No lubricant for self-taking R/T

I prefer vaseline over oil or water based types.

A drop of water or a quick pick works. Although, dry inserts works too. Glass thermometers rarely puts up resistance.

Vaseline all the way. I will occasionally use ky if I'm talking a quick temp but almost always prefer Vaseline. It is what was used in my childhood and just feels better for rectal temps than the super slippery KY Jelly.

When I was first experimenting as a kid, I wouldn't lubricate the things I'd use as thermometers 😂 it was quite an experience!

What are those unlubricated objects you experienced with, @Penny?

I can do it without lube,because thermometer is small for my asshole

@SadisticDaddy mostly pencils and markers, but I also played a little with damn near anything small and phallic shaped!

The feeling of an un lubricant cold glass thermometer is amazing

I never lubricant the thermometer

A rim job can be a great lubricant as well

Yes. I'm wholly unsure how my parents used to take my temperature when I was little, but I don't recall being given lubricant when asked to take my temperature. I just bore down to open the hole and gently inserted the tip.

My mom never used any lube. She just pried my cheeks apart really far apart to open my anus and stuck it in. She fid RTs that way til I was 13. Enemas stopped at that time as well.

When I was little and in yhe hospital, I don't remember the nurses using any Vaseline either.
