What I use far more often than anything else is a Klystra brand "Paris" red 3-qt HWM style bag with a long smooth black hose.
I have a couple of nozzles I use. I have a 3-inch long flared nozzle that makes a good retention nozzle. Only ONE time it ever came out. That was when I was in knee-chest retaining the 3rd enema of a session and the bisacodyl kicked in!
Fortunately I didn't leak, but it WAS a close call.
I have a 5-inch long beige flexible nozzle with a triangular tip, that I have been using a lot lately.
Only once that I had a problem with it. One time it detached from the bag and my bowel pulled it right in!!
Once I calmed down and was about to get dressed and head for the ER, the bisacodyl kicked in and any solids left in my lower bowel including the nozzle blew right out Had to put on a rubber glove to retrieve it.
I also own a 4-qt open-top "great white" open top syringe.
That one has a wider ribbed brown hose. I have a 5-inch rigid "Barium" style nozzle for use with that bag.
I don't use it a lot, but when I do, it is always a moderately painful experience that results in some degree of nausea.
I still have a couple of my Mom's old 2-US-QT Faultless brand bags At least one her Mom bought for her right after they moved down from Canada
I KNOW my Grandmother was pressuring my Mom to douche more often than she wanted to, so it may have been for that purpose,l and the other, which is from the same era, could have been from my Dad. On both of those I have straight 3-inch enema nozzle and a vaginal nozzle, but I have never used either for a douche. One of them I tried using for an enema a couple of times and the holes got clogged with poop both times, that was when I bought that 5-inch nozzle
I have a smaller open-top thinner plastic bag from the 1990s I hardly use it
I DO keep a blue bulb around in case i need to add water to a Fleet enema.
