LADIES: Have you ever had a Wartenberg wheel run along your soles?

Have any of you ladies ever had a Wartenberg wheel run along your soles? Play exams or real. It's one of my favorite tool and the reactions always vary. Some don't mind, some giggle, some flinch and hate it. It's an odd sensation for sure. It's a perfect instrument for a play doc who loves feet. Curious if there's been an experiences here.
