The only group physical I ever had was when I was 13 in the seventh grade. It was late fall or early winter and I was in class. Someone in the principal's office made an announcement over the PA system that all boys on the basketball teams should report to the gym immediately. I left class on the third floor of the school and walked down to the gym entrance on the ground floor. The boys were assembling in the classroom at the gym entrance. This was a somewhat oversized classsroom which probably seated about 50 students in regular classroom desk chairs with the writing surface attached on the right side of the seat. I took a seat among the other 25 or so boys from the 7th, 8th, and 9th grades making up both junior and senior varsity teams. One of the coaches was there along with another middle aged man who was dressed in slacks and a dress shirt and tie. After everyone was there, the coach made the announcement that "you are here for your physical. The doctor will tell you what to do." The doctor was standing in the front of the classroom in front of the writing board. He said "I want you all to take off your shirts in your seats and be ready. Come up two at a time and stand side by side facing me. I will listen to your heart, then turn to the side and take deep breaths and I will listen on your back, then turn back facing me and slip your pants and shorts down. When those two are finished, I want two more of you to come up and take their places."
So I took off my shirt along with all of the other boys and sat in my seat watching as the first two guys went to stand in front of the doctor. I still remember the first two boys were a smart ass short, skinny guard and a tall, stocky, stupid center. The doctor starts with the short guy and puts his stethoscope on his chest, then moves to the big guy, then the cotor says "turn to the side" and they turn ninety degrees to their right, and the doctor puts the stethoscope on the short guy and says "deep breaths" as he listens on the guy's back and then moves to the big guy and does the same thing. Then he says "turn toward me and slip your pants down." The skinny guy pulled his pants and briefs down far enough to expose half his butt and the doctor looked down at his genitals and said "ok, you can pull your pants up." He moved to the big guy, who had just dropped his pants and briefs in the front, looked at his genitals, and told him to pull his pants back up.
My heart sank as I realized that the doctor was expecting your pants and briefs to go down far enough for him to be able to see your penis and balls, not just the top of the pubic hair. I did not want to show him my shriveled up penis and tight balls, but felt it was inevitable that I would have to do this. I watched as several more pairs of guys got up and went to the doctor. About half way through the group, I decided it was time to do it. I saw this really cute guy in the eighth grade get up from his seat and head for the front to the doctor. His name was Blake and he was 14, tall and then, with a smooth chest and a young boy's face and body. I joined him and stood to his right, facing the doctor. The doctor started with me. He put his stethoscope on my chest and listened for 10 seconds before moving to Blake and doing the same thing. He said "turn to the side" and we both turned 90 degrees to our right. He put his stethoscope on Blake's chest and told him to take deep breaths, then moved to me and did the same. He was standing in front of me and said "turn toward me and slip your pants down." I turned and nervously fumbled to unbuckle, unhook, and unzip. I caught a glimpse of Blake who had already gotten his briefs down to expose a really manly, long, thick, circumcised penis with a big head on it. His penis looked like that of a much more mature man than you would have expected with the baby face. I finally managed to get my briefs down to expose my small, shriveled penis out so the doctor could inspect it. I was so humiliated being side by side with this guy who had a big one. He then said we could pull our pants back up, without doing anything other than looking at our genitalia. I pulled up my pants, rebooked and zipped up my pants,buckled my belt and returned to my seat. I put my shirt back on and went back to class, totally humiliated and hoping Blake had not looked at mine. .
