With any of them, listen to your body and definitely stop if there’s any cramps/sharp pains. Also nausea, don’t want to get sick. With water, don’t do it too often because you’ll flush out your gut biome. If you can use an enema bag, use salt water so the water doesn’t absorb as fast. If using a shower hose or enema bag with regular water, don’t hold longer than like 15 minutes, your body will start to absorb it and you could get sick. Air is going to be a bit more painful than water. It’s kind of like a dull ache but you get used to it with practice. Some pumps are more uncomfortable than others though, so experiment and find what you like. Don’t use an air compressor. High pressure is a big no. For larger manual pumps, like a bike pump for example, pump slowly. Honestly it’s good to pump a little slower in general with manual ones, for safety and comfortability.

What if for example i wanted to inflate myself then plug up and hold it?
With saline/saltwater, you’ll be alright for a while. Regular water, don’t hold for over 10-15 minutes. Air is fine to hold.
