The (statistical) Truth About Cock Size

I must be in the company of giants. So all the big dicks are at Thunders then?

You are not lying lol. I feel that if you are above average on Thunders, then you will be more then above average in the your community.

Men of the world, rejoice! The average length of an erect penis is shorter than you probably think.

A study by Lifestyles Condom Co. shows that the average length of a male sex organ is 5.877 inches — which might comfort men who previously thought they were less than average.

"The Kinsey Sex Report and other penis size surveys have indicated that the length of the penis is 6.2 to 6.4 inches," says Simon Joseph, a spokesman for Lifestyles. "Our results show that about three-quarters of men fall under the average quoted by Kinsey."

"A half-inch or less might not have anything to do with how you perform sexually, but it might make a difference in how you feel about yourself."

According to the survey, about two-thirds of the 300 college-aged men ranged from between 5.1 and 6.2 inches.

For those of you who don’t like to deal in raw numbers, at 5.877 inches, the average penis is about the size of a Nestle Butterfinger candy bar (unwrapped) or a grande (medium) cup of coffee at Starbucks (with the sip lid). Most men vary in size between a Twix bar and a Peter Paul Mounds (with the wrapper extended).

When Alfred Kinsey did his groundbreaking research in the mid-1940s, researchers simply gave men stamped postcards. Each one simply held a postcard against his erect penis, marked how long it was, and slipped the results in the mail.

"They never had to hold a ruler against themselves," says Kinsey spokesman Jennifer Bass.

Measuring an erect penis is no easy matter. Kinsey, Masters and Johnson, and various urology groups have been satisfied with either letting the men do it themselves or with surveys of a few dozen volunteers.

But condom companies need more accurate measurements for the best-fitting products — even if sex experts assure us that size doesn’t matter. Lifestyles says it did the largest and most accurate measure of penis size ever just three weeks ago. Company representatives went to Cancun, Mexico, at the heart of spring break, hoping to get 1,000 guys to drop their trousers, get aroused, and let a team of nurses measure them individually.

The guys got to go into a private tent outside Daddy Rock nightclub, where they found girlie magazines and other items to put them in the mood. Then came the doctor and two nurses. Each penis was measured by two of the four nurses.

"It was a highly professional operation," said Dr. Francisco Ordonez, who supervised the research. "The nurses wore disposable latex gloves and the men were all good-humored and well-behaved."

It’s amazing what some college guys on spring break will do for some free T-shirts, condoms and other prizes. The researchers thought holding the testing in such an environment, where guys tended to cluster in bunches, would help get true variety.

"In other tests, guys responded individually, and perhaps only guys who were proud of their penis size would respond," says Joseph. "In this test, we thought peer pressure would help coax guys who wouldn’t ordinarily do such a thing into doing it."

Still, when it came time for measuring, about 25 percent of the guys weren’t up to the job and had to face a little humiliation in the name of science.

Ordonez and his team had to be satisfied with 300 respondents. That’s far fewer than they hoped for. But it’s nearly twice as many as a similar study in Brazil last year, which had similar results.

The Importance of Girth

"It’s absolutely important that we have the best information to make the best-fitting condom," said Carol Carrozza, Lifestyle’s vice president of marketing. "If a condom is too tight, it constricts circulation. It’s uncomfortable, and it reduces sensitivity. If it’s too loose, that’s dangerous."

Carrozza says the circumference of the penis — otherwise referred to as girth — is often more important than length when new condom sizes are considered. "Because of the way condoms unroll, it’s really not the case that they are not long enough."

According to the study, the average erect penis had a girth of 4.972 inches. About 75 percent of men were between 4.5 and 5.5 inches.

"We already have a larger condom," says Carrozza. "What our research shows is that 17 percent of erections measured under 4.5 inches, and there might be a market for that."

Of course, once again, the frail male ego comes into play, and while condoms come in large, studded, ribbed and flavored varieties, you don’t see small or petite or narrow models. We’ll just have to see what kind of circumlocution the marketing folks come up with.

The following article has some bearing on the legitimacy of the results from the oft-quoted Mr. Average site (http://www.mrav … com/results.htm ). Thanks to Lampwick for finding it.

Let’s assume that the figures in bold are accurate. This is a reasonable assumption if we think that the author of the article is interviewing someone who had direct access to the raw data. Now, if we go to the Mr. Average site and tally up the percentage of girths under 4.5", we get 33.8%. If we do the same for the percentage of men between 4.5"-5.5" girth, we get 57.2%. In both cases, these figures are off significantly from the numbers in the article. A similar argument can be made regarding the length data (with respect to the 5.1"-6.2" interval). This suggests that the Mr. Average graphs are suspect, adding more evidence to points previously advanced by Priapologist and Para-Goomba.

But that’s not all; we can extract some more interesting information from these figures.

If we assume a normal distribution for the length data, then the percentage of men between 5.1" and 6.2" is about 48% if we use the mean and standard deviation from the study. This does not coincide with the 2/3 figure given in the article. This suggests that the length data is not exactly normally distributed. In particular, there are less big and small penises than might be expected from a normality assumption.

Moreover, assuming a normal distribution again for the girth data, the percentage of men under 4.5" is about 17%, agreeing with the quote from the article. However, under the same assumptions, the percentage of men that should lie between 4.5"-5.5" is about 67.4%, which is under the 75% figure given. This suggests that girth is also not exactly normally distributed. In particular, the distribution seems to display a negative skew and positive kurtosis. This means that more girths are concentrated on the lower end of the distribution than the upper end. It also means that more girths are clustered near the mean than might be expected from a normal distribution. To put it simply, most penises don’t differ that much from each other in girth and thin ones are more common than fat ones.

just a thought guys….

The LifeStyles Condoms research was conducted in Cancun , Mexico .

If you research the Ethnography of Mexico and specially in the Cancun area (Quintana Roo State) , you will realize that there is a large population (40%+) of pure Amerindians(indigenous peoples of Asian origin) with a lot of Mestizos ~50% (those of mixed European and Amerindian ancestry) and with a >8% of pure European origin and >2% African origin in the region … (but then again since it was performed in a university the % of Caucasians might be much much higher…)

Comming from a country that consists of 99.5% Caucausian ( I’m half GreeK half French ),IMHO I hardly can think how the Lifestyles results can relate with me :P ………just a thought

This study sample was 300 American spring breakers…college kids who probably were overwhelmingly white. So yes, its a racially fairly narrow study but should be pretty relevant to you personally.

Woohoo! this makes me feel better about myself!
