so, im 16 years old, i hit puberty at about 13, i have armpit hair, facial hair, deep voice and all that, but my penis is really small. i do not measure it or anything, but it is REALLY small. could this be because i am a pretty large boy? i weigh about 140 kg
Hi Anon,
Average for an adult is 5 - 5 1/2" if that helps.
Body fat can make your penis smaller, if you have any fat at the base of the penis. It can easily make it an inch or so shorter so work on the weight.
Your penis can grow into your early 20's. Some guys just get bigger later. Hang in there.
