Same here but I've taught myself to relax completely and I now sit down to pee.
I make sure I completely empty my bladder just before bed time so I don't need to go during the night.
- I ride a bicycle a lot so I'm generally fit but "time waits for no man".
Note I've always used "Brooks" style leather saddles so I don't suffer penile numbness.
When I was about 14 I went to a Kiss concert and I was in the crowd crush near the front of the stage. I wasn't able to get to a toilet so I just held it for about 6 or 7 hours. When the concert was over we were walking back to the car and I just had to go... I found a tree and proceeded to "equestrian pee" for about 10 minutes straight!
