When you narrow the criteria of who you want to respond, you get less response. You want someone from Melbourne, with a shy bladder, who wants to discuss it, on LPSG.
Not sure why you care about location unless the shy bladder is a fetish you want to play out with someone. But if that is the case you may need to be more direct.
I'm not from Melbourne, but I had that problem for many years. It ran hand in hand with social anxiety. I found as I worked on things to reduce my overall anxiety my shy bladder problems abated. For many years my trick when needing to take a piss next to someone at a urinal was to force myself to think really hard about something else. Being a geek at heart, my trick was by reciting sequential prime numbers to myself, as I approached triple digits and it gets harder I'd be able to piss. Hope that helps. best of luck
