Lube on thermometer or bumhole

Always on and INSIDE anus

It depends: If the thermometer—and I’m talking specifically about Geratherm glass thermometers here—is going to stay inside the sphincter for a little longer without me having to hold it in place, then no lubricant is needed. Otherwise, for the pleasure of both the giver and the receiver, the anus is always carefully prepared with Vaseline; that’s an integral part of the entire procedure.

I usually received a lubricated thermometer. Very rarely was the anus lubricated beforehand with a finger.

As younger kid I can only remember the thermometer was lubed, but through my teen years my anus was too.

At home it was often both. At the Dr it was most often just vaseline on the thermometer.

I always ask my caregiver to lube both with her finger and she always does and I love it.

I only had the experience when hospitalized as a kid a few times from pneumonia. They just did the tip.

It was always the thermometer that was lubricated with a generous amount of petroleum jelly.

My gf tends to add it to my anus first to tease me. She then removes the thermometer from its case (listen to the noise it makes), shake it down and insert it. Then I lie and enjoy.
