I mean, you share a toilet bowl with Typhoid Larry already. The bidet isn't going to be worse than that!

And honestly, they're the best thing ever! Sometimes it drips, but that's just like getting out of the shower, except with much less water. You can wipe off the drops with toilet paper, or you can just not bother. I'll do that if I'm going straight to bed for example, or if I'm putting on running gear etc that I'm going to sweat into anyway
