I'm with your ex-gf. Maybe by everyone, your pals were including little kids. Some of us above the age of 3 or 4 have never peed in the shower (little children aside), have never considered it an option, aren't about to, and are telling the truth.
Perhaps some of the supposed shower pee-ers are stretching the truth.
