I always leave my belt fastened but unbutton and unzip. I pull my cock and balls out over the waistband of my underwear. As I have gotten older, I have to press under my balls to totally drain.
I love finding the bathrooms that still dont have the side shields. Its getting harder to find them. One grocery store still has two urinals side by side so I always have hope I will see something good beside me. I also like finding them on the interstate when traveling. Notice when the guy beside you finishes whether he turns away from you or toward you. I have let many see all when they turn toward me.
There is still a great erotic rush when I know the guy beside me is looking. I try not to disappoint yet stay neutral in case hes a cop.
I mentioned this in the other post here who has peed in a open trough no barriers and one long urinal no shyness allowed
I certainly have many times - about 20% of the urinals in the UK are that style, as were the ones on the Thames where I dropped my shorts to my ankles to urinate as they had no fly opening.
I just unzip and tuck my briefs under my balls and go. Unless if I'm wearing button fly jeans then I have to unbuckle, and open up my jeans, tuck briefs under my balls. I was once at a urinal in a southern county courthouse where there was a step. It was kinda cool stepping up to the urinal. I've also used troughs.
I wear pants held up by suspenders and a little larger than my size. When I wear jeans I go commando and I simply unbutton and unzip and open wide - suspenders hold up the pants and float on me comfortably. I've never seen in real life any man bear his entire ass when taking a piss as found in many staged photos. How I wish it would happen.
