I do not recall sharing my experiences with friends. But I've had two friends share experiences with me.
The first was a high school friend who years later said he had his “boys” checked thoroughly by a doctor the previous week. We were around 30 years old. He had two sons at the time, so I was a little confused. Then he clarified that he was referring to his testicles and he had concerns about a lump he had found, which turned out to be nothing.
The second was my college roommate, who was voted the “hottest guy in the dorms” at our small college. He shared with me that during his sports physical for high school football, he had a female doctor for the first time and she spent “more time down there” than she needed to. The implication was that she was attracted to him – and with good reason.
These are good memories for me because I was attracted to both guys. The high school friend was tall, thin, had blue eyes, and blond hair, and a beautiful slender penis that I got to look at back in the days when we showered after gym.
The roommate had dark complexion and a very average-sized cock and balls, which he did not hide in the dorm room but he wasn't an exhibitionist either. He was a hot jock as a whole. I watched him jerk off a few times that year and the next year in the darkness of our dorm room. There was enough light for me to see his 5.5-erect penis and how he jerked it with his right hand while playing with his balls with his left hand. I imagined his female doctor checking those balls thoroughly and him getting hard like that in front of her. One time, he brought a woman back to the room and she jerked him off while I watched and listened. He had to give her lessons on how to do it! All this happened with him on top of the covers and/or with the bed covers open. Maybe he wanted to me to watch?!
So hot. Over the years, I have imagined both of them at the doctor in my jackoff fantasies.
