I changed to a new primary doctor a few years back and went to see him for a routine physical. Once in the exam room I was told to undress and put on the typical exam gown which opens in the front. The doctor came in the room and after the preliminary history questions had me lay back on his exam table so he could palpate my internal organs. I don't wear any underwear and when he opened the gown my cock was just sprawled across my thigh and he did a double take. He started pushing on my abdomen but pulled up short, looked at my cock and said, "You have quite an amazing specimen. It is very distracting.", and proceeded to grab a towel from an adjacent table and covered my loins.
Quite a number of years ago I was hospitalized after a motorcycle accident. One time a nurse came into my room to change the dressing on my hip. She pulled back the sheet and again I was without underwear so my cock was draped across my thigh. Her eyes widened and as she moved my cock aside so she could access the dressing, she said, "Too bad you don't need a catheter!" As she changed the dressing she kept brushing against my cock more times than could just be accidental. I ended up getting very good nursing care while I was there.
