My wife can sit on the toilet for 45 minutes. I don't get it. I want to get on and off that thing as quickly as possible. Why do you want to hover over poo?
I'd say it's more of a revelation to me that sitting on the toilet seat itself for long periods causes hemorrhoids, than hemorrhoids being common in general.
I've been there for an hour a couple of times, I've never had it so I would never notice lol. I guess it's time to avoid it altogether.
