At 70, I have been having a strong rectal temperature fetish thoughout my all life .
As a teen and young adult, I was very shy with girls and I masturbated a lot, often with a thermometer up my ass.
I eventually found my first girlfriend ( or she found me) at 21. She had had many lovers and she tought me a lot, but the day I brough a rectal thermometer with me to spice up our relation, we allmost broke down. She was very shocked. She considered rectal temperature as something disgusting and shamefull, So during the four years we were together, she allways refused to let me take her temperature or to take mine.
Fortunately, my second girlfriend was the exact opposite. She was very much into medfet and she had told me that she would accept to have sex with me, but on her terms. So, every time we were to have sex, she imposed a medical exam on me, me stark naked, her with her clothes on. This exam included much stething, then concentrated on my penis and testîcles and allways ended with her taking my rectal temperature on her lap After sex, we often took eachover's rectal temperature and it was allways a lot of fun.
Following this period, I would say most of thé women I lived with ( not so many) have shared my rectal temperature fetish and we had a wonderfull time.
I would just mention a strange relation I had a longtime ago with a lady whose rectal temperature fetish was even stronger than mine. We spent nights taking eachover's temperature in every possible position, but she allways refused any kind of sex. She said our temperature taking relation was so extraordinary, so out of this world, that ''ordinary'' sex would spoil it. I was a bit frustrated and, 30 years later, I still fantasy about making love to her, as she was the most attractive and classy woman I ever met, wearing designer clothes or naked with a thermometer up her butt.
