Dick Data Part 1: A Deep Dive Declassifying The Diminutive Differences In Dudes' Dick Lengths

There seems to be a fair amount of discussion here about penis lengths and sizes. Some guys wonder if they're "average" or not. Some guys wonder what women think of various penis sizes and what they find more or less attractive. Some guys wonder if the size of their penis is affecting the the quality of their sex life or relationship status. Pretty much all girls wonder why so many men are wondering about the size of their junk, but that's beside the point.

Well, do I have a treat for you today... The definitive guide on "Dick Data", as I'm now calling it, for GaG users of all genders and persuasions. From now on, if you see someone on here asking a question about penis-related measurements and statistics, you can just drop a link to this MyTake on them and walk away knowing they're in good hands.

So, let's dive right in, shall we?

First off, why am I qualified to compile, analyze, and present to you this data? Great question. I have a doctorate degree in the medical field (which I won't specify the nature of due to anonymity concerns), but it required me to become rather skilled at interpreting and presenting very difficult to understand raw clinical research papers. For those of you who are wondering what's so difficult about that, well, there's a big difference between a random website discussing "a new study" and the actual study itself. Sites written by journalists and editors intending to entertain often only present data from studies that is "interesting" or alarming, but very few editors and journalists have spent 6+ years in a graduate program in the medical field specifically analyzing raw clinical research study data. Ever wonder what the news outlets mean when they say "a new study"? Where is that study published? Where can you go read it?

Fear not, my friends, because I've utilized my half-decade of experience in clinical data analysis to do the hard work on your behalf. I've scoured clinical journals from all across the internet to finally get to the bottom of the age-old question: Is my dick normal?

First of all, I'll just present you with the raw data since that's likely what you've been waiting for this whole time, anyway, and then I'll do more of an analysis afterwards explaining what I did to compile and interpret this data and what it actually means so you'll know that I'm not just full of B.S. and making up random numbers. I will also leave links to the sources of the data so you can verify for yourself if you are so interested in doing so. Here it is:

Data Points Analyzed

1) Average flaccid penis length, globally, pendulous (just standing there, basically): 3.61 inches

2) Average flaccid penis length, globally, stretched (flaccid penis stretched to full length, but not erect): 5.21 inches

3) Average flaccid penis circumference ("girth", or distance around widest area of penis shaft), globally: 3.67 inches

4) Average erect penis length, globally: 5.17 inches

5) Average erect penis circumference, globally: 4.59 inches

6) Average erect penis length, U.S. males, pendulous: 5.57 inches

7) Female penis length preference: Undetermined/variable, but generally within the range of length considered average.

8) Female penis circumference preference: Undetermined/variable, but generally within the range of circumference considered average.

9) Do women find larger penises more attractive? - No, with exceptions and clarifications.

10) What penis length is considered small on a clinical/medical/statistical basis? - 1.54 inches flaccid or 2.95 inches erect.

11) Are most men happy/satisfied with their penis? - For the most part, yes.

12) Are most women happy/satisfied with their partner's penis length/size? - Yes, almost overwhelmingly so.

13) Does penis LENGTH affect condom breakage/slippage? – Undetermined, but most likely not.

14) Does penis CIRCUMFERENCE affect condom breakage/slippage? - Yes.

15) Do men exaggerate or over-estimate their penis length/girth? – Yes, most likely, though not actually validated very concretely as far as I could tell.

16) Do men tend to think they are bigger or smaller than average? - Neither, but more likely to report large as opposed to small.

17) Do women value penis length or penis circumference more? - Circumference.

18) Does impotence/erectile dysfunction negatively impact sexual/nonsexual satisfaction? - Yes.

19) Does height correlate with penis length? - Not really.

20) Does hand size correlate with penis length? - No.

21) Does shoe size correlate with penis length? - No.

22) Does weight/BMI correlate with penis length? - Undetermined, but not likely.

23) Do gay men have larger penises than straight men? - Probably not.

24) Does penis size influence personality? - Maybe.

Data Analysis and Interpretation

1-5) I based these answers off the largest and most reliable study I could find, a systematic review performed in 2014 that developed nomograms for penis size and length based on up to 15,521 men. A nomogram is a graph that informs medical professionals what the general “norm” or average for a selected measurement is for the general population. In this case, the nomogram attempted to establish what the “normal” or “average” penis size of adult males in the general population is for five key measurements: Erect length, flaccid length, stretched flaccid length, flaccid circumference, and erect circumference.

This data is valuable for medical professionals who are counselling male patients on male anatomy, which might arise, for example, if a man wishes to undergo a penis enlargement procedure, in which case the physician could determine whether the patient is a good candidate based on how he compares to other men of similar age, race, etc., and then inform the patient of how he compares to general averages in case this information was unknown to the patient.

A systematic review is a type of clinical study in which a very large sample size is analyzed by compiling and comparing the results of many smaller studies. For example, a systematic review might include roughly 100 studies that each had included about 150 participants, which allows for an analysis of data on around 15,000 data points as opposed to just 150 in any of the smaller individual studies. The goal of this process is more or less to compare data that has been reported from various studies to see if there is any variation between them, and, if so, why that variation exists. One study of 150 participants might suggest that the average penis length is 7 inches when erect, but if 99 other studies of 150 participants each find results that are around the 5.5-6.0 inch range, then this provides a far better estimate of the actual average than the one study that reported different results.

This is why I chose this particular study to base my average penis size references on, as it is a large sample size that compares many different types of studies from all around the world, as opposed to a handful of studies from just one area of the globe. The averages that I mentioned are likely the closest known values to the true average. This study was also helpful in analyzing data on topics other than just penis length and size, and I would highly recommend this study as a point of reference based on its large sample size, high credibility, thorough peer review, and diversity of subject matter discussed within it.

6) I only decided to include this data point that is specific to U.S. males because it’s where I live and I happened to find it while researching this topic. The sample consisted of 1,661 male participants from the United States. It’s a relatively large sample size that is comprised entirely of one geographical population (U.S. males), which is often difficult to find, especially in smaller countries. I didn’t like, however, that the standard deviation in this study (stats jargon that I don’t care to explain here for sake of brevity) suggested that around half of the sample size fell within a range of about 4.5 inches to 6.6 inches, which is a rather broad range. This suggests to me that, while the “average” U.S. male penis length was reported to be about 5.5 inches, that the actual measurements were highly variable. The data even includes measurements as low as 1.6 inches and as high as 10.2 inches, which are so far outside the average range reported by other studies that it seems unlikely that so many male participants in this study were within the 5% of the population expected to have these measurements. Something seemed strange about these standard deviations and wide ranges of reported data to me, and I suspect that the process of recruiting individuals to participate in the study suffered from some sort of bias surrounding either its selection criteria or promotion to likely/potential participants. For example, it would be easy for someone to be aware of this study as it was taking place and suggest to a friend or patient or family member or whatever that they should participate specifically because they believed their penis size to be abnormal, which leads to recruitment of participants that result in high numbers of outlying data points, and thus skewing the data, as well. I’m not suggesting that this is what happened, but simply giving an example that would explain what I feel is an exceptionally varied data set.

7) Several studies and surveys have focused on female preference of penis length, but not all of them were conclusive or even recorded specific measurements. For example, some studies simply asked whether a “long”, “short”, or “average” penis length was most desirable, but this provides a relative reference and not a specific measurement. In general, however, women tended to prefer “average” penis lengths, or at least what they perceived as average in some cases, with many women even preferring smaller penis lengths for various reasons or for specific circumstances. One survey noted that several women specifically stated that smaller penises were desirable for oral or anal sex. Another survey found that women tended to prefer longer penises for “one night stands” and more average length penises for longer, ongoing relationships, perhaps suggesting that women enjoy sexual experiences with partners who have longer penises to some degree, but that the idea of frequent intercourse with a partner of above average length may grow tiresome, or even painful, over time. This also suggests that women are perfectly satisfied having sex with men of average or even below average length, and only really may prefer a longer penis as a “novel” experience if given the opportunity.

8) Again, this topic led to similar results as the previous topic. Women tend to prefer men with penises that are, to put it simply, totally average. There was hardly any skew one way or the other to suggest otherwise. Also, as in the previous topic on preferred penis length, most surveys or studies didn’t record specific measurements. Measurements were likely avoided on purpose in many cases solely because it can be difficult to verify the accuracy of the measurements. For example, if you asked 1,000 women to name their preferred penis length in inches without handing them a ruler or giving them a reference to what their partner’s penis length actually is, then most women are probably not going to give a reliable or accurate estimate off the top of their head. Many women might state that 6 inches is their preferred length, when in reality their partner’s penis might only be just over 5 inches long and they are simply under the impression that it is longer. Basically, without having actual physical references for women to base their estimates off of, or actually taking measurements of their partners’ penis lengths, then there’s no really reliable method of determining what the specific preferred length really is. I do talk a little more in-depth about this in question #9, however, about how attempts have been made to get a more accurate estimate without taking such drastic measures as literally measuring men’s penises to verify the accuracy of their wives’/girlfriends’ estimates, and the method developed to do this was actually rather clever.

9) A study of women's perceptions of attractiveness of nude male figures found that women were more likely to rate figures of similar body height/weight as more attractive if the figure had a larger penis. In other words, when shown two similar sized nude male figures, women rated the figure with the larger penis as more attractive. However, figures with larger-than-average penises were actually rated as less attractive than those with average or slightly below average penis sizes. This suggests that women actually consider males with average or slightly below average penis lengths to be the most attractive, creating a sort of "curve" of attraction levels with penises that are significantly smaller or larger than average considered the least attractive and penises of a relatively average length to be considered the most attractive. What is interesting is that there seems to be a sort of "relative penis size" preference that favors men with larger penises, but this is not reflected in the overall data to indicate that generally large penises are more attractive. It's sort of hard to explain this one because of how complex it is, but think of it like this: Women are shown various mannequin-like figures of nude males in no particular order. The figures vary drastically in height, weight, musculature, and penis length, but all other factors remain the same. They are asked to rate the attractiveness of each male figure and the results are compared. The figures with exceptionally small or large penises were rated poorly across the board, but figures of similar height/weight/musculature were rated based on their penis length. The results might look like this if the attractiveness scale was from 1-10:

Group A

6ft, muscular, thin, 7" penis - 6.9

6ft, muscular, thin, 6" penis - 10

6ft, muscular, thin, 5.5" penis - 9.7

6ft, muscular, thin, 5" penis - 9.3

Group B

5ft, muscular, thin, 7" penis - 7.2

5ft, muscular, thin, 6" penis - 9.2

5ft, muscular, thin, 5.5" penis - 8.7

5ft, muscular, thin, 5" penis - 8.1

Group C

6ft, non-muscular, thin, 7" penis - 7.3

6ft, non-muscular, thin, 6" penis - 9.1

6ft, non-muscular, thin, 5.5" penis - 8.8

6ft, non-muscular, thin, 5" penis - 8.6

Group D

5ft, non-muscular, overweight, 7" penis - 3.2

5ft, non-muscular, overweight, 6" penis - 5.1

5ft, non-muscular, overweight, 5.5" penis - 4.7

5ft, non-muscular, overweight, 5" penis - 3.9

From this set of data (that I totally made up for sake of explanation), it is pretty easy to see a trend emerging, which is similar to what happened in the aforementioned study, but was exaggerated here to make this point more easily understood. All of the 6ft, muscular, thin males of Group A were rated as very attractive in this mock sample with the only difference being seen in their relative penis size. The well above-average penis length of 7" performed the lowest in this group, while the average to slightly below average penis lengths performed the best. In Group D, the 5ft tall, non-muscular, overweight males received the lowest ratings of all the groups, but again, even in this group the worst rating was the abnormally lengthy penis, while the best ratings in this group were assigned to the males with average-ish penis lengths.

This is very similar to what happened in the study that I based this mock data on. The taller, more muscular, thinner male figures tended to score the highest of all the figures, but the lowest ratings among these figures were assigned to males with penis lengths outside the average range. A similar trend appeared among the shorter, less muscular, more overweight male figures. These figures received the lowest ratings, in general, but even within this group the figures with average penis lengths performed the best.

This study was actually very intriguing to me because it seems to suggest that as women consider many factors that make a male attractive, penis length actually does come into consideration, but it isn't the factor that carries the most importance. This study seemed to suggest that women tend to first attribute attraction based on body size factors like weight and height, and that they tend to really only use penis size as the determining factor between otherwise very similar male figures. In other words, it suggests that women are much more likely to rate a tall, muscular, thin male with a small penis as being more attractive than a shorter male with less muscle who basically has the ideal penis length. It sort of shows how very little the influence of penis size is on female attraction levels.

Please see part 2 of this MyTake for continued analysis and discussion. Thank you.

    This was quite an interesting read, and I'll look forward to reading part 2 more closely as well (sorry for commenting on 2 before reading the whole post).

    "and I would highly recommend this study as a point of reference..."
    What's the name of the study? If you said, I missed it.

    In the example data set for female attraction, it goes 7", 6", 5.5", 5".
    You say average or slightly below average performed the best, but if 6" is slightly above average and scores better than 5.5", then I wonder where the missing 6.5" places, and where the maximum values were.
    It's interesting to know that height and build played such a big factor. Height's effects may lead to further body insecurities among men due to being gene-based, but build having measurable effect may give them something to work on.
    Is this still revelant?
    • Aplogies for the missing studies. I lost them in the upload process. I believe this is the one I was referring to:

      onlinelibrary.wiley.com/doi/full/10.1111/bju.13010

      In the part about the sample set... Well, that's highly exaggerated compared to the study, but I only did so because I was probably underestimating the general comprehension level of the average reader more than I should have. Regardless, it's still pretty complex and doesn't play out to such extremes as in the sample set I've provided. I believe this is the study that I was referencing when creating that sample set, though there was more than one that used a similar method of 3D male models to compile similar data sets:

      www.pnas.org/content/pnas/110/17/6925.full.pdf

      Here's one of the similar studies, as well, I believe:

      Thank you for your input, and sorry for the delayed response... Got a lot going on right now, haha

  • TadCurious
    Thank you very much for writing and posting this. It was very interesting and (as someone with an average size penis) reassuring.
    I'm going to read Part 2 shortly.
    I do have a question about item 6) under Data Points Analyzed. That item reads "Average erect penis length, U. S. males, pendulous: 5.57 inches"
    My question is how can an erect penis be pendulous? By definition it seems like an erect penis is the opposite of pendulous, but maybe I'm not understanding the use of that term in this context.
    Anyway, thank you again for this very well written and researched myTake. It's the most definitive post on this topic I've ever seen on this site. 👍👍👍
    Is this still revelant?
    • Apologies, and good find. That was a typo, I believe. I believe upon reviewing it that it was intended to read "average erect penis length, U. S. males". I think I was trying to write a section for "average erect penis length, U. S. males" and "average flaccid penis length, pendulous, U. S. males". I had a bit of trouble getting the posts to the correct length to upload and had to cut a sizable portion of this in the editing process, and most likely overlooked this error. Thank you for pointing it out.

      Also, thank you so much for the flattering comments! I'm glad people on here are enjoying this sort of thing... I thought it was going to be hated. "Too technical, too long," was the type of thing I expected, so thank you for the reassurance that people are enjoying it!

    • TadCurious

      I wasn't trying to be picky. I just thought maybe I was missing some particular nuance of "pendulous."
      You do have a great talent for taking studies and difficult statistics and distilling them down for the lay reader. I know this 2-part myTake was a lot of work, but I do hope you'll do more in-depth pieces like this as you get the time in the future.
      Thank you again.

    • No worries @TadCurious, I wasn't under the impression that you were trying to pick anything apart. I do appreciate when someone points out my typos, though, so thanks again. Helps me improve, and to be aware of potential confusion from other readers.

      Also, thank you so much for your kind words! I do love writing, and yes, I do intend to do more of these... I'm just not sure exactly when I'll have the time. My schedule can fluctuate on occasion, especially if I accept more speaking engagements or pursue more "professional" writing opportunities, but I do hope to find time for the GaG community that I've come to know and love so much recently! You guys are awesome!

    So, basically you’re saying women like long big penises. But, prefer short small ones for relationship reasons.
    Is this still revelant?
    • Haha, well, it's not THAT simple. There's something to be said about that particular survey result, for sure, because it was the only one that I found that reported it that way, but I don't think it was whether or not they "preferred" it, necessarily, but more like, "might want to try". Either way, the majority of women were happy just with the average length and size. I can't say I didn't expect that.

  • Jersey2
    My flaccid penis length and girth varies by a lot from micro to well hung depending on temperature and level of excitement as some excitement adds blood but not enough to make it erect. My erect length and girth varies as well depending on level of excitement. It’s a bit of a moving target as far as precise measurements go.

    I read a study that showed that someone with an 8 inch penis was more likely to be gay.
    • The study about men with longer penises being more likely to be homosexual was likely the analysis of a subset of data from a Kinsey Institute study, and it has since been held inaccurate and misleading by most of the medical community.

      As far as size varying with temperature and level of excitement and such... Well, this was a bit of an issue in some studies, but the solution is hypothesized to be in the "stretched flaccid length", or the length of the flaccid penis stretched to its full length by pinching the head of the penis and pulling to its full length. This has proven the most consistent measurement across studies, but also from one measurement to the next with the same individual.

    Here's the answer, some women are never satisfied.

    Case in point , purchase of sex toy sizes increase as exploration increases, and self freedom increases.

    You wonder why for some, pussy rejuvination is now so popular lol

    You want to spend the time , pound the well, you must expect some change, new character happen to your Jay Jay lol

    Don't complain, when your pussy more warn out then watching a Sam ramey movie lol

    I got jokes for days and days lol jk

    In seriousness , the truth is , as a man I who observes douchie, cattinesses of some women think their pussy be all that glitters is not in fact gold.

    If women is so obcessed with her pussy alone. that she doesn't see the other person's side, she does not alone room for mutual pleasure or discussion.

    Any women has the right to refuse any advance.

    But you have no right to be straight nasty because one can.

    This obcessive need to fuck the best, blow and lick the best.

    What are we training for the sex Olympics lol

    Some people damn well lost perspective of life and society.

    Sex is only minor pillar in human system of existence.

    If you think it's the primary key , you may be a sex addict or porn star, or deviant.

    Love is a pillar this generation is primarily erroding , one blind thrust, poke, lick, suck, and blow.

    Spend your days creating , speaking, honesty, devise more common sense.

    Just because you have free will, you literally screw yourself out of potential outcomes because you focus on nutting, clit orgasms, g spot squirters, anal play, BJ's.

    Pleasure isn't entirely, wrong but society, social nuiances happen and cause, effect , cost happen not singulary but multi variably to many.

    Wake up , do your selves a favor learn to hone common sense, before blindly bumping uglies lol

    If your obcessed with your dick giant or medium, small, your missing the true nature of why you exist.

    Perspectively, I've mastered what most can never do.

    Hone my sexually power, common sense, intellect.

    I'm not saying don't have pleasure, don't be so stupid just blindly fucking every person that comes your way.

    You'll grow numb, un able to find or define real love or reality life.

    Just be wise, rapp your stuff and be kind to one another , don't be selfish.

  • Billygee6969
    There are small and large but whether you have either is not what determines whether you please her, it's what you do with it. The fact that you think size determines good or bad sex. And yes a very small one is not good but there so many other things that go along with the act. I woman has wants, needs, and desires and you are not going to fulfill all of them with your penis. I feel sorry for young women because they have to deal with young men, they are only worried about getting theirs , but they will act like they were the greatest thing since slice bread, and will ask but women who love their men will lie. I was taught young by an older neighbor beauty about what makes a women tick, and no I wasn't abused, I was just bigger for my age and was thought to be older. She said just take your time and learn and watch how she reacts when you do certain things. It has been something that I prefer to do , for as long or as much as she needs. Be romantic, and consider her, believe me you will be rewarded far more than you could ever imagine. Hugs kisses and looking into her eyes. And every morning when you wake up pull her close, tell her how beautiful she is, how much you love her , and how blessed you are that she has chosen you to spend her life with.

  • esotericstory
    I dont think men want a bigger penis because of women. I think men want a bigger penis for themselves.
  • wagsingle

    For some men, being obese does impact effective penis size. It depends on where their fat is. I met a guy whose penis barely made it past his balls.
    • This was a problem for most studies I found, not necessarily the obesity issue, but the fact that there wasn't much of a mention of how the measurements were taken. There's two primary methods of measurement, both of which, as it turns out, struggle to be duplicated within a reasonable degree of accuracy from one measurement to the next. Basically, it's under versus over when measuring in most studies, as in "pubis to glans head" versus "scrotal fold to glans head", or "belly to tip" versus "balls to tip".

  • Cannuck22

    Good for you to taking a few days to write that all up but it’s all for nothing.
  • October808
    Interesting. So this leads to a hypothesis that fat girls say size matters because their fat layer doesn't allow for anything than bigger than average penises.
  • Massambit
    Looking at the last study one would have to conclude women find tall men more attractive generally speaking and prefer a six inch erect penis.

      It's not a bad thing. I was just making an observation.

    • To be fair, I'm "very into" anatomy and physiology as a whole... Dicks just happen to be a particularly intriguing and comical portion of that subject, along with vaginas and anuses. All quite humorous to read actual "professional" medical literature about since we often don't think of them as being serious aspects of our anatomy and how they affect our mentality and outlook on life. It's usually like, "Haha, look, a weiner!" But in reality, there's a lot going on down there for both sides.
