Male squirting is a forceful expulsion of fluid from the urethra that occurs separately from ejaculation, typically when penile stimulation continues after a man has already climaxed. Unlike ejaculation, which releases semen, the fluid expelled during male squirting is primarily urine that gets pulled from the bladder through a specific sequence of muscular contractions. It’s a real physiological event that has been documented and studied with ultrasound imaging, though it remains poorly understood and rarely discussed.
How It Happens
Male squirting follows a precise chain of events inside the body. After ejaculation, if stimulation of the penis continues, the prostate and the muscles of the pelvic floor begin contracting strongly. These contractions cause the section of the urethra that runs through the prostate to widen dramatically, a process researchers describe as “ballooning.” That sudden expansion creates a vacuum-like effect that draws urine down from the bladder through the bladder neck and into the dilated urethra.
Once enough fluid has accumulated, successive waves of contraction from the prostate and pelvic muscles push it outward. At the same time, the urethral sphincter (the valve that normally holds urine in) relaxes, while the bladder neck clamps shut. This means fluid can only travel in one direction: out. The result is a rhythmic, forceful gush of fluid from the tip of the penis. After the episode ends, the bladder neck reopens, the prostate returns to its normal shape within about 30 seconds, and the anatomy resets.
Color Doppler ultrasound imaging has captured this process in real time, showing the fluid stream moving rapidly from the bladder through the prostatic urethra just before expulsion.
How It Differs From Ejaculation
Ejaculation and male squirting are two separate events involving different fluids, different triggers, and different timing. Ejaculation happens at the point of orgasm and releases semen, a mixture of sperm and secretions from the prostate and seminal vesicles. Male squirting happens after ejaculation, only if stimulation keeps going. The fluid is not semen. It’s dilute urine that the body pulls from the bladder through a specific muscular mechanism.
The volume of fluid can also be noticeably larger than a typical ejaculation. While the average ejaculate is roughly 2 to 5 milliliters, the gush produced during male squirting can be substantially more, which is part of what makes it visually distinct and sometimes surprising for people who experience it for the first time. The sensation is also different: rather than the pulsing contractions of orgasm, the experience involves a sudden, involuntary release of fluid that may or may not be accompanied by additional pleasure.
The Connection to Female Squirting
The parallel with female squirting is more than superficial. The female prostate, historically called the Skene’s gland, develops from the same embryonic tissue as the male prostate. Both organs share similar structure, function, and chemical markers. Both produce prostate-specific antigen (PSA), and both contain androgen receptors that influence their growth and function. Studies of female squirting have similarly found that the expelled fluid is largely dilute urine, sometimes with small amounts of prostatic secretions mixed in.
In both sexes, the phenomenon appears to involve intense muscular contractions that override normal urinary control in a specific, patterned way. This shared anatomy helps explain why the experience looks and feels similar regardless of sex, even though the surrounding reproductive structures are quite different.
What Triggers It
The key trigger is continued stimulation after ejaculation. For most men, the period immediately following orgasm involves heightened sensitivity of the penis and pelvic region. If stimulation persists through this hypersensitive window rather than stopping, the prostate and pelvic muscles can enter a pattern of strong, repeated contractions that sets off the chain reaction described above.
Prostate stimulation, whether external through the perineum (the area of skin between the genitals and the anus) or internal through the rectum, can also intensify the response. The prostate sits about an inch inside the rectum toward the front of the body and can be located as a round, walnut-sized bulb of tissue. Massaging it with a gentle, curling motion of the fingertip along the front wall of the rectum is the most commonly described technique. Some people find that combining prostate stimulation with continued penile stimulation after ejaculation makes the response more likely.
Is It Urinary Incontinence?
People who experience male squirting sometimes worry that they’re losing bladder control. The two things are mechanically different. Urinary incontinence involves involuntary urine leakage due to weak or damaged sphincter muscles, nerve problems, or bladder dysfunction. It can happen during coughing, sneezing, physical activity, or with a sudden urge to urinate, and it’s not tied to a specific sexual sequence.
Male squirting, by contrast, follows a very specific pattern: it only occurs after ejaculation under continued stimulation, and it involves coordinated, strong contractions of the prostate and pelvic floor muscles rather than weak ones. The bladder neck actively closes during the event, which is the opposite of what happens during incontinence. The sphincter relaxes in a controlled way as part of a muscular sequence, not because it has failed. If you’re only experiencing fluid release in this specific sexual context, that’s a different situation from incontinence that occurs at random or during non-sexual physical activity.
How Common Is It?
There are no reliable prevalence numbers for male squirting. The published medical literature is extremely limited, with the most detailed study being a single case report analyzed with ultrasound imaging, published in the journal IJU Case Reports. The phenomenon is almost certainly underreported because many men who experience it either don’t mention it to a doctor or assume it’s simply post-orgasmic urine leakage. The stigma around any fluid release that might be urine adds another layer of silence.
What the existing research does confirm is that male squirting is a real, documentable physiological response with a clear mechanical explanation, not a myth or a performance. Whether it’s rare or simply rarely discussed remains an open question.
