How do you and partner (real or fantasy) initiate an enema?

Whether this is what you actually do or what you would like to happen, how is an enema for you initiated? Does your partner tell you that you are going to get an enema? What does he/she say? How does that make you feel? How does it proceed from there? Do you have to ask for an enema? How do you do that? How does asking for it make you feel? How do things proceed from there? How could it be done differently that would add to your enjoyment or heighten your arousal?

Of course, after I think about it a bit, I will answer my own questions.

All I have to do is ask my wife and she's always obliged. I may just say "would you help me with an enema", or "I think I need an enema". We prefer to use her language (Thai) for the enema itself. They say "soo-an tong" (wash or flush stomach). But after nearly 45 years of marriage, most of our smalltalk is a combination of English and Thai anyway.. It makes it easier to gossip "somewhat privately" about others around us, say in the mall or anywhere. But sadly, no amount of asking (or pleading) in any language has cracked the code of allowing me to give her enemas.
