I think the best choice is to use a plug to be plugged , and a nozzle to take a enema .
I tryed the enema butplug black , it leaked , the central hose was quickly loosen ,
the position in depth of the hose in that type of butt plug is very important ???
Too far in the plug the hose will be obtured by the inflation , so no flow going thru :(
Too far out the plug it hurts the anus when sliding in :(
Whith a light inflation the hose move in or out the plug :(
Then I used it as plug , with some lube , evidence , and it popped out when inflating :(
I was 3-) 3-) 3-) because the budget price of the toy , the transport and the TAXES my wife had to pay !
Now when playing with a inflatable plug we are using this one
YES it popped out after inflation , but(t) so efficient to prepare me for more hot pleasures .
Remember a inflatable plug will pop out more easily than a rigid one , because when it is pleasurisable you clench all your pelvis muscles ,
like when you have ( or try to have ) a bowel movement .
For the large plug I enjoy to use , I have added a piece of hard plastic pipe (like for water bathtub exhaust)
diameter is 1"1/2 and lenght is 3" ( diam = 40 mm and lenght = 70 mm )
on one side I used a drill to make a half round hole .
When sitting on the plug I never can slide it completely inside me ,
using this sur elevation pipe it push the plug more betwween my buttocks and slide completely in ,
the inflation bulb is slided into the pipe , it enter where the end is flat , and comes out wher there is a half round hole
so the inflation hose stay free and not clamped :-[ so GOOOOOOOOOOD :-[
