It certainly seems plausible, and if otherwise well-adjusted adults can manifest oral fixations through smoking and eating, why not through mocha-sipping as well?
In any case, Coffee Cuffs - part of the Bentwood line from Contexture Design Workshop - are where fashion meets espresso fixation. they can be worn as a cuff bracelet, and then popped off your wrist and onto a cup as an on-the-go sleeve. The added benefit: it's way more refined than the usual paper or foam sleeve offerings. Because you have to keep up appearances for the sake of those aforementioned insecurities, right?
