Douche bulbs, "proper" use?

I remember my aunt had a white douche bulb in a box in their bathroom when I was growing up in the 50's. I read the directions inside that box many times.

It explained that the bulb was to be filled with the preferred solution and the nozzle, with the shield placed in the middle, attached. The directions went on to explain that the shield was then adjusted to be used as a "plug" to keep the solution in and expand the vagina to a "gentle fullness". Then, while keeping the bulb compressed the nozzle was to be partially removed from the shield and the bulb relaxed. This would refill the bulb with douche solution. This was to be discarded and the process repeated.

My question is has anyone tried this technique for an enema? I have tried to find a douche bulb with a shield locally but they seemed to have done away with them. Lookslike I'm going to have to resort to the Internet. But, I'm still interested in knowing if anyone has tried this.

You don't need a shield on a bulb when you do an enema because the anus has a sphincter that can clench around the nozzle. In case you don't know it 😁 , the vagina has no such sphincter and cannot clench and seal around a nozzle like the anus can, which is why the douche bulb has a shield, that when pressed against the labia can help form a pseudo seal, allowing the solution to slightly expand the vagina.

Holding my lips together while douching gives me a nice ballooning feeling.........
