at the age of 15 how many inches should it be??
Answers:    At least 6 inches long.
i'm 17 and mines around seven and a half inches and thick, but it has grown a lot in between the age of fifteen and now so try not to be to concerned about it. i think mine was a little above 5 inches when i was fifteen. every dude is different cuz we all have different genes so u never no when ur gonna start growin. i started arond 13 and i grew about a foot and a half in between then, and now and some of my friends started to grow when they were 11. its true that ur * grows with ur body trust me. so look at everyone around u in school and figure out if ur a little bit slow in growin.
Well I'm 14 and mines is about 6.5" if that helps you any :)
Spike, Mikey and James above are confident boys and apparently are well endowered as expressed by their desire to share such intimate information with the world. They are no doubt, studs.

But at 15 there will be a wide range of variation between males of the same age. That is how it should be, because, as spike suggests, some boys mature earlier than others.

If you are seriously concerned, see your doctor, otherwise ask your friends and as a general rule, deduct around 4 inches from their position statement.
4-6 inches is average for 15. But of course some could be lower or higher but its rarer. I'm 15, and its 5 inches. You'll grow more though, until your 21.
I will tell you right now that most people will lie and exaggerate their answer when you ask them. Their have even been studies done that prove this...so you could never know.

Also, Spikes above said, "its true that ur * grows with ur body trust me."
That is a very ignorant and stupid answer. That may happen for some people, but by all means not everyone. Different growth hormones which are responsible for growth in different parts of the body are released at very different times. So while someone may be very tall, their penis may have not started growing.

At 15 you don't need to be worried, I had a friend that at 14, his penis looked like it had not grown at all...literally, it was like 2 inches when erect.

I'm 18 and mine is about 5.5 inches. Even at my age it is possible for more growth to occur, but I'm not counting on it. As you get a little older you'll realize that it doesn't matter as much.

When I was 15 mine was about 4 or 4.5.
12 inches
whatever you have now
Around 6 inches is average for an adult, and by then, your penis is probably done growing.
mine is 8 inches, oh wait i'm a girl i dont have one, sorry!! :-(
It's going to be as big as your genetics allow. You might as well stop worrying now. You do not need 7 or 8 inches to be a stud. You will, with time, learn to use what you have. No matter what the size, it's yours and it's going to be with you for a lifetime. We have to deal with what we have been given.

Austin R is right on the money, most men wont tell you the truth, first because the dont measure correctly, and since you wont ever see how big they are, they’ll just say "im 6.5 or 7 or 8", but then go on to claim that the average is 5 or 6 inches, the rule usually is take 1 to 2 inches off what a guy tells you if it sounds unreal. But to tell you im 18 as will and im done claming that im 6 or more, im just a little over 5.5 inches, and thats ok, and average, as a general rule most men will end up around 5 to 6 inches, but the average range is 4 t o7, at 15 i guess i was probably just under 5 or just over 5 inches, but you still have a lot of time to grow, i thought i was done at 17 with about 5.25 inches, but it grow a little more, i didnt even realize it, so just let it grow. The average girth is 4.75 inches, but ranges from 4.5 to 5.25.
Here we go again with another "penis length/size" question. There is not much of a relationship between belly size and penis size. Your penis size will be the size you are given! There are no pills or creams, no toys or tools that will make a penis longer or larger. Any product claiming to do that should be regarded as being suspect. Likely it is a scam and the only thing that will get bigger is the wallet or bank account of the person/company offering the product. Look closely at the promotions and you will see that the product is not tested, inspected, approved or endorsed by any reputable organization. If it works why has it not been submitted to the U.S. Federal Food and Drug Administration for FDA Approval. If you are concerned that your penis is not large enough then consider that the average length is 5.5 inches and frankly that is plenty large enough. Read some of the posts from females who are afraid of the "huge" penises out there. Sure the "American thing" is "bigger is better" but that is not always the case. If you are concerned about the ladies pleasure - and that should be your main concern, you should develop a technique or style that makes the most out of what you were given.
It is important to remember that sexual intercourse is not simply a piston going back and forth at a high speed. Actually a lot of the "jocks" haven't figured that out yet. If you work at developing a style you will score more and it will be more fun for both of you.
And it will be fun learning the technique.
And if you are still wanting to do something to make your penis bigger, each night before you climb into bed, get down on your knees, bow your head, and pray for a larger penis. Trust me, you stand a better chance this way than with any tools or toys.
somewhere over 2 inches depending on your genetics, how far through or into puberty you are, whether you are outdoors naked in winter or inside by a nice warm fire and lots of other factors.
