As a kid, the doctor would pull them down, usually to about the knee. When I got older, (and to this day) unless specifically to remove my trousers completely, I just drop them to my ankles.
However, once I had a very bad case of epididymitis. (My left testicle wanted to see what it would be like to be the size of a baseball, I guess.) First, I went to my regular doctor, and the Nurse Practitioner had me come in the office. as I limped it (Yes, it hurt THAT much) she sat with her back to me, took a short history and told me she would have to take a look. I slowly got up from the table, undid my pants and started to pull them down. When I had gotten them just below my ass, she turned around in the chair, dropped her jaw, and told me to gt dressed because she was sending me to see a urologist right away. (She didn't even cross the several feet from her desk to the table, she could see the problem from where she was.) So, I slowly got dressed.
Now, at that time, i worked in the local hospital as an ACNA (Advanced CNA). Prior to going to the floors, I was an orderly/instrument tech in the OR, so I knew most of the GU docs. She sent me to the medical office building on the hospital grounds. ( a relatively short drive from the office, but, unfortunately, I had a standard, so working the clutch was not fun.) I got to the doctor's office and he had me strip completely from the waist down. After a relatively brief (though it seemed like years then) exam, he had me dress and cross the parking lot and I was admitted for IV Antibiotics. Once I was admitted, they notified the charge nurse on my floor where I was. (Fortunately, on another floor from where i worked. Unfortunately, I still knew some of the nurses and all the CNAs personally.)
I spent a week in the hospital, for the first couple of days, i did not get out of bed. (Used a urinal when necessary. At least they didn't have to cath me. That would;d have been total humiliation.) The whole time I was in the hospital, I wore nothing but a johnny. Most of the time, I had a rubber glove filled with ice 'cupping' my scrotum.(The ice was crushed, so my sack rested in the palm, and the fingers curled up because of the position of my thighs)
Because I knew so many of my caregivers, I was usually afforded the dignity of putting the ice on myself, and they always apologized when they had to check if the swelling had gone down.
After a week of IV antibiotics, I was sent home on bed rest with more meds, and was back to work a week or so later. I know that at least my charge nurse, and the nurses on my shift knew why I was downstairs, but when I came back all that was said was, "I'm glad you're feeling better.'"
Everyone was very professional, but I sometimes wondered what the nurses might have been thinking.
Anyway, I didn't mean to stray. The point was that that only time I remember being told to remove strip completely from the waist down.
