David, an IT consultant from the English Midlands, has paruresis or shy bladder syndrome.
Ever been standing at a public urinal and found you couldn't go? You're not the only one. It even has a name - Paruresis.
If you're not peeing out the end of your penis you may have undiagnosed hypospadias. It can be treated.
