I propose a test. Wait until your wife goes to sleep. Sneak in the room without waking her up. The move the blankets out of the way without waking her up. Then feel her up without waking her up. Report results here.
I am assuming you’re a guy here. If not, have your husband do it and see if stay asleep.
Oh good grief, we have been married for 55 years....if she woke up every time I touched her she would never get any sleep
