I am too, though a surprisingly large number of my patients don’t want a witness, and in the place I work, we do often lack staff to act as such. I do get verbal consent prior to this sort of exam with every patient, making sure they know they can refuse it, even though I recommend the exam.
I had male patient with genital complaints who actually refused to be examined by any male, insisting he must be examined by females only. He was told that was NOT an option. He was offered a witness (gender not specified) but refused that. He left my office and approached my lab tech, demanding she examine his genitals. He did get written up for that.
