When I was 14, I had to go to my pediatrician for a physical to enroll in High School. Naturally, being a 14 year old boy, I dreaded having to be examined by a female doctor. I sat on the exam table in just my boxers, while she did the usual.. throat, eye, ear... stethoscope etc. That summer I had experienced a not uncommon thing in teen boys, a condition called gynecomastia, which causes male nipples to temporary 'bud'. (Didn't have a clue at the time what it was, but was sufficiently embarrassed about it that I hadn't taken my shirt off all summer).
The Dr was very kind in explaining precisely what was going on with my nipples, and that in most cases they will return to normal in a short period of time. She touched them to make sure that the 'lumps' were normal, and they were so sensitive, that within seconds I sprung a boner, and my dick jutted out of the slit in my boxers. I was incredibly embarrassed, and fumbled to get him covered up, and the doctor said 'hold on a sec'. She told me she wasn't concerned that I had an erection, that it happens all the time and was 'normal'. She said she was concerned that there may be a problem with my foreskin. She put on latex gloves, and asked me to lower my boxers. She then proceeded to pull my foreskin back, and asked me if I felt any discomfort.
All I felt was unadulterated pleasure! She continued to manipulate my foreskin, and within seconds I had an orgasm, spraying my cum into a puddle on the floor. Now I was ready to crawl under a rock. She again told me not to worry, but that it appeared I had a condition phimosis, and that she would need to talk to my parents. I must have gone pale, because she quickly added... oh just the phimosis problem. Not that.. and looked over at the puddle on the floor. And she added and I won't ask you to show your mom either ok?
God I loved that doctor! She handed me tissues to clean up myself and the floor, then I got dressed and we 'talked' with Mom. Only bad part was having to get 'clipped' six months later.
But I still smile when I think of that day all those years ago, and what the doctor must have really thought!
