For some it seems quick, for others like me it was 10 to 20 minutes? I thought originally my mother put me naked on the toilet JUST to see if I would have a BM, and save her the trouble, but later realized her mind was made up, when having a BM didn't change my fate. I realized she always made my first enema while I was in the bathroom and I had to watch, and she was using really hot water to dissolve the ivory bar soap until the water was pure white, by running the soap over and over in her hand, and splashing it in the sink. She was also letting it cool, to the temperature she wanted. She always gave and took herself, very hard to hold, crampy, very soapy enemas followed by a clear flush, and always ivory bar soap. Thoughts?
