Most people with anosmia have no sense of smell. Most of them can taste basic Sweet, Sour, Bitter, Salty, and Savory. For instance, chicken tastes just like turkey, which tastes just like tender beef. Chocolate, strawberry, any flavor of ice cream taste identical. Most soda pop is indistinguishable, unless one has more "fizziness" than an other. But nothing beyond that, they usually choose their food by the sweet/sour/savory/salt y/bitter quantities and of course, usually by texture.

Nothing with a flavor goes beyond these 5 basics for anosmiatics. No food, no drink, usually nothing. However, anosmatics can usually tell "HOT" or pepperminty or alcohol, because of the sensation on their mouths. My guess is that unless it has a FEEL, like tingling or warming, she's not going to "taste" anything other than sweet, bitter, sour or salty in a lube. Their tastes work just like food and drink, unless they have a "sensation."

The flavors in lubes are food safe flavorings, so my guess is they would only taste sweet or bitter depending on the lube, no "strawberry" or "cherry" although she might be able to sense something with peppermint oil or an other "sensation" flavoring.

A good lube, though, even if it isn't flavored is always worth the money. You may want to just stick with whatever works best for your and her lubrication needs. less
