The morning rush is over. I have just finished my third patient of the day; a young man with a very tight urethra. He was quite shy, which is always a challenge. It takes patience to coax the prostate into releasing its fluid. I had to use my fingers deep inside his ass to get the job done. My hand is still cramping. It is a good kind of tired, though. Knowing I helped create a sample for the bank is satisfying. Now, I must clean the stirrups and prepare for the afternoon appointments. I hope the next one is less timid. I prefer a man who knows how to thrust.
