For me it was the opposite: I was very hung as a little boy, but now as an adult I am fairly average, or a little above average.

I was an early bloomer and hit my puberty at 10 years of age, when I got my first hair on my dick. I remember the other boys teasing me a little, but nothing that really disturbed me. I do not remember measuring my dick at that age, but I know for sure that when I was 13 yo I measured it and it was 17 cm., and it stopped growing already at 14 at 18.18,5 cm. (about 7 inches or 7 1/4 inches...I am not good at american numbers hi hi).

But I know it was fairly big for my age already at 10 or 11. Because I remember having a big erection during a swim-leason when I was 11 and I remembering being a litttle shy about it, trying to hide it. Probably when I was 11 it was about 13-14 cm ( 5 ½ inches, I think).

But I remember some of the other boys having very small penises at 11 or 12 but some of them catched up, and one boy named Kim ended op having more or less the same size as me (I just happened to see him with an erection when he was 18 yo), even that when he was 14 he almost did not have any dick at all!
