Girls, have you ever peed in a urinal?

Were there any guys there or were you alone / with female friends, and why did you do it?
If you were desperate would you use a urinal even if there were guys there?
What are the practical challenges?
Guys, how do you feel about this? In the UK many urinals don't have privacy screens, so I might feel a little self concious, but I'd be fine if there were a privacy screen - in fact it would be kinda fun!

And no, I don't have a pee fetish :-)
