Not always effective in a nightclub. I've had the door opened a few times by a bouncer assuming I'm doing drugs in there. They see you queuing for the stall for the 6th time that night they tend to get suspicious! Fair enough though because sometimes I was.
I suffered with this most of my life. Anxiety was the cause for me. My anxiety was diagnosed only recently for unrelated reasons but the treatment has had the fortunate side effect of fixing my shy bladder!
You can't pee if you aren't relaxed.
You can't relax with debilitating anxiety.
I have been to the urinal a couple of time and had no pee and been the dickholder. Now I wait until I'm filled with pee and confidence and let it flow with a gracious splashing stream.
There do come times when a fellow can't pee. I don't look, I just carry on and remember how far I've come.
