My urologist asked me if I would be interested in having a spermatic cord block to relieve the pain from my cysts. Anything to relieve the pain, so I agreed. The block consists of an injection of a steroid and anesthetic into the spermatic cord. That happened this afternoon. My dr referred me to his colleague, who did most of the injections. I didn't know who he was, so I prepared for anything. So, this morning, I got in the shower and shaved my balls, and groin, so I would there would be no evidence of hair and give them an unencumbered path to the injection site. When I arrived at the office, the nurse took my vitals and told me that the resident would be right in. In a couple of minutes, he arrived. He was tall and skinny with black glasses, a pleasant person. He explained that he was working with the urologist and learning the procedure from him. He went over the whole procedure and then told me to undress completely from the waist down, sit on the exam table, and cover my lower half with a sheet. He left and I did what he tole me to do, A couple minutes later, he and the dr came into the room. He was a middle-aged Asian-American man who asked me some questions about my problem. He then proceeded to listen to be heart, etc, then told me to lie down. While he was preparing the injection, the resident was working to properly drape me. I told him I wasn't shy , so he didn't need to drape. He okayed it and removed my sheet, exposing me to both of them. Before the injection, they both felt my testicle and the dr held my penis and asked if there was any referred pain. I told him there wasn't, so they proceeded. The resident took my testicle in his hand hard enough to stretch the skin. The dr felt around, located the cord and did the injection. Now, I had been lying there for a while with two men feeling me up, so, despite the injection ( which didn't hurt) I got a little turned on. The resident wiped some alcohol on my testicle. As he was doing it, my penis, with a mind of its own, throbbed and erected, hitting his arm. I was pretty embarrassed, but he didn't indicated that anything had happened. The dr, left and the resident was completing the computer instructions for aftercare. I quickly rushed from the table, fully hard, and grabbed my underpants from the chair and got them on lest he see it. He said his goodbyes and left the room. I was left standing in my briefs with the front tented. As I left, I had to smile and let out a small laugh.
