Which half did your doctor prefer? (You don't say if it is a male or female doctor).
To tell the truth I have had a female doctor do a DRE on me - it was on my release medical from the military - the only time in my life that had ever happened.
I remember my female doc doing it, but now I'm wondering if the male doc did too. I don't have a family history of anything that would make them do that, I just always thought it was part of the exam, since they're in the general vicinity anyway.
