I could be wrong but i think between 13 to 24 and once you hot 24 that it will be the biggest it is going to get but cant say that is 100 percent acurate info

I stopped about 15/16.

I think my cock was full size by about 13 years old

21/25

But it's science's view. Mine stopped at the middle school.

Not sure but mine stopped around 16. I wished it would continue to grow.

.

I honestly don't remember,but considering i get my shoes wet if i try to pee sometimes,it quit growing to soon

mine stopped around the age of 5 or 6

I developed late so I think I was 20 when I got fully grown.

I was 13 years old and measured 7 1/4 inches long when I was hard and 5 3/4 inches in circumference. It never grew any bigger from that time on. I’m still the same size today just a little bit thicker

they dont grow. the penis is an organ its size is relative to curculation. you want size you need to treat yourself.

My dick has been the same size since about age 15.

Never. Schape changes over the years a bit. I am in my 50ies now, LOL

every time i see hotness...it keeps growing.

Mine grew till age 21.

My cock maxed out at 6.5"erect and has stayed the same most of my life!

Quite variable. It usually has achieved its longest and thickest by 19.

Mine maxed out about age 20-21, at about 7.5". At age 50 it began to slowly lose length, though it is still as thick. I'm in my mid 60s now and it's 7", so still long.

I'm in my 40s and my dick is as big and thick as it was at 20. So it depends on body shape too. If overweight then the body draws it upwards and it can be smaller. Also there is some evidence that higher testosterone can make it smaller when developing. Often but not always, a hairy bald male has a shorter penis. But not in everyone just higher %. This is from an endocrinologist study.

I don't think the cock keeps growing forever. Mine has not. Good thing too or else it would look like an elephant trunk.

I don't know when it stopped getting bigger. It has always been pretty big, bigger at least than my age group in school PE or sports. I was mostly small through school, with a huge cock. About 16 years old I put on a growth spurt and by 17 was about my adult size, my cock followed suit. As I grew, it grew. So by, 18 I was filled out and so was my cock.

As it started to get some serious use fucking, it might have increased in volume a bit. Not longer, but thicker. Probably by 20, it was as big as it was ever going to get. Good thing too, by then it was scaring off most women who just didn't want it inside of them.

I think its really rude to disparage someone's dick. After all what exactly did you do to get a larger cock? Ill tell you absolutely nothing!!! You are simply a result of your genes. That doesn't make you special. Well, I guess some think it does!!

I was full grown by 13 or 14. Alot sooner than most my friends. But they seemed to catch up over the next few years

I think mine quit growing about 14 or so.

As I was 16 my dick stop to grow.

My cock did not shrink with age. It changed its shape with years from young to more "adult", I think.

Don’t kno wen they stop growing but wen u get older they start shrinking

full grown age13

For some guys on here, looks like there dick stopped growing b4 birth

with most guys in puberty it starts to show real growth length and thickness around age 12 /13 and continues to grow up to age 18/19 .

My guess is just after puberty

My dick more than doubled in size from 4th to 6th grade. I was bigger than the boys my age and many guy a lot older too. But by high school most of them caught up

Mine reached its full length when I was 13. It got thicker, however.

Mine stopped growing at age 10 about.

my dick has been this size since 6th grade. Got size very early

The typical age when a guy's cock reaches its final adult size is ~18 - give or take a year. Of course, there are exceptions - but that is the norm.

My erect size when I was around 22 years old and the softie some years later.

Mine stopped growing at age 16 or so.
