Every day I take at least a couple of two-liter enemas, in the morning. Hot water and salt, temperature around 40c. Once, by mistake, I used much hotter water (I don't know "how much" hotter); it was very, very pleasant but I didn't repeat it for fear of doing damage. I read that many love "very" hot water, but how hot? What do you think is the maximum temperature to stay safe?
