LOL...this brings back a lot of memories...
My problem was that I went through puberty way before everyone else so that in middle school when we first had to use the big communal showers, I was already hairy---and my cock had already started to fill out to a more adult size. Then, to top it all off, I was also the smallest guy in class. So, between the hairy jokes and the short jokes, it was also the "gee, for a little guy you sure have a big dick" comments that just wouldn't end.
Now, my dick is "normal"---although maybe still a little large for my height. And, of course, now I wish someone would still be able to say the same thing about it. But, back then, anything that made you stand out from the crowd was a real ball-buster.
