My father was a professor in a hospital, he never examined me himself. On the other hand, one of his colleagues did a study about puberty and my father "proposed" me to participate. I could not refuse, not understanding very well at the beginning of what it was.
It was pretty simple, I had to go every three months to the hospital on a Wednesday afternoon. My mother accompanied me at first, and then let me go alone. There were usually other boys of the same age as I who were passing at the same time. On the first occasion, the responsible doctor had given us a little sex education course. I then quickly understood what would be examined.
When we arrived, a nurse asked us to put on our underwear. She weighed us, then measured the different parts of the body. She then lowered our panties and also measured our genitals, stretching them to simulate an erection. She noted all the results in our files.
We then had to wait, sometimes for a long time, until a hurried intern went through to check that everything had been done correctly. In turn, he dropped our panties for an examination with palpation and shift. The session ended with pictures. My father had assured me that they would not be published or only by masking our faces.
I quickly noticed that these sessions were not so disagreeable to me and I always went there without bothering, which was not always the case for the other participants. I am convinced that it is from that moment that I am attracted by medical practices.
