After experiencing the discomfort and embarrassment of a prostate test at a military hospital, I decided to have my next test carried out while visiting in San Francisco where the beautiful nurses are more gentle and accommodating.. As I laid naked on my side on the table, the nurse began the examination. "Don't worry, at this stage of the procedure it's quite normal to get an erection," said the nurse. "I haven't got an erection," I said. "No, but I have." replied the nurse. Moral: Don't have this procedure done in San Francisco!
