You can check whether you’re clean with a toilet paper, if you’re unsure. But I did so a few times at the beginning and never had stained toilet paper (so long as I didn’t stick it inside, I guess), so I don’t bother anymore.
In particular, you also feel cleaner when you regularly use a bidet (like you’re freshly showered), so that also makes it easier to feel when you aren’t clean…
Two things I don’t get about bidets: How do you know you’re clean, and how do you dry off without leaving toilet paper lint everywhere?
