What I remember most vividly about my rectal temps as a little girl is a sensation of discomfort up my bum. Not actually pain: it was more like feeling unconfortable sometimes I felt like...pooping! If I insert a glass thermometer now (which was what both my mom and my pediatrician used on me), I can barely feel it ? I know, a kid's anus is much smaller and even something thin like a thermometer could cause discomfort (or..pleasure, but it wasn't my case!). Now, my question is what to use to feel the same sensation as a kid? I tried dildos and vibrators (different sizes and materials), I like them but they don't make me think about a rectal temperature taking, which is my target ?
