That actually happened to me once.
My wife gave me sleeping pills to make me sleepy and more importantly, keep me that way.
Later she gave me suppositories and diapered me.
I woke up (somewhat) feeling an impending involuntary expulsion. I told her about it, but added that I was very sleepy.
She genly told me with intonation that one would use with a small child, "It's all right. Just let it happen".
So, I relaxed, it did happen, and I immediately went back to sleep.
One of the best events of my whole life!
