As an adult, I do all my genital exams myself. I find no good reason to pay for something i cannot do better myself.
As a child, preteen and early teen, my father examined my genitals regularly. He pulled back my foreskin, looked at my glans and checked inside my urethral cleft. he also felt at my scrotum, and at my lower stomach. he also injected some medicine into my urethra with as syringe. He also separated my legs and stuck a finger inside my anus and checked my prostate. Usually they had given me some sedative medicine, so that I was very sleepy, so I remember these different things from different occations. I had the impression that he had learned the procedure from some health authorities at my school. Eberything done by me on my back.
When i was 12 had had a very lengthy exam in a special area at school under heavy sedation. They surely did much more than just a geenital exam. But what I remember is that they used an instrument inserted through my urethra, an anal speculum and something that must have been a sigmoidoscope. I woke up briefly and got aware of these particularities. I lay straight when they inserted the instrument through my penis, but later on I had my legs in stirrups, lifted, spread and widely flexed., but not quite in the same way as women by gynecological exams.
At my yearly physicals, also in school, I was naked, but they did not do any specific genital exam, exept a brief testicular check at 7 and an hernia check at 14, both standing. During the scoliosi check, however I had to bend foreward as much as I could, and the nurse or doctor looked at me from behind. I was somewhat stiff and I thought that they checked my flexibility apart from looking at my lower back to see any misalignment,but now I think that they also looked at my anal area and the area between my legs, and could see how my prostate and shielded genital parts between my legs were developing.
The hernia check at 14 got done by the doctor insering a finger up inside my chanals at both side of the scrotum while having me tense my abdominal muscles. I got surprized that this was possible, and it gave an astounishingly excited feeling. My skin at that area got wrapped somewhat into the channels which stretched the scrotal skin and the inguinal skin, which surely contributed to the feeling, but it did not hurt. Another boy thought that it hurt though.
3 boys out of 20 got diagnosed with hernia by this check and had subsequent surgery.
