I remember, at the age of fourteen, being examined at home by our family doctor. I had developed regular abdominal pain (which would, several years later result in my having to have emergency surgery for a a ruptured appendix, but that's a different story !).
The doctor, a guy in his late-thirties, examined my abdomen and proceeded to pull my shorts down slightly; at first just visually examining my genitals. He then asked my consent to physically examine "down below". I somewhat reluctantly agreed (what 14 year old lad likes having his cock and balls felt up, unless it's by a girl ?!).
He started to squeeze my balls (subsequently performing the old cough and drop test), before moving to my penis.
My being circumcised was something of a novelty for him, I think, as he spent some time closely examining the scar line on my shaft, as well as opening my pee-hole and prodding my frenulum, before returning to the scar line and pushing down (quite forcibly) my shaft skin. That really hurt and I distinctly remember gasping at the searing pain.
He really was a bastard, come to think of it; especially because he recommended that I have my frenulum removed, as according to him it was causing "tightness". Eighteen years later, my frenulum is still here and I have no complaints, but I often look back at that particular examination with a mix of sexual fascination and foreboding !
