I am a 72 years old French retired lawyer and I enjoyed a lot your post about your rectal temperature routine.
I have had a strong rectal temperature fetish thoughout my life and most of my girlfriends have shared this strange addiction.
In my late twenties, I had a long standing relation with a smart language student who was very much into medfet. She had set the rule that, every time we were to have sex, she would impose on me a comprehensive medical exam. This mock exam allways ended with her taking my rectal temperature on her lap. I was in Heaven.
More recently, for several years, I had a strong relation with a ladyfriend who was as much into rectal temperature as s myself. When the Covid erupted, she insisted on moving with me in my place, pretending to take care of me, at risk with the virus, due to my age. She then decided that we would take eachover's rectal temperature on our lap, every day, first thing in the morning. This morning routine, keeping the thermometer inserted for 10 to 15 minutes, often turned into sex preliminaries.
My girlfriend dumped me 3 years ago and since then I have been alone to take my temperature. It is less fun than having someone do it for you. I take my rectal temperature about once a week. Keeping the thermometer inserted 10 to 15 minutes, I close my eyes and try to remember the good memories of my various rectal temperature sessions.
As a matter of facts, I have come to consider rectal temperature taking as a way of making love, and a very intimate one. Of course, it has to be recioprocal, you take my temperature, I take yours.
