JDuderrr saidI got one word for you guys--ticks. You step out of the shower and you find one suckin the blood out of your balls and you gonna scream like a gurl! I did and yeah, I did.
Ticks were a constant problem during my Army summer field training in much of the US. So it was acceptable to do "buddy checks" in the nude, usually just before showering. Just the back, from the head (which was buzzed) down to the knees, and we could do the rest for ourselves. I was always wishing for a tick on my ass, but no such luck.
But I still really had to struggle with self-control, just from a guy studying me closely like that, and me spreading my cheeks a little so he could look up there, as I did with him.
I once did get a tick on my right nut, though, in a northern US area known for Lyme disease, and so well embedded that I shouldn't mess with it. Plus I wanted it in my medical records in case I later developed symptoms, so since I was coming in from the field anyway, I went to a small troop clinic that served that part of post.
My bad luck, I go inside and figure a male will be handling my balls, but instead the only medics they had on duty were 3 enlisted females. Plus protocol required that at least 2 be present for an intimate male exam, and my being a Major probably made them extra careful to follow policy with me. So instead of a young male soldier handling my junk I got 2 females staring at me. BTW, I never got Lyme disease.
