First here’s the measures:\nErect Length\nMODEST 14 cm. (5.5")\nAVERAGE 16 cm. (6.3")\n\nErect Circumference\nMODEST 11 cm. (4.3")\nAVERAGE 12,5 cm. (4,9 ")\nAbout teens there’s no a precise statistic because the sexual development doesn’t start at the same time for anybody as like as haven’t a prefixed stop. Besides it useless to verify the possible average length during the development, since it’s only a provisional value. It’s better to wait the apex of development (around 15-16 y/o) when the penis development is completed.  \nThen remember that good and satisfactory sex isn't measured by penis lenght only!

Statistically speaking, the average male has an erect penis that measures just under 6 inches in length. The asian average is a mere one-tenth of an inch less than white men and black men are one-tenth of an inch longer the white guys. Now, if you are designing an airplane maybe a tenth of an inch is significant, but when it comes to sex, length really doesn't matter and a tenth of an inch certainly won't.\n\nPenis length has no relationship to shoe or hand or nose or any other body part size. I've observed guys with size 2 feet who have 6 inches and guys with size 7 feet who measure 7 inches or more. And some of the biggest noses I've seen are accompanied by average penises at best. And even though there may be a case for genetics, some men have sons with way bigger penises and vice versa so who knows on that one either though maybe further research will prove it is inherited from your mother's father or something.  \nIn any event, just write off your size to a decision made by mother nature and learn to use your penis really well so you and your partner enjoy every minute you spend with it.

The penis size cannot be increased although many will purport to be able to do so. There is a surgical technique that can release the muscle at the top of the penal shaft but often the penis when erect will droop even when fully erect. The average adult male penis size is 4.5 - 6.2 inches.

5 and a half to 6 and a half inches. So now if you fit that category, the next time your girl talks about your penis size she will say, oh, he's average. lol

of course this varies from person to person, but here's the statistics on erect penis lengths for white college men, in quarter-inch lengths measured by The Alfred C. Kinsey Institute for Sex Research (from the point where the penis meets the body along the top to its tip):\n\nhttp://www.edu.uni-klu.ac.at/~amiklaut/dr_nick/answer19.htm\n\nbasically anywhere between 3.75 and 6.5 in

In response to Dramaguy's answer telling you to take these questions elsewhere, I will say there is nothing wrong with your question. This is the Men's health section and you have a valid question about male anatomy. If Dramaguy is ashamed that he has a penis he should probably seek counseling. The average size of the male penis is 5 1/2 to 6 inches.

The average size for us guys is around 5 inches or so. Be careful of exaggerations that simply cannot be true. The size of a private part is the same as the distance between your thumb and index finger, by the way. Our bodies are proportioned.\n\nOnly if you are especially tall might you have 7 inches.  Not likely.  Perhaps your way of measuring is distorted.

When erect 5 1/2 to 6 inches.\n\nNeat additional foctoid....there is a difference between races and penis size.  Asians are the smallest and American indians are the largest.  Now how much of a difference between the averages...from the smallest to the largest race the grand total of difference is less then half an inch.\n\nHite report on Male sexuality

Statistically the average is about 6 inches when erect. Naturally since this is an average, that means that HALF of men are smaller than that!\n\nThere are many women who prefer larger penises, but there are also many who prefer a smaller penis.\n\nIn a survey on SwinglesOnline.com the question was asked of sexually active women.\n\n22% said that size did not matter to them at all\n7.5% said THEY PREFER smaller than average\n25% said they preferred slightly larger than average\n18% said that too large causes pain\nonly 14% said they prefer a large penis\n\nThe remainder indicated they were lesbians and had no opinion.

The ordinary size for us guys is around 5 inches.  It is not all right for you to exaggerate or make such outrageous claims.  If you stretch your index finger out, the length from your index finger to your thumb is the length of your private part.  Every portion of your body is proprotionate to the rest.  So it is not possible that you could ever have such a ridiculous claim.  It is better for you to be truthful and honest with yourself, and then of course with others.\n\nMost 16 year old guys have enough self esteem to be proud of who they are and what they have.

Okay, getting past the more flippant comments, no, 13 centimeters is not small for a human male's penis.  Depending on which study you check, average is between 5 and 6 inches, or between 5 1/2 and 6 1/2 inches (when they're erect, contrary to popular opinion), with well over ninety percent of all males having a penis that size.  Thirteen centimeters falls right within that range, being a bit over five inches long, so you're a healthy, average male when it comes to the size of your penis, and shouldn't be worried about the matter (since there's really nothing you can do about it anyway).  I actually answered this question in much greater detail on Amorous Propensities, so you might check there.  \n\nAlso, you should beware of techniques and supplements that prey on your insecurities and promise to increase the size of your penis.  There is no known way (except for surgery) to do it... and the FDA and AMA have checked every single last one of the "miracle cures" out there.  None of them did what they promised to do, and quite a few of them (such as vacuum pump, stretching the penis with weights, etc) are very harmful to your penis and may damage it enough to prevent you from being able to get and keep an erection.\n\nBelieve it or not, your ability to satisfy a sexual partner will be more dependent on your technique than how big your penis is, so now that you know you're up to snuff anatomically, you can concentrate on more important ways to please that special someone.  If you have further questions, please feel free to ask me if you want to.

You can't length your penis baby!  Pulling on it won't help, pumps won't help and pills won't help!  Sorry, nothing works!  Just be happy with what you got!  The average size of a man's penis is 5 1/2 in. erect.  Real women don't care about the size of anyway!  We just want you guys to make us feel good!

the average penis size in the U.S. is 5 and 3/4 inches. average time to ejaculation depends on mood, length of time between sexual encounters, penis sensitivity, stamina, the fact of whether or not he is sober or inebriated, and probably 100's of other factors.

If it is under the average of the normal size of a man's penis,then I would say that is small.\n\nBTW 5"-6" is the average size for a man.
