Jonah Falcon aroused suspicion when eagle-eyed guards from the Transport Security Administration at San Francisco International Airport spotted his bulging package.
The well endowed New Yorker was thoroughly searched and even had powder sprinkled on his pants to check for explosives after his “very noticeable” manhood was mistaken for a biological threat.
Mr Falcon told the Huffington Post: “I had my ‘stuff’ strapped to the left. I wasn’t erect at the time.
“One of the guards asked if my pockets were empty and I said, ‘Yes.’ I said, ‘It’s my d***.
“He gave me a pat down but made sure to go around [my penis] with his hands.
“They even put some powder on my pants, probably a test for explosives. I found it amusing.”
Mr Falcon is considered to have the world’s largest penis, although the Guinness Book of World Records does not record such achievements.
His manhood, which has even featured in a documentary, measures 9 inches limp and 13.5 inches when erect.
His huge crown jewels have made him a minor celebrity, as he has featured on numerous talk shows in the US and has been approached to do porn, but has never accepted.
Despite his interrogation, Mr Falcon managed to see the funny side, adding: “I’m just going to wear bike shorts from now on.”
Officials from the Transport Security Administration have not yet commented on the incident.
