Haha - bad idea. What if she wakes up when you mess with her hand? She will be half awake in the middle of the night, lights off and you sitting on her side. Then you will have to wing it?
That said, nothing wrong with doing it in private. You would not get me to kneel around in an restaurant either but i.e. on your favorite hike, when you get to the top of the mountain etc.
I am amazed how quickly you guys jump back in after a divorce. If I ever get a divorce, I will have to be unconscious too, to be engaged!
