I just wanted to share a recent experience. First some background. Years ago using urinals could set off a panic attack in me. Cubicles were ok most of the time but not always. I increasingly used alcohol to deal with the problem in social situations and just limited fluid intake in situations where I could not drink alcohol.
I trained in counselling and CBT and was able to largely overcome my paruresis. Urinals are no longer a problem even if there is 20 people in the toilet with people stood either side of me.
I made a video series of the process I used which is shared on the UK paruresis site and on you tube.
In the last 10 years bladder lock has been very rare for me and in the last 2 years I had zero occurances and zero avoidance.
But a few weeks ago I experienced bladder lock at a sports stadium despite it being somewhere I visit weekly with no problem. I had been a bit anxious about something unrelated and background anxiety can play a part. The following week the same happened again. Years ago this would have really affected me and I would have returned to avoidance, safety behaviours or alcohol. But I know that is a slippery slope. So the following week instead of drinking less water like I used to, I drank more to make sure I would need to use the toilet.
When the need was sufficiently strong (but not uncomfortable) I visited the toilet. Success. No bladder lock. Although it wasn't quite as busy as the previous time there were around 10 people in there. I will continue to use this toilet when busy and I know that within a few weeks I will be back on track and will probably go another year or two before it happens again.
You see paruresis is a lifetime condition but if you persevere and don't give in to avoidance and safety behaviours it can become a very small and unimportant part of your life.
For those in the earlier stages of recovery I hope this will help motivate you to keep working on it and help you deal with setbacks.

Nice write up, sir!
If you thought of the first incident you mentioned as a setback then think of your recent success at the toilet as a setforward to a mental & physical positive future.
