This question takes me straight back to my childhood and teenage years. From a very young age, I was drawn to that feeling, the gentle touch, the close physical attention, and especially the sweet, subtle embarrassment that always accompanied a rectal temperature check. When I felt the world around me starting to switch to quick and easy oral thermometers, I realized I had to take matters into my own hands so I wouldn't miss out on that special experience.
The first time I vividly remember was when I was 14. I was lying in bed with a high fever, and my mother came into the room with the usual oral thermometer. As she placed it in my mouth, I simply bit down hard on it until it cracked and broke. I whispered a curse and pretended to be sorry for the "accident," but it was all planned in advance. My mother sighed, went downstairs, and brought back the old, reliable rectal thermometer. The silence in the room, the subtle scent of petroleum jelly, and the slow, cool, precise touch as she checked me made my whole body soften. That feeling of slight helplessness combined with deep intimacy was exactly what I was hoping for.
Another incident happened a year later when I was very sick and my mother called a private nurse to our home. The nurse arrived with a large medical bag and pulled out a digital oral thermometer. The moment her back was turned, I gave it a sharp shake and intentionally dropped it on the floor until its digital display went completely blank. Seeing that it was broken, she smiled patiently, opened an inner compartment in her bag, and pulled out a traditional glass thermometer. She asked me to turn onto my side, and the touch of her professional hands along with the quiet, thorough examination she performed sent a wave of warmth, excitement, and anticipation through me.
Those deliberate "accidents" were my secret way of ensuring I would get that intimate, careful, and comforting examination I loved so much, time and time again.
