Many years ago now I had something similar here in the UK, but as a young teen. My medical history was complicated. Suffice it to say that I saw a very senior Consultant Paediatrician twice a year for 6 years for extremely thorough examinations / manipulationso.
He devised a very specific exercise / manipulation programme for me, which was carried out a local Clinic. Because of the nature of my (thankfully gradually improving) condition...It did involve very close scrutiny of the pelvis, pelvic girdle, lower back /spine, groin / upper & inner thighs. These sessions took place roughly every fortnight...For several years.
For many exams / sessions I was therefore naked. Because it all started at age 7, I sort of got used to it to some extent. Plus, in the late 1950s / early 1960s, the 'modesty' of young child patients was never really an issue. I must stress that all of these exams etc were very professional and nothing inappropriate ever happened. Of course, by age 12 - when I was finally discharged from these treatments etc...,I was getting a bit more self - conscious / embarrassed.
At age 13 I became a newspaper delivery boy (you were not allowed to do the job before that age). I had 3 rounds in nearby streets to where I lived. In 1965 an enormous number of people still had their newspapers and magazines delivered to their homes. Being a grammar school boy, the shopkeeper soon noticed that I was very good at book - keeping. So, he entrusted me, every Saturday morning to visit people's houses to collect monies (many people had weekly / monthly accounts back in those days).
Arriving at one particular house, a man answered the door. He told me that his wife dealt with all of these matters and he sent me through to the back kitchen. Sitting there was the woman who had been my physiotherapist for over two years. I recognised her immediately. She recognised me too, smiling as she spoke my name straight away as she made small talk whilst finding the money for the newspaper bill.
I am sure that I blushed as I made polite conversation. To be honest (crazy I know), I half expected her to tell me to take all of my clothes off and lie down on the mat in front of the kitchen fire!! I have a friend who is a GP who assures me that she would not have thought about me naked at all. But, I could not stop fantasising about it sometimes. By the time of my last visit there (aged 16).....I actively wished that she would ask me to strip..just to give me a quick session to make sure that I was still progressing medically. Oh my days!! Haha hahaha.
