Here's an off the wall thought. I have issues when I don't use a bidet. Paper an my butt are enemies. It leads to discomfort and frequent pooping. I think it might cause internal irritation that drives my anus into producing smaller but more frequent amounts. Normal diet and all, 1 per day is my pace. When we travel and I don't have the toilet fountain and soap cleaning me up, 3 to 4 can become a reality even when I'm watching my diet.
Hope you get it figured out.
