I finished. Shook. Checked. Dry. Zipped up, walked back to my desk. Two minutes later, a cold patch, right where it absolutely should not be.

For a long time I assumed this was just me, some private failing I had to manage quietly. It is not. It is a specific, mechanical event with a name, a cause, and a fix that takes about five seconds to learn. The only reason most men never learn it is that nobody brings it up.

What Is Actually Happening

It turns out this is almost reassuringly mechanical. The urethra curves upward behind the scrotum, in a section called the bulbar urethra. When you void, the main stream clears most of that tube, but a small pool of urine is left sitting in the curve. It does not come out during normal voiding. The moment you move, gravity and the motion of walking shift it forward and out. Hence the patch.

This is post-micturition dribble, usually shortened to PMD, also called after-dribble. It is common, and it gets more common with age: estimates vary a lot depending on who is counted, but this is a large slice of men, not a rare few (Yang and Lee, 2019).

PMD is not urgency incontinence, which involves the bladder contracting at the wrong moment. PMD is a small drip that happens after voiding is finished, with no urgency involved. It is also distinct from terminal dribble, which is a weak end to the stream itself, still at the toilet. NICE quality statement 5 puts it plainly: urethral milking eliminates PMD caused by incomplete emptying of the urethra by the surrounding muscles, rather than by obstruction.

Why Nobody Mentions It

Men assume PMD is just them. It does not fit neatly into the standard clinical categories. NHS urinary incontinence guidance is built around stress, urge, overflow, and total incontinence. PMD sits outside all of them. It is mechanical and anatomical: a curve in the urethra, a small muscle that did not quite fire, a pool of urine with nowhere to go until gravity found it a route.

So men manage it privately. Folded tissue, double-checking clothing in mirrors, choosing darker trousers, carrying a low hum of background anxiety, all without knowing the cause, without knowing the fix, and without knowing how many other men are doing exactly the same thing.

Urethral Milking: The Technique That Works

The fix is called bulbar urethral massage, also known as urethral milking. It clears the pooled urine out of the bulbar section before you dress. NICE recommends that men with PMD are shown how to do it by a healthcare professional. In practice, most men with PMD have never been offered it.

The method, as described in NHS Trust patient leaflets, is:

The Pelvic Floor Connection

At the moment the stream ends, a firm pelvic floor contraction acts as a natural pump, squeezing the muscle around the bulbar urethra and helping to push out the last of the urine. In one trial, men who did pelvic floor work alongside lifestyle changes mostly cleared the problem: about two-thirds were dry by three months and four-fifths by six, against almost none of the men who changed lifestyle alone (Dorey et al., 2004, in men who also had erectile dysfunction).

Bulbar urethral massage and pelvic floor training tackle the same underlying mechanism from different angles. You can use both together for maximum effect.

When Products Help

For men where technique alone does not fully resolve things, a drip collector, also called a penile pouch, is a small shaped absorbent pouch designed to fit over the glans and catch the specific small volume associated with PMD. Small shaped pads or pouch-style liners are an alternative. The key principle: choose the lightest appropriate product. PMD is a small-volume event. Heavy absorbent pads meant for larger-volume incontinence are both unnecessary and less comfortable.

When to See a GP

See a GP if you notice:

These can indicate prostate enlargement, a urinary tract infection, or other conditions that need clinical assessment.
