I support your erect wiping research, and I hope you keep us posted. There's nothing worse than an electro toilet thinking your down and getting your ass all wet with a mixture of water and poo. On that we can all agree.
Also, someone recently suggested to me that men are perceived as sit down wipers and ladies as stand up wipers. I don't have the data on this. Myself, I sit down about 80-90% of the time, thought I'd never exclusively stand up, it's like a finishing maneuver.
I hope this helps and would love to hear all thoughts on the subject!
