@PeachySummer @sun About your 1., stand by for TMI: I have to hold my dick when I sit.

American toilets generally are so small that either my log smears the seat or my penis is jammed into the bowl's side. So when I sit on an American toilet, I have to deflect it inwards, into the bowl. Fortunately, in most case the water level is not high enough to create a problem.

I've been to places that have sufficiently elongated toilet seats, but they are very uncommon. I only ever saw those in public restrooms in offices. All of my houses had small bowls.
