When I was eighteen, back in the 70s, I went to live with my aunt and her three daughters (Sarah aged 22, Rachel, 24, and Rebecca, 25). My aunt was very uptight about anything sexual, very prudish. She was also a nurse and worked at a small clinic. The town was very small and had only one doctor: Dr. Moss, a woman in her mid-50s and definitely not much to look at. I was very shy then and always avoided going to that doctor for anything.
One day, I was playing baseball and I got hit in the groin by the ball and I was in a lot of pain. One of the guys took me home and I started towards my room so I could lie down and try to get over it. Sarah noticed I was hurt and went to get her mom.
My aunt asked what the problem was and when I told her, she insisted that I see the doctor. I protested a little, but I was in such pain that I didn't put up too much of a fight. When we got there and I was signed in, I told my aunt that I didn't want her in the room when I was examined. She objected to this, but I insisted that she stay out because it would be too embarrassing. She agreed.
Once the preliminary vitals checks were done and I was in the examining room, the nurse told me Doctor Moss would be in shortly. When she came in, she said "Hi" and asked me to describe what happened. I told her I got hit by a baseball and I was in a lot of pain. Dr. Moss said that based on my pain level she didn't think I had a twisted testicle. She told me to take off everything except my T-shirt and socks and to put on a gown and that she would be back in a moment.
