I had an ex-girlfriend who really got off on having her temperature taken rectally.  It had to be done a certain way.  She would lie over my lap. I would pull her panties down to between her butt and knees; shake down the thermometer; spread her cheeks with my forefinger and thumb; and insert the thermometer into her rectum.  After doing this about a half dozen times or so, she was soaking wet and really ready for “Normal” sex.  I have never met anyone else with this particular fetish.  Except for this fetish, she was normal is every other way.  Has anyone else experience anything like this?
