A cold feeling?

I remember the nurse massaging my butt with vaseline then slipping the thermometer which passed easily my oriphice (against my will) giving a cold feeling very invasive and humiliating. It was not the only instrument gave me those feelings at that time. I remember also the stethoscope pad touching my nipples and also steel instruments the doctor used for preputial dilatation.

My mom was a nurse and had a long, glass rectal thermometer she would use on me if I was constipated. She would use Vaseline on it after wiping it with alcohol and it definitely felt cold entering my rectum. Her method was to insert until she felt resistance, which could vary depending on if there was impaction.

There is a big difference between that feeling and either a metal temp probe with a plastic cover or a digital plastic thermometer. Neither are the same as the cold glass feeling sliding in while hearing "and here comes the thermometer". It's never as cold and never as deep.
