For the last few years we had a simple bidet attachment on our master bath toilet. Just a water spray, not heated, but it's a gamechanger.
There are portable ones, like squeeze bottles, or toppers that fit on a plastic soda bottle. My silicone squeeze bottle bidet lasted 2 years.
The silicone ring seals of press-fit toppers dislodge too easily.
I prefer screw-cap tops. "Igneous" makes a good one. You can DIY one from a regular cap with a hot nail and pliers: use pliers to hold the nail over a candle, then pierce the cap top at an angle.
