Every man remembers the first time he measured himself

You know where you were.

A bedroom or a bathroom, with the door locked or wedged, or else you'd listened for footsteps first. The ruler was a school ruler, thirty centimetres, probably transparent, probably chipped at one corner. Or a tape measure borrowed from a drawer downstairs and put back before anyone noticed.

You were eleven, or fourteen, somewhere in there. Nobody had told you how to do it, so you improvised a method on the spot, and you've quietly wondered ever since whether you did it right.

Then you got a number. It went in and it stayed, and I'd bet a lot that you could say it out loud right now, faster than you could produce your own bank card PIN.

I want to talk about that boy. The whole adult architecture of this anxiety got built during the ten minutes he spent alone with a piece of plastic, and nobody has been back for him since.

What he did not have

Think about what that kid was working with.

No reference distribution, for a start. He didn't know the mean, he didn't know the spread, and he had no idea that the figure he'd just produced was a single draw from a population nobody had ever described to him. A thirteen-year-old with a data point and no denominator.

He also didn't know he was measuring a body that was not finished. Genital development runs on its own schedule, varies wildly between boys, and tends to complete some years after most boys have already filed their verdict. He measured a construction site and read it as a finished building.

Then there's method. From the top? Pressed in? Along the top, or underneath? Stretched or not? Each of those choices shifts the number by something comparable to the entire difference he was frightened of.

And there was nobody to ask. Not one person. That's the part that gets me. In most other areas of adolescent panic, a lump or a rash or a worry about growth, there is at least a theoretical adult somewhere. Here the adult was structurally unavailable, both parties knew it, and both parties were relieved.

Sixty-seven men and a waiting room

In 2002 a group of Italian urologists under Nicola Mondaini did the obvious thing nobody had bothered to do. Men kept turning up at their clinic in Florence asking to be surgically lengthened, so the team measured them: all 67, flaccid and stretched, against the reference ranges.

Not one was short. Not one had any anatomical abnormality at all. Sixty-seven men, median age 27, had walked into a hospital to ask a surgeon to cut into the most sensitive part of their body, and every one of them was already normal.

I've read a lot of studies for this site and that one still knocks the wind out of me, because those aren't statistics. They're sixty-seven separate Tuesday afternoons. Sixty-seven men who booked the time off, sat in a waiting room rehearsing how to say it, and had probably spent years working up to the appointment, all of them carrying a false belief about their own body that a thirty-second measurement could have corrected at any point in the preceding fifteen years.

Somebody could have told them. Nobody did. I don't think that's a medical failure so much as a cultural one, and we are all shareholders in it.

The finding that should be on a poster in every school

Twelve years after Mondaini, David Veale's group built the first validated instrument for measuring this particular shame, the Beliefs About Penis Size scale, and published it in The Journal of Sexual Medicine.

It worked as designed. Scores correlated with depression, with anxiety, with social anxiety, with body-image quality of life, with erectile difficulty and with overall sexual satisfaction. Every one of those relationships came out significant, which tells you the shame is neither trivial nor vanity, and that it does measurable damage to real lives.

Then there's the one correlation the scale did not find.

What we actually did to that boy

Angry paragraph coming. I'll calm down after it.

We handed a child a lifelong metric for his own adequacy, gave him no baseline, no method and nobody to ask, then filled the surrounding decade with jokes. Locker-room jokes, sitcom jokes, jokes in adverts, jokes from adults who knew better. All of them encoding the same message: this is a thing men are ranked on, and being at the bottom of it is the funniest available outcome.

We wouldn't do this with any other body part. Nobody makes a punchline of a child's height while he is still growing. We don't, as a culture, agree to laugh specifically at whoever is smallest. And where we do get it wrong, with weight or acne or height, there is at least a counter-movement somewhere: a language of body acceptance, a school policy, a book someone wrote.

Here there is nothing. No body-positivity movement, no ad campaign, barely a vocabulary. What exists is a multi-billion-dollar industry selling pills to men who are already normal, plus the jokes, plus silence in between. That is the entire cultural provision.

The thing I'd tell him

If I could get a message back to that kid with the school ruler, it wouldn't be a reassuring number. He wouldn't believe a number, and nobody does; that's the finding. It would be four things instead, all of them boring, which is the point.

That the body he was measuring wasn't finished, and measuring an unfinished thing tells you very little.

That the method he improvised probably wasn't the method the studies use, and the gap between methods is wider than the gap he was frightened of.

That the number in his head came from surveys of men who were guessing, and that when clinicians measure actual men the figure comes out lower, and the spread comes out much wider, than anything he had heard in a playground.

And that in twenty years or so, a great many of the men he was measuring himself against would turn out to have done exactly the same thing, alone, in a bedroom, with the door wedged shut. None of them would ever mention it either.

That's the part I find saddest, and I don't think I'm overstating it. Millions of boys, across generations, each one privately convinced he was the only person running the experiment.

He was never the only one. Statistically, he was almost everyone.
