Ye have not because ye ask not.
I've discovered that there is no "list of desires" that one can compile, but rather a "list of desires I'm thinking of right now". People's fantasies are a living document. I have a few that haven't changed over the years, but I have new ones all the time that come and go. The beauty of open and comfortable communication between couples is that they can share these thoughts without worrying about being thought of as "weird" or whatever.
One fantasy I didn't discover until having been married almost ten years was going down on Mrs. WI after having climaxed inside of her. That's one we definately are glad we shared. Though we didn't discuss that one before I did it, we talked afterwards about how we each felt and discovered that we were suprisingly turned on by it. We incorporate that into our sex lives on a regular basis now.
Anal sex is a desire I've wanted to experience for a long time. I've expressed interest in, well...to put it bluntly...thrust my penis into her ass.

She's mentioned that "it looks like it feels incredible, but I can't get past the thought of it hurting". But I never, ever would've enjoyed the feeling of her using a vibrator on me while performing fellatio had it not been for expressing my interest in it.
Open and comfortable communication enables you to bring stuff up like this whenever it pops to mind! It's a great thing! Inside the bedroom and out.
