I would like to know this as well. On the other hand I've heard bidets are great for people with hemorrhoids because the act of wiping with toilet paper can make hemorrhoids worse/last longer. 

Edit: I'm genuinely surprised at how squeamish people are regarding hemorrhoids lmao. They're so common

When I was pregnant, my OB told me that I needed to invest in a bidet for the monster hemorrhoids. I haven’t been willing to drop the money on it yet.
