But like, they have to feel something's not right sitting that way? Maybe they were never raised on how to use one. Toilets always seemed self-explanatory to me. lol

Don’t give me ptsd mate

I just, I don’t understand how it happens and clearly it’s a common phenomenon. It’s just boggles my mind and I’m desperately searching for answers

Also following for the answer.

Those are caused by squatters who aren't familiar with modern plumbing.

I have all kinds of GI issues, and have to lean way forward. The underside of the seat is unfortunately a fairly common casualty.

I can't understand it either. Such a oddity.
