Did your mom/nurse know that you enjoyed having your temperature taken?

I do think mom noticed my enjoyment, she would always add more time. Then she would retake my temp every two hours

@Cardiologist87 That sounds good. Can I ask at what age this happened and how do you think she realised?

At the same time, from about 13-26 years old I developed a strong fetish for it which I will never understand.

@Fontana If you did not like the rectal measurement, it may be that it kept you very busy and was stored in your head as arousal. If you then tried it out during puberty, sexual arousal was added to this arousal and a fetish was created. That's nice, isn't it?
