I didnt, but was with someone when they did. My cousin was recovering from surgery and couldn't get out of bed. We were alone together in her room when she told me she needed to pee snd asked for my help. The bed pan was already under her blacket between her legs, but not in the right possition. She asked me to push it into the right spot. As soon as I had it in a good spot, I turned to leave the room. But she asked me to stay. I couldn't see anything but definitely heard it!
