It just goes to show doesn’t it that everybody is different.
Back in March of this year I was in India doing a tour of the state of Rajastan which is essentially arid desert with a lot of wild shrubs and bushes. No real pit stops or amenities when travelling and me and the wife were travelling with 3 other couples.
Women being women needed to go for a pee but being miles away from the nearest rest stop it was suggested that they go in the bushes and the look of shock, horrror and then indignation we got was just scary! Needless to say they held it but the resulting silence from them while it lasted was fantastic
