The above answer is correct, on average. \n\nAn OLD rule of thumb (penis?) was to assume 1" of length for every foot of a man's height.

All 15 year old boys act weired and even when they grow up men tend to get weired when they are with a group of guys.  What you are experiencing is perfectly normal.  You have nothing to worry about.

Most of the answers here are ridiculous.  The truth is that the average penis is only about 5 - 6 inches fully erect.  It's also true that penis size is irrelevant to pleasing a woman -- it's not how much you've got, but how you use it.

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!

Like you're going to get the truth. If you don't make the measurements yourself all you're going to get is 8,9 and 10" guys all of whom will be lying through their teeth.\n\nGo with the University of California study. 5.1-6" long erect and 4.2-5.5 in circumference on average.

This is one of the most commonly asked question on yahoo answers, Please read this, at the bottom it has info on penis enlargement…\n \nJust about every guy wonders how he measures up in the “down-there” department at one time or another. Here’s the lowdown for any guy who’s ever worried about whether his penis is a normal size. \nThere’s a fairly wide range of normal penis sizes - just as there is for every other body part. And just like other parts of the body, how a penis appears at different stages of a guy’s life varies quite a bit. You wouldn’t expect someone who is 11 years old to look the same as someone who’s 19.\nGuys normally develop at different times. Some may start developing as early as 9. Others may not start developing until 15 or even later. The age at which a guy starts to grow varies from person to person. It all depends on when he enters puberty and his hormones start doing their thing. \nGrowth in penis size is just one part of puberty, which also includes such changes as pubic hair development, testicular growth, muscle development, and a growth spurt. Late starters almost always catch up fine - they just reach full maturity a little later. \nPenises come in different sizes, shapes, and colors. These traits are hereditary, like eye color or foot size, and there’s nothing you can do to change them. Despite what you may hear or read, no special exercises, supplements, or diets will speed up the development process or change a guy’s size. Also, like his feet, a guy’s penis may appear smaller to him just because the perspective is different when he’s looking down. And there’s a lot less difference in penis size between guys when they get an erection (a “boner” or “hard on”) than when their penises are relaxed.\nIn addition to size, guys also wonder about other aspects of how their penises look, such as whether the skin covering the penis is normal or if it’s OK for a guy’s penis to hang to the left or right (it is!). If you’re concerned about how your penis looks, ask your doctor. Guys who are reaching puberty should have regular testicular exams, so that’s a good time to ask your doctor any questions. \nTaking a ride on the hormonal roller-coaster means lots of changes - and a lot of common worries - for both guys and girls. Just as guys may wonder about how their penises develop, lots of girls ask the same thing about their breasts. \nIf you’re wondering about your development, don’t try to compare yourself to your older brother or your best friend - they’re probably at a different stage of development than you are anyway. The important thing to remember is that it’s OK to not be a mirror image of the guy at the next urinal. \nGet out the tweezers and the microscope :)\n\nYou probably have a good sense of where you fit in the distribution of size for\nmore commonly visible measurements of body size: height, size of hands, feet,\nweight and so on. However, unless you spend a lot of time in a nudist\nenvironment, there are, understandably other measurements for which you don’t\nhave a good sense of where you fit. Penis size is an obvious example. It’s also\none that can make a lot of people uncomfortable. They worry about whether they\nare abnormal, “too small,” “too large,” and so on. As with most characteristics\nof human anatomy, there is a lot of individual variation. You can differ\nsubstantially from average without being unusual or freakish and without any\nneed for concern or medical intervention. If you have concerns, by all means\nconsult a doctor, but chances are good that you have nothing to worry about.\n\nOn the other hand, there is always a fascination with people who are\nsignificantly different for the normal range. This applies to height and\nweight, size of hands and feet, and, yes, also to penis size. So what\nis “normal”? Surprisingly, perhaps, given how common concerns about penis size\nseem to be, there are very little

in between 5 and 6 inches when erect.  That's the average for all men because by 21 you've reached sexual maturity.

I took these measurements from a medical book so trust them\nmean length of penis size of a guy 18 years old if he is\nCaucasian : 6.5"\nBlack : 6.1"\nHispanic :5.9"\nAsian : 5.5"

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.

13.5 " (ouch)\n\nNEW and IMPROVED Penis Length info:\nAverage white tool: 6.2 inches long and 3.7 inches around. The average black schlong: 6.3 inches X 3.8 inches. Let's see, that's a 0.1 inch difference. So who's been hyping this one?? Another bit of bullshit exposed by the scientists at The Blur of Insanity!\n\nLargest Penis Recorded!\n(yes, on a human, not a horse):\n13.5 inches long and 6.25 inches around (documented in the early 1900's by Dr. Robert L. Dickinson). That's some serious meat. In case that makes you feel inadequate, there have been cases reported of Micropenises (less than 1 cm in length). \n\nThe average asian penis is 5.5 inches in length.\nAlthough the average asian penis is a little short, there are other things to consider. The taoist art of Chi Kung involves lifting weights with your penis. The record for this was set in 1995 by a Hong Kong master named Mo Ka Wang, who lifted over 250 lbs. two feet off the floor WITH HIS WILLY. We're not sure exactly how this was accomplished, but we're pretty sure that Miss Blur of Insanity was NOT involved.\n\nDr. JÀrn Ege Siana, a Danish plastic surgeon holds the record for greatest penis extension. He took a 48 year old's 1.8 inch wang and added 5.7 inches. Of course, it was probably the width of a #2 pencil when he was done, but what can you do?

4.5-5 inches is a little under average, but not horribly small.  One thing you can do is NOT pay attention to all the hype about penis enlargement, none of them work!

75% of men have a penis 6" or smaller, with 6" being average. The remaining 25% of men are considered large. As the penis size increases beyond 6", the percentage of men decreases sharply e.g 9.5% have 7", 1% have 8", and 0.1% have 9".
