Moliere makes a good point, and yes people can injure themselves, point is, most of us are doing safe and sane enemas, and to listen to the medical profession we should all be unable to have a BM without an enema and other issues. In my humble opinion that's not true for most people.
I have taken thousands of enemas in my 72 years with no adverse effects, and I am sure there are many others that say the same thing.
Or, simply stated for 65 years I have taken or been given at least 3 enemas a week, that's 10,140 enemas, now during the years between age 22 and 55 most times it was double that amount, frequently more, so that brings the total to 15,288. Now let's put in a fudge factor and say I only achieved that amount 60% of the time, so conservatively that's still 9,172 enemas.
So thinking it over, yes, I have had or been given over 10,000 enemas! I'll bet that's not even close to the record of some here.
Interesting to note, I had one female friend who really got hooked on enemas at the age of 24 following a Barium Enema that gave her the most powerful orgasm she ever had, and to quote her, "Right there in front of god and everybody." She said after that her enemas were at least 5 a week and often more, and I talked with her about this when she was about 35. When I visited her at her home near Carbondale, Pennsylvania she had a collection of toys that would rival anyone here, so let's do the math...
11 years is 572 weeks times 5 enemas per week totals 2,860, and her comment was that is was frequently more than 5, because some days she just kept getting herself off. Again throw in a fudge factor and I'd say a minimum on 1000 enemas a decade or anywhere from 6,000 to 18,000 enemas in her Lifetime!
Anyway, as far as I know she is still alive and well, and close to my age, so her number may exceed mine.
Crazy numbers, but with some of us being frequent masturbators, both male and female, I think 10,000 enemas in a lifetime has been achieved!
