Well, everything comes out when I exit through the leg (of tighty-whiteys or jock strap). It comes out of the underwear, but only the dick comes out of the trousers... and not very far either, being a 'grower'.
Lately though, after unzipping, I've been hefting my balls over the waistband of the briefs. It helps take the tension off when I... ...re-apply the ring over the restoring foreskin.
But in public restrooms? I'd like to say that I pull out my seven-soft-inches for all to see, while standing 2 feet back from the urinal. I'd like to say that. But the truth is, again, that I'm a grower. And the truth is that I'm still rather pee-shy and seldom piss in a place where other guys are likely to come in... unless it's a gay bar pisser, or a sex club; some place I know it's OK to stare and cruise while I wait and wait for the piss to come out. I can seldom start to piss if the other guys are already in mid-stream. Only if I have to go real bad. I'll work on that.
