Going all the way back to 1980's, when I would try to go out and socialize, I, and a buddy or two, would go to various nightclubs on Friday or Saturday nights. There would be a police officer, often two officers, hanging around the front doors of the nightclubs, acting as security. They see my bulge, and they even shine their flashlight beam on my crotch. They approach me, and in a stern tone of voice say to me, "Excuse me, Sir, we are checking for drugs. Would you mind opening your pants?!" I would comply. The officers would briefly stare at the bulging of my underwear, then look at each other, stare at my crotch again, look at each other again, then back to the bulge, like they didn't know what to do next. Early on I decided to set it straight, and satisfy any curiosity they have about what is causing the large bulging in the crotch portion of my pants. As soon as I get the pants opened, I grab the waistband of my underwear, pulling it forward and just-slightly downward enough that the officers can look down into, directly at my anatomy. (It's a silent, "You want to see what's causing the giant bulge in my pants? Okay! Fine! Here, HERE!, THIS is what is causing the giant bulge in my pants! See it? Are you happy now?")
In the words of one cop, "Christ! It really is his penis!"
Nightclub doormen/bouncers also point at my crotch and say, "Excuse me, Sir, but I have to check you for drugs, please open your pants. I pull my underwear open for them too.
One day there were two police officers inside the door of the nightclub, standing near the doorman. I think the doorman was nervous about the cops, and wanted to make sure he was doing his job of searching potential drug dealers. He looked at the cops then did the "Sir, I need to check you for drugs" routine on me. I think I wasn't careful enough about how my body parts were positioned in relationship with how my clothing fit. I was looking at the cops when I pulled the waistband of my underwear out and slightly downward for the doorman to see the top of my penis laying across my left thigh, and over my left testicle, I pulled a little too much. My penis came tumbling out over the top of the waistband. About nine or ten people including the two police officers watched as my stupid, freakshow giant dick went flopping out over my pants to become draped over my testicular (scrotum) bulge which was still covered by clothing. Hanging out as if I was naked, or standing at a urinal. The women were staring, but didn't seem to be upset that I seemed to be exposing myself, and most importantly, the police officers acknowledged it was not on purpose. I grabbed my penis and quickly tucked it back into my pants, apologizing while worried the cops were going to accuse me of indecent exposure.
Police have wanted to check out the bulge in front of supermarkets, and when I've been stopped for speeding, and at a drug checking point (of course).
Sometimes while mowing the lawn I've had my penis stick out of the leg of my shorts when I bend over to access the motor or grass bag, but no-one was around to see.
