The TSA Scanner Problem:
A BDP Guide to Airport Security
The Red Box, The Pat-Down, The Solutions
🔴 10 min read
Every time you fly, it's the same story. You step into the millimeter wave scanner, assume the position, and watch the agent's screen light up with a red box directly over your crotch. "Male assist!" they call out. Here comes the pat-down. According to data from r/bigdickproblems and travel forums, this happens to well-endowed men on approximately 66% of flights. The kicker? TSA knows their scanners have this false positive issue - they just don't care enough to fix it.
What TSA Agents See
GROIN ANOMALY DETECTED
This is what flags every single time
The Technical Problem
The millimeter wave scanners compare your body against what the software considers a "normal" male silhouette. The problem? That baseline doesn't account for size variation. When you stand with your feet spread in the required position, anything hanging more than their expected parameters triggers an "anomaly."
A 2014 government report acknowledged that the scanners have higher false alarm rates for various body types and characteristics. Former TSA agents have confirmed the technology isn't sophisticated enough to distinguish between actual threats and anatomical variations.
What TSA Knows But Won't Say
Multiple TSA agents on forums have acknowledged: "The body scanner is somehow detecting a dense area at your crotch... This is a PITA for TSA agents too." They know it's a false positive. They know it's your anatomy. They still have to do the pat-down because protocol requires investigating every alarm.

The Pat-Down Reality
What Actually Happens
When that red box appears, here's the process:
- Agent calls for "male assist" (drawing attention)
- You're directed to a screening area (sometimes private room)
- Agent explains they need to check the "groin area"
- They use back of hands for "sensitive areas"
- The awkward "Is this you?" question when they feel it
- Sometimes requires supervisor confirmation
- Gloves sent for explosive residue test
- Finally cleared after 2-5 minutes
"The TSA agent asked 'Is this you? Is this you?' when he encountered what could have been a bomb but was in fact genitals. None of the three men seemed reassured after the search either."
- Actual traveler experience from 2011
Why It Keeps Happening
The System Is Broken By Design
The scanners were updated to avoid showing "naked" images after privacy complaints. The trade-off? The software now has to guess what's normal anatomy vs. a threat - and it guesses wrong constantly. TSA chose false positives over accurate detection.
Additional factors that make it worse:
- Wide stance requirement: Makes everything hang loose and visible
- Autonomous processing: No human can override obvious false positives
- One-size-fits-all baseline: Software expects average anatomy
- Protocol requirements: Every alarm must be investigated
- No medical exemptions: Doctors' notes don't skip pat-downs
Other Things That Trigger It
Based on documented cases, the scanners also flag:
- Hernias and cysts in the groin area
- Sweat ("swamp crotch" creates density anomalies)
- Thick underwear or compression shorts
- Baggy pants creating fabric bunching
- Medical devices or implants
- Even slight arousal or "chubs"
The Discrimination Issue: Trans men and women face this constantly due to anatomy not matching the scanner's gender button. The ACLU has documented this as systematic discrimination, yet TSA continues using the flawed technology.
What Actually Works (Sometimes)
Strategies That Reduce (Not Eliminate) Issues:
- Compression shorts: Keeps everything tight and centered
- Pull pants up before scan: Reduces fabric bunching
- TSA PreCheck: Often uses metal detectors instead
- Opt for pat-down: Skip scanner entirely (your right)
- Boxer briefs over boxers: Less movement during scan
- Dark, thick dress pants: May reduce detection
What Doesn't Work:
- Doctor's notes (TSA doesn't accept medical exemptions)
- Explaining to agents (they have to follow protocol)
- Asking for rescan with different gender (new AI supposedly gender-neutral)
- Complaining (agents know it's broken, can't change it)
Your Rights
Important things to know:
- You can request a private screening room
- You can have a companion present during pat-down
- You can opt out of scanner for pat-down instead
- Pat-downs should be same-gender agent
- Agent must explain process before touching
- You can file complaints (though nothing changes)
International Comparison
Other countries have recognized the problem:
- France & Germany: Abandoned millimeter wave scanners due to false positives
- UK: Different technology with fewer groin anomalies
- Netherlands: Manual checks only after specific intelligence
- Japan: Metal detectors primarily
The US continues using technology that other nations deemed too flawed.
The Psychological Impact
What nobody talks about:
- The humiliation of being singled out repeatedly
- Other passengers staring and making assumptions
- Partners/colleagues witnessing your pat-downs
- Missing flights due to secondary screening
- The anxiety before every flight
- Being treated like a criminal for your anatomy
"I travel very often, and nearly every time... a yellow box appears on the screen over my penis. Not only is it uncomfortable to have someone touch me in personal areas every time, but it's also very time consuming."
- Common BDP experience
The Bottom Line
The TSA millimeter wave scanners have a known false positive problem with larger anatomy. TSA agents know it. The government knows it (per their own 2014 report). They continue using the technology anyway because the alternative - accurate body imaging - was deemed too invasive for privacy.
So we're stuck with a system that flags penis size as a security threat, wastes everyone's time, and humiliates travelers - all security theater that catches zero actual threats while harassing people for their bodies.

Practical Travel Tips
For Your Next Flight:
- Arrive 15 minutes earlier than normal (for pat-down time)
- Wear compression shorts or tight boxer briefs
- Consider TSA PreCheck ($78 for 5 years)
- Empty pockets completely (any anomaly triggers closer inspection)
- Stay calm during pat-down (agents are just doing their job)
- Consider opting out preemptively if you always trigger
The One Silver Lining
Multiple travelers report that once agents realize what triggered the scanner, they become apologetic and try to expedite the process. Many are embarrassed by the false positive and handle it professionally. The system is broken, not the people operating it.
