I think it depends on there Bidet. i got one off amazon and I love it. It doesn’t spray everywhere. My parents got one for me for when I visit them and they got one that had a warm water hookup and that’s pretty cool too but theirs sprays everywhere, similar to what you’re describing.
I find it helps a lot. I still have to work at making sure I’m cleaned out, but once I am, the bidet takes care of the burning/itching that can be caused by the acid on the tooshie. It’s uo to you. Before the bidet I just used wipes. But that’s expensive and can clog up the toilet. This is just so practical.
