This is my first post in the forum. I like enemas and experimenting and a few weeks ago I did some pee enemas. Those weren't strong at all, similar to warm water. Then I thought I should try a very salty enema. Not the physiological solution, much more salty. I expected a mild result. I dissolved as much salt in warm water as I could. Then I injected 0.1 liter into my rectum. It burned immediately. It was very strong, stronger than pure glycerine. I had to push very hard. It started cleaning me out. I fucked myself with an object while there was salty water inside and the feeling was incredible and almost unbearable. Then I injected another 0.1 liter and continued similarly.
The after-effects were similar to soap and glycerine. I had irritation for days and also swelling in my rectum. I have to say that I somewhat like the after-effects also, but not always. I guess it could make anal sex very intense.
I'm no expert but I think that this very salty enema (as long as it's a small enema) is safer than soap (for the same effect) because only two materials are used and both are well-known to be used by the body. Compared to glycerine, salt water is cheaper and more accessible. I can't compare to Epsom salts because I haven't tried them.
