Not too often, but I hear you.
Therapists tend to describe me as "fascinating".... One even asked if she could video tape my sessions to show her supervisor.
I'm still not at all sure if I should feel flattered or offended, and that was a few years ago.
Doctors... One or two have given me the "interesting specimen" treatment, their personal curiosity was painfully obvious, but it didn't rub me up the wrong way or anything, I just brushed it off.
