I would have absolutely no problem with my doctor, NP, or PA examining me fully nude. :) I have some background as a nude art model and even had a small role in an adult film, so I probably have even less body shame than normal.
Even so, I suspect that a lot of medical professionals probably wish NOT to view their patients fully nude- not just due to potential liability, but also their own personal comfort level. Especially when the practitioner and patient are of opposite genders.
How many male doctors have been wrongly accused of being of being creeps, molesters, and potential rapists when their only offense was doing a good job? How many male patients have been branded as perverts or exhibitionists when their body responds in a perfectly normal and natural way when being touched by an attractive female, albeit in a clinical setting?
I said it before and I'll say it again- humanity truly disgusts me sometimes.
