@Reminiscence, I've used a bedpan a few times in my life and it's not as bad as it sounds. I was able to sit up in bed, so I could assume an almost natural position. It was a little embarrassing having someone else clean me up after I was done, but at least I wasn't uncomfortable.
I'd say if you are a man and you have a problem with urinating into a bedpan, ask the nurse for a plastic urine collector. I felt more comfortable using one of those, anyway.
