I know, if there is any light in the room, you want to look at your bride during sex. I get it – but what if your eyes are blinding you to things you could hear and feel? If you shut your eyes, you might become aware of subtle sounds and movements your bride makes – hints about what she is feeling, how aroused she is, and what she wants. If you do less looking, you might be better able to feel and move with her.
Another possibility is that you have missed gradual changes in her sexuality over the years. By depriving yourself of your usual first line of information, you might become aware of something you have been missing.
