At 72, I have had a strong rectal temperature fetish thoughout my whole life and I have been fortunate enough to have several girlfriends who shared my strange taste And I would say I have come to consider rectal temperature taking as a way of making love, just like oral or anal sex.
In my late twenties, for several years, my girlfriend Maria was very much into medfet and she had set the rule that, every time we were to have sex, she would impose on me a compréhensive physical ,which concentrated on my penis and testicles and allways ended with my rectal temperature being taken on her lap. I was in Heaven as she played with the well inserted thermometer as it registered in my butt.
More recently, I had another long standing relation with Déborah, a ladyfriend, much younger than me, who also shared my interest for rectal temperature.
When the Civid erupted, she argued that, being in my late sixties, I was at risk for the virus and she moved to my place to take good care of me. Then, , she decided that we would take eachover's rectal temperature, stark naked of course, on our respective lap, every day, first thing in the morning. And so we did and it was a lot of fun. Unfortunately, Déborah dumped me 3 years ago and let me alone to take my temperature.
