You don’t have to have been a member of LPSG very long to have seen a lot of “What is Large?” questions and variations. These are legitimate concerns, especially around here, and apparently a lot of people really don’t know but these questions get asked with such frequency, especially by newbies, that I have embarked on creating a completely unofficial and unauthorized FAQ on the subject of penis size. This way there will be a place to refer new posters when they again ask, “Am I big?” or seek to start another round of guessing their dimensions. This is a very short, down-and-dirty version. This is just the stuff you need to know: Length: The average size of the erect human penis is 5.3 inches. (13.5 centimeters). Roughly 75% of men are within 2 centimeters (a bit less than an inch) more or less of that measurement. So, if you are between 4.5 inches and six inches in length, (11 to 15 centimeters) you are pretty much average. Above or below average is anything that lies outside those parameters. Girth: The circumference of the average erect penis is less well documented than length. Best estimates put the average at about 5 inches (12.6 centimeters) in circumference, but the studies are fewer and less reliable. 4.75 inches to 5.25 inches (11 to 13.5 centimeters) seems to be the “average” range. Volume: Total penis size is a combination of both length and girth. This is often called “penis volume.” (To help visualize this point: A roll of Mentos and an average soft drink can are both 5.5 inches in length, but they are of really different sizes, because their circumference is so different. Even if the Mentos roll was twice as long, it would still be smaller than the soda can in total volume.) Monica Lewinski’s notorious description of Bill Clinton’s erection as being about the size of a roll of U.S. quarters turns out to be a pretty decent visualization of the average human penis. (Sorry that I don’t have a ready comparison for world readers, but perhaps some of you can help supply appropriate equivalents of everyday objects that are not so Americentric.) The typical joke comparisons to bananas are, well, extremely optimistic. Flaccid: There is not only no steady relationship between the size of men’s flaccid penises and their erections, but there is no reliable average “flaccid” size for most men. We all tend to experience a great deal of variation from hour to hour, ranging from “frozen shrinkage” to “sporting a semi.” Some men (often called growers) can experience huge variation with their penises tripling or even quadrupling in length from the smallest flaccid state to full erection. Others (labeled “show-ers”) experience little change. It just stands up. Unfortunately, then, almost all talk about flaccid size is basically unhelpful. No real conclusions can be drawn except that if you see someone who is larger flaccid than you are hard, then he has a bigger dick. Size ranges: Rounding off slightly for convenience, one inch (2.5 centimeter) increments seem to correspond with standard deviations from average. The vast majority of men, as noted above have penises plus-or-minus one inch of 5.3 inches. Only one in 10 will exceed 6.5 inches (or for that matter, be smaller than 4.3 inches.) Only one in 100 will exceed 7.5 inches (or be smaller than 3.3 inches). Only one in 1000 exceeds 8.5 inches. Only one in 10,000 exceeds 9.5 inches. Only one in 100,000 exceeds 10.5 inches. Only one in 1,000,000 exceeds 11.5 inches A penis that exceeds twelve and half inches is a one in 10,000,000 rarity. I may add more here from time to time, as I am sure will others, but with just this much information in hand you can quickly figure out for yourself where you stand. More detail can be found on Wikipedia under “Human Penis Size.” I heard that average was bigger: The famous Kinsey study released in 1948 placed the average length of an erection at 6.2 inches (16 centimeters), and because this was the first important study this information has long been cited as definitive. Over time and with more studies, however, even the Kinsey institute has averaged downward to the current best estimate of 5.3 inches. There are many studies out there with conflicting results, but it can be clearly seen that studies in which participants measured themselves and reported their results always average longer than those in which staff members take the measurements. Studies which have all volunteer pools also invariably average longer than ones in which there is random selection process or, in the case of several military studies, where the participation was compelled. (Not surprisingly, guys with bigger dicks are more likely to volunteer for size studies than men with small ones.) Estimates of average lengths exceeding 6 inches can pretty clearly be shown to be the result of unrepresentative pools, or unreliable self-measurements by participants. What about racial differences?: When penis size studies first began being issued immediately after WWII statistically significant but small, i.e. half-inch, differences were found between the average erect sizes of men of different races. However, overall body size studies at the same time also showed distinct differences between races that have tended to disappear over time as nutrition around the world has evened out and improved. Some sixty years on, the overall physical averages between races have greatly reduced in variation. (Better nutrition is generally held to be the reason, but better – that is, less racially biased – experimental methodology may also account for this difference.) Newer studies suggest that if there ever was a real difference, penis size has now also evened out. Studies are conflicting in this regard, but the older the study the more likely it is to find significant racial differences. Despite the persistence of the rumors, and they pop up here at LPSG repeatedly, there is no evidence that size difference is racial rather than individual. (A word of advice to newbies: Posting your anecdotal experience about racial differences is rarely well received.) Does Size Matter?: As one of our members says in his signature line, “Size does matter, but not in the way you think.” We tend to strongly associate penis size with masculinity, virility, power, and sexual expertise, especially in photographs. None of those are necessarily true. Think of the analogy to height and its association with basketball. Being tall does not, alone, make you a basketball player, does not alone make you athletically talented, does not alone make you even interested in the game. There is a loose connection, but being a tall man myself, I know I get a lot of unearned credit for my ball playing skills (or those imagined about my past) that just has no factual basis. Likewise, at LPSG you will find men with all penis shapes and sizes. It won’t take you long to discover that some of the big-dicked men here are hyper-masculine and oversexed, but so are some small ones. (And some big members are not so masculine and undersexed.) Some of our giants find they are powerfully attractive to sexual partners without doing much to further that cause, but so are some of the average and small-endowed ones. (Some big guys are virgins or at least have trouble finding a date.) There are men here who are statistically way off the charts who love their endowments, but there are also men here (and you may find this hard to believe) who wish their penises were smaller. By and large, your dick is what it is. Look around and you will easily find information about making the most of what you have, and dealing with the reality of it whether it be abnormally outsized or perfectly average. Just some final, simple advice: Don’t lie about your size. Don’t bother to brag about your size if you don’t post a gallery, even if its true, ‘cause no one will pay any attention. Don’t post a photoshopped picture, and don’t post a picture of someone else’s penis. We’ve seen it all. You get caught every time, and it serves no purpose. The members are perfectly respectful here of real penises of all shapes and sizes. And they are ruthlessly cruel to the liars and fakes.
