I am now 70 and I think I can say that thoughout my life, my rectal temperature fetish came to life on several occasions.
Christine, my first girlfriend who took my virginity when I was 21, was absolutely opposed to rectal temperature. She found the whole thing disguting and she never accepted to take my rectal temperature or to let me take hers.
Four years later, Maria, my second girlfriend, was just the opposite. She was very much into medfet and she had set the rule that, everytime we were to have sex, she would give me a comprehensive medical exam that included a lot of stething and allways ended by her taking my rectal temperature on her lap ,
Later, most of the women I have lived with ( not so many) have shared my fetish and we used a lot therlometers in our sex games.
I must pay a spécial tribute to Eve, a lady I had a several months relation with , who had a stronger fetish for rectal temperature than me, and accepted to take my temperature or have hers taken in any position, but refused any kind of sex. We spent nights of passion together but she never touched my penis and I never touched her vagina. She said our rectal temperature sessions were so extraordinary that having ''normal'' sex would spoill our relation. On my part, I still have a fantasy of having sex with her, as she was the most attractive lady, wearing an evening dress or naked with a thermometer up her butt.
Growing older, I had a 10 years long fantastic relation with Deborah, a younger colleage in my lawfirm who shared my interest for rectal temperature. During the pandemic, she moved in with me. She said she wanted to take care of me, old man at risk with the virus. So, every morning, we took our respective rectal temperature on eachover's lap first thing in the morning , and we had a lot of hot sex
Unfortunately, Deborah dumped me a year and a half ago and I am now on my own to take my temperature. So I do feel a bitt lonely and sad. But taking your rectal temperature alone can still be fun…. and I still have my memories.
