I agree with the other posters here.
Start out by casually exploring why she is interested.
Not an interrogation session, just some gentle questions about what she finds interesting about them.
I would then ask if she knows about equipment, bags, nozzles, bulb enemas, how to give them, etc.
Show her a bulb syringe first, and let her hold it. Tell her how it works and how gentle it is.
Don't squirt it forcefully, just gently so you don't startle her.
Is she comfortable seeing you naked or being naked around you?
If so, ask if she would like to try giving you one and you prepare the solution, soap etc.
Take it slow and you may make an enema convert! Good luck.
I'm available to talk some more.
We talked at length some time back.
