Naturally-occuring "mismatched genitalia" in randomly-generated characters

e.g. knotted horsecock on a wolf

I know this is not a thing for everyone, but hear me out. In the preference option your can adjust a slider for animal genitalia on test subjects, as well as (un-)natural fur colors, so that idea wouldn't be far off. Maybe you could add a slider that basically manipulates the probability of that occuring (setting it to the lowest setting disables it completly) and if a subject is selected by that method it will have a random set of privates.

Of course I would understand if that is too difficult to program. Some additional input would be nice.
