Get yourself a travel bidet <$20 on Amazon, and start with that. You use warm tap water from your commode.

No installation, but a bit of practice.

My proctologist ranted about general bad wiping habits in the US that damage the hemorrhoid tissue over time. Don’t spend your life in sin and misery as I have in the House of the Rising Sun, and stick to only dabbing with bathroom tissue, and use bidets to do the heavy cleaning.
