Wearing a thong to a physical exam

Men have you ever worn a thong instead of regular underwear when you went for your physical exam? And did you get a reaction from the doctor?

I was on diving teams in Junior High and High School. The required boys uniform was swimming briefs. The are designed for comfort and performance but in my day to day life I wear microfiber boxer briefs. A thong would seem too uncomfortable for me. I couldn't see the purpose for sporting a thong for a physical exam.

No nor have I considered doing so. In part, it seems a tad disrespectful, at least for me, and also don't envision wanting to feel a wedgie.
