About 25 (maybe 30) years ago I had a family member who required hemorrhoid surgery because they used to read novels on the toilet. It was a long and painful road for them. Do not recommend.
When I was a kid, my dad had some Kurt Vonnegut book (I think Breakfast of Champions) in the bathroom. I sat on the toilet for a couple of hours while I read the entire book. And that is how I got introduced to Kurt Vonnegut.
If one were to sit on a toilet and read a book in its entirety, that would certainly be the book to read. Vonnegut includes a crude drawing of an asshole in it.

This guy Vonneguts
In my family, we read novels on the toilet. It’s worked out well for 60 years or so with nary a hemorrhoid. Maybe lucky genetics or something.
Eh had em. Still worth it. That's what banding is for.
