I can still vividly remember my medicals during my time spent in the senior (upper) school. This was England late 1960's early 70's and schools were much stricter and corporal punishment with slipper or cane a daily occurrence.
We had 2 medicals in Upper school one in the 1st year at the age of about 12 and the other in 3rd year at the age of about 14. We also had to see the "nit nurse" every 12 months and have a dental check every 12 months.
For the medicals one of your parents were supposed to be there and letters were sent to home to ensure this happened, normally the mother attended as father would be at work.
For my 1st medical, on the appropriate day, my name was called out with three others to go to the surgery where we were met by our mothers. When called inside we were asked to remove our blazers and shoes and waited on some chairs. When my name was called out I made my way (with mum) to the nurse who weighed and measured height, waist and chest and asked a series of health related questions (which mum normally answered) and that was it, 10 mins.
For the second medical at age of 14, the same happened, a letter to home, name called out in class with 3 others to meet our mothers outside nurses surgery.
When we were called inside a lad from the previous 4 was sat waiting with his mum wearing just his white Y front briefs and socks. We were our asked to remove our clothes except our underpants and socks. I didn't mind this too much because we were used to seeing each other in our underwear getting changed for gym and the showers and mum had seen me in my vest and pants plenty of times. At this period of time (late 60's/early 70's) most lads wore white briefs, normally Y fronts, there were no boxers and very few coloured or patterned pants. My mother always bought my underwear from Marks & Spencer and I wore white Y front cellular briefs. they were like a aertex type, a very fine mesh, fairly common and still sold today. We gave our mums our clothes to hold for safekeeping and waited our turn.
One lad returned from seeing the doctor, with his mum,to get his clothes which were left on a chair, he looked a bit red in the face and fidgeted down the front of his briefs for a moment, rearranging himself. The lad before us went up to see nurse and we could see him stood in his his socks and briefs, mum sat next to him while he was weighed and measured. They then went round a corner to see the doctor as someone else returned to where we were to get their clothes. I thought that he looked slightly aroused because the "pouch" in his Y fronts stuck out slightly.
When my turn came we left my clothes on the chair and went to the nurse, mum sat next to me as I was weighed, measured. I heard a slight cough come from where the doctor was and could see round the corner at the doctor. The lad before me was stood in front of the doctor with his white Y fronts down by his knees and his mum sat next to him as he had the "cough and drop". I went red with thought of having this done especially with mum sat next to me. It had been a few years since either of my parents had seen me naked.
After nurse had finished we went over to see the doctor. i stood in front of him while mum sat next to me. He asked various health related question (which mum again normally answered), then listened to my heart. He then asked me to walk away a few yards turn round and walk back, to check posture.
After this the Doctor put his hands over the waistband of my Y fronts and lowered them to my knees. I was blushing furiously and just stared straight in front, concentrating on the wall. The doctor took my testicles in his hand, felt them, gently squeezed them and asked me to cough. I couldn't help it but felt myself getting slightly aroused. I looked down and could see my cock was more or less pointing outwards, not quite horizontal. The doctor took my cock in his hand and eased back my foreskin back over the nob at the end of my cock as far as it would go. I had never even done this myself, not when going the toilet or when I masturbated. I winced a bit as he did this and as the end of my cock was exposed and felt really sensitive and I developed a full erection. I glanced down and the doctor was inspecting the end of my cock and pulled it down slightly with one finger to gain a better look (probably because it was erect).
The doctor then said to mum "Your son has not got any pubic hair yet I see". Of course I knew this to be true but never thought much of it, when we in the showers I had noticed some lads had a good bush, others just if a few hairs and a few, like me, without any yet. Mum just said to him "Yes - O.K." I don't know wether she looked or not because I was just staring intently at wall. I guess she could not really miss, beng sat right next to me. The Doc then said "Well every thing else seems to be working o.k. I guess he is just a bit late developing pubic hair, it will happen soon no doubt. He then told me I could pull my underpants back up. I thought "great".
Unfortuantely, having an erection made my Y fronts a tighter fit and being the cellular type (fine mesh) my cock showed up quite clearly stuck up the side of my briefs and nearly poking over the waistband. My foreskin was still pulled back and the nob on the end was really noticeable. I had to stand there while the doctor went through a few things with mum and the end of my cock was really sensitive against the material of my briefs, my erection would not go down and I just stared intently ahead, I had to contcentrate to stop myself from ejaculating, which I don't think I would have ever lived down.
When we had finished we had to walk back to where my clothes were and there was the next lot of lads sat there in their white briefs waiting their turn with their mums. I could see them look at me, and yes I still had an erection showing through my Y fronts. As I tucked my vest in to my Y fronts I discreetly eased my foreskin back over my nob amd got dressed.
I quickly said "bye" to mum and returned class, by which time my erection had gone down. I thought I would really get my leg pulled at break time but my class mates weren't too bad, I suppose they thought it could have happened to them, and I learned I was not the only one to get an erection during the medical. When I got home I could not face mum and just went straight up to my room. When dad came home I heard them talking and he came upstairs. He knocked on my door and said "you o.k." I just said "Yeah, fine". He told me he'd heard what happened but not to worry as these things do happen to lads my age. He said that mum understood and would be o.k. and to come downstairs. This made me feel a bit better. but I still felt a bit sheepish and it took a day or two to get back to normal.
Sorry to be so long winded, but this is a true story, any similar happen to anyone, I am sure most medicals in England were similar at that time.
