We moved soon after I turned 13, so I went to a new pediatrician for my annual checkup. I had never had a genital exam, and I thought that they were only for sports physicals. Consequently, I did not object when my mother went to the exam room with me. The nurse took my vitals and instructed me to strip to my underwear as she left the room. That was standard procedure, so I was expecting my mother to see me in my tighty whities. I really didn't want my mother to see me in my underwear, but I also didn't want to be in the exam alone. What's a guy to do?
After a long wait sitting on the exam table in my underwear in front of my mother, the door opened and a woman walked in. I was uncomfortable because I thought a female nurse had come in my room by mistake, and now she was seeing me in my underwear. Then she introduced herself as the doctor. I know that this sounds silly by today's standards, but at the time I didn't know that there were female pediatricians. Oh no! Now she was going to see me in my underwear A LOT!
She and my mom started chatting away as she performed the exam. It was basically like every exam I had ever had, and I was not expecting anything to be different. Being in my underwear was a minor concern, but the main worry that I had was that she was going to say that I needed a shot or something. I was not worried at all about her seeing my in anything less than my undies.
When she finished palpitating my abdomen, she placed a hand on each hip and told me to lift up. I assumed that she was simply going to reposition me on the exam table. When I lifted, she quickly lowered my briefs almost to my knees. I had a jolt of adrenaline and immediately covered myself with my hands and pulled my knees up toward my chest. Then the doctor began coaxing me while my mother was ordering me to uncover myself. With my ears rings and my heart pounding, I reluctantly capitulated and lowered my knees and allowed the doctor to move my hands out of the way to reveal my pubescent penis and its new patch of pubes.
As I watched in a literal state of panic, the doctor very slowly and thoroughly examined my penis and rolled my balls between her fingers. My gaze swapped back and forth between the doctor and my mother, who was watching intently. I felt completely helpless. Every instinct told me to cover up, but I had no choice but to let the doctor do whatever she wanted. It was the most embarrassing thing that happened to me up to that point. Maybe the most embarrassing thing in my life.
My mother and I had a quiet ride home and never discussed the event. I did make a major point to her, though, that she wasn't going in the exam room with me again, nor was I going to a female doctor again.
As soon as we got home, I jerked off thinking of the experience. I wasn't a little boy anymore. I had pubes! And my penis was growing! And a woman literally examined my penis very thoroughly AS MY MOM WATCHED! I thought I was going to die of embarrassment.
Here's the thing, though. Despite the embarrassment, the memory of that event gave me a raging boner. I'm sure that if I had known in advance what was going to happen, I would have had a boner from the time we left the house, while we were waiting in the waiting room, and while I sat in my tightly whiles waiting for the doctor. By the time she would have lowered my underwear, it would have been ready to go. As soon as she would have touched it, I would have cum right in front of her and my mom.
I hated the exam while it was happening, but it gave me a lot of fun afterwards. I'm glad that I didn't know in advance, because I really wouldn't have wanted them to see my erection, and I certainly wouldn't have wanted to cum!
