After experiencing the discomfort and embarrassment of a prostate test on the National Health Service, a friend of mine decided to have his next test carried out while visiting in Thailand where the beautiful nurses are rather more gentle and accommodating. As usual he was asked to strip off, he lay naked on his side on the bed and the nurse began the examination. At this stage of the procedure it's quite normal to get an erection" said the nurse. I haven't got an erection" said the man. "No, but I have" replied the nurse.
