After experiencing the discomfort and embarrassment of a colonoscopy in Philadelphia, I decided to have my next one carried out while visiting friends in San Francisco, where the beautiful nurses are allegedly much more gentle and accommodating.
As I lay naked on my side on the table, the nurse began my procedure.
"Don't worry, at this stage of the procedure it's quite normal to get an erection," the nurse told me.
"I haven't got an erection," I replied.
"No, but I have," replied the nurse.
