldn't lose, and I might get a reputation, so I showed my new 'self' also.
and you know, a year later, no one really gave a shit. so many guys had matured, there were lots of big cocks, no big deal. plus, we all knew each other for the most part. we went thru puberty together, woo hoo! and not a one of us had any control over what we wound up with. I wound up hung like my dad, my bro did not. I considered myself lucky, or blessed or both. I thought I was going to have a long skinny cock to match my tall slender stature, and wound up with long & thick, big balls. I never heard too many comments. my black friend said, I didn't get cheated. I heard a few comments the first couple weeks of my sophomore year, cuz I had grown over the summer. showering after PE class or basketball, I heard, "look at XXX, he's big now." in a whisper. but hey, they look, move on.
