Why Urologists Say “Think Twice” Before DIY Urethral Play: Science-Backed Advice for Safer Sex Play

A shocking case, the real risks of urethral sounding, and practical tips to keep your sexual health—and curiosity—in check.

Ever Heard the One About the Man Who Used Spray Foam—Down There?
As a urologist and pelvic surgeon, I’ve seen a lot. But nothing surprises me quite like the inventive (and risky) ways people explore their bodies in search of pleasure. Few stories illustrate this better than the case of a man who ended up in the ER after filling his urinary tract with insulation foam. Yes, really—and there’s much more to the story.

If you value sexual well-being and are curious (or concerned) about how to safely explore your own body, this is for you. Let’s dive into why the right knowledge, not household items, is your best tool for pleasure—and health.

Why This Matters: Pleasure, Curiosity, and the Real Risks

Urethral sounding—intentionally inserting objects into the urethra for sexual gratification—is more common than many realize, often shrouded in stigma and silence. Unfortunately, what should be steeped in caution is too often rooted in improvisation with everyday items: pens, straws, and, in one recent extreme, spray foam.

The Problem?
Urethral trauma can lead to serious complications including:

• Urinary tract infections

• Bleeding and pain

• Scar tissue or "stricture disease" (narrowing of the urethra)

• Urinary retention

• The need for complex surgical removal of foreign materials

In the spray foam case, the patient “sounded” with the tiny straw from the can—never intending to activate the foam. But an accidental press of the button released insulation into his urethra and bladder, causing severe blockage and requiring surgical removal. Yikes.

What Urologists Really See: Lessons from the Clinic

From my own experience and that of my colleague Dr. Susan McDonald (the case’s reporting physician), here’s what gets found in the ER:

• Household items: pens, pencils, paintbrushes, beaded keychains, toothbrushes

• Magnetic balls (“Buckyballs”)—which can coil or get stuck, compounding removal difficulty

• Straws and other makeshift objects

The common thread? Most of these items lack any sort of flared base and are easily “lost”—meaning they slide deeper, often into the bladder, where DIY removal becomes impossible.

Safe Exploration: What If You’re Curious?

I get it—sexual curiosity is healthy and normal. If you choose to engage in urethral sounding, here are the safety essentials:

• Use Medical-Grade or Specialty Toys: Opt for surgical-grade, single-use catheters or sounds with flared bases. These are specifically designed to avoid getting lost inside.

• Sterility is Key: Wash hands thoroughly; use single-use sterile lubricant packets to minimize infection.

• Gentle Insertion Only: Let gravity do the work. If you feel any resistance, stop immediately—never force objects in.

• Prefer Silicone Over Metal: Especially for beginners. Silicone is flexible and less likely to cause trauma or injury if you veer off course.

• STOP at Any Sign of Pain or Bleeding: If something feels wrong, it probably is.

• Know When to Seek Help: Difficult urination, pain, or anything ‘stuck’ warrants an immediate visit to a friendly, judgment-free urologist.

What Happens If Things Go Wrong? (Real-World Example)

In our headline case, the man waited three days before seeking help. By then, foam had hardened and cast itself inside his urethra and bladder—then requiring major reconstructive surgery to remove it.

Symptoms of Urethral Stricture Include:

• Weak urinary stream or increased time needed to pee

• Difficulty starting urination

• Frequent urges or incomplete bladder emptying

If you notice these red flags—or have a memorable bathroom episode (like outlasting everyone at a sporting event urinal)—don’t ignore it. Get checked out. Many causes are treatable when caught early.

Urologist-Recommended Resources and Practices

What to Do Instead:

• Use only body-safe, sterile toys designed for urethral play (available at reputable sex toy vendors)

• Always prioritize hygiene and sterility

• Talk openly with your provider about your interests—they’ve seen it all and their only goal is your health
