A beautifully written article about something that is a normal thing on our side of the world... It's not unusual at all and we have been using it at all time. It's also a norm to use your hands and wash them afterwards, which may sound surprising to many.
Either way, we definitely would go for a bumgun or an internal spray that is usually installed inside the toilet under the seat and is a triangular plate that sits on the toilet with a spray tube that shoots out water which too is very useful as you do not even need to set the position of the bumgun LOL!!! ;) ... Cheers!
