I'm Italian and I must support @FaceDeer 's point, these are standard in my country (and they should be standard everywhere, damn barbarians) and they are definitely better than a spray nozzle attached to a toilet. You can also use them for other things, like washing your feet.
You use toilet paper first, then move to the bidet. Which, btw, is next to the toilet, so even if you didn't clean yourself with TP it's pretty painless to move over.
I think there's confusion about which versions of bidet we're talking about. The kind I'm lauding, the ones like a little shower head, are attached to the toilet you're on. You don't need to go anywhere to use them, just reach over and take it from its holder.
All I can say is that if you've never tried a bidet before you'll likely be very surprised by how little sensitivity you've got to cold water down there. It's simply not uncomfortable or even particularly noticeable, either in my experience or in anyone I've talked to about it (which is admittedly not many - it's not a common topic of conversation).
The hand bidet was super cheap and the shipping was free, so I figured "why not give it a whirl?" And it worked out great.
ill second that, i thought it would be a problem but decided to just endure the cold because i didnt feel like running power over to the toilet but turned out not to be a problem at all. if anything its sort of refreshing lol
Nope. Not sure what else to say about that, it just isn't. I guess individual tastes may vary though. If it's the temperature you're concerned about I think you'd be surprised by how little temperature sense people have down there.
