How far to you insert the rectal thermometer

How far should you insert the rectal thermometer to get the most accurate reading?

Just curious

This question has been asked and answered in a number of threads but basically if it’s a young child about an inch and a baby maybe a half inch and in a teen or an adult about half the length to the thermometer so about 2 inches.🌡️🧴🧻

@Kenw thank you

@Luvbottomtemps I'm afraid that Kenw has advised you incorrectly. Insert the bulb end of the thermometer into the anal canal no more than 1 inch (2.5cm) is what is recommended in a clinical setting and it advisable to use a "mercury-free" rectal thermometer or a digital thermometer.

When I am taking a temperature and inserting a well lubricated rectal thermometer, I like to leave at least a couple inches sticking out so I have something to hold on to while I twirl it and use it to slowly and gently fuck his tight ass. I really enjoy watching the thermometer, in addition to other fun things, disappear into his bottom.

I’ve experimented with this, and I found that barely inserting it into the anus, or deep enough for it to barely stick out of your cheeks, gives the same temperature reading. The vintage European rectal thermometers, unlike the American versions, were not designed to be inserted beyond the bulb, or so it seems. You have to find the sweet spot. Inserting it too deep can be hazardous. For an average adult sized rectum, you can’t really feel the thermometer after it goes in, unless you physically move it around. I’ve only known two adult women who had tight buttholes, and claimed that it was painful, even with Vaseline.

A little deeper than it is now... No, that's too deep... Now you're not in far enough... Nope, now you're too deep again, turn it a bit and pull it out a little... No that's too much. Push back in a bit... Don't forget to twirl to spead the vaseline around...

My insertion depths were correct for the American style glass Mercury thermometers a lot of the older medical books. Talk about those distances.

Far beyond what's recommended for regular use 😜

HEY @Allie80 .... how about a 18" double dildo disappearing. Pushed all the way in.

About 2 inches but ensure enough sticking out to remove and to play with it. Also some asses you can insert deeper as they are small and others less so as the cheeks are big and it gets lost in them!

One inch, an inch and a half, don't insert too deeply! Blah blah blah..

No need to be so anal about it....

My measurement is usually a combination of the resistance I feel coupled with a depth that allows the thermometer to be supported. I have taken some rectal temperatures as part of play. If their bum takes it smoothly I will go as far as required for it remain place on its own. Usually just shy of half way

All the way in

Stop before you hit the uvula

My ex liked to see me jump or try to resist it, so after a good spanking and I was over his knee he wouldn’t push it in fast and as deep to watch me try to run away. Once it was in, he would twirl it around and pull it in and out until I was soaking.

Sometimes I have my temp checked in my urethra. It is sterile and only goes in 2 inches. It's a lot lower than my rectal temp.

Usually about 1/3 the length of the thermometer

Oh.. reading this. I get the feeling that you are taking my rectal temperature in this way. That would be the way I like to submit to a rectal temperature.

I saw an article about placing a rectal thermometer far into the rectum, to check your circadian rhythm. I had never heard of this before. I like to feel it as much as possible, and I think the deeper, the better.

About 1 inch to 1.5 inches is what I have always used...

...If you feel a tickle in the back of your throat it is in a bit too far...D'oh!

If you're taking your rectal temperature to get an accurate reading, I'd say you need to insert the thermometer no more than an inch. But I take my rectal temperature for erotic pleasure so I insert more than three quarters of the length of the thermometer in my ass. When taking other guy's rectal temperatures, I have often inserted the thermometers deeper so that just maybe a quarter of an inch is peeking out of their manslits.

European glass thermometers have a thin tip and a thicker body. The tip is meant to be inserted fully, but normally one does not start inserting the body though one may do it for play; and some members report their parents did it.

Its a closed cavity so any depth works. Personally, I prefer deeper inside.

If you’re making images of someone getting an RT, depth of insertion is certainly a consideration.

My Dom is reading this thread. I know what's coming!

My digital thermometer gradually expands to the part that holds the display. I insert it to the point where thermometer reaches its largest width. That is about 3 inches.

It depends on the thermometer. If I'm using a Geratherm or other mercury-free to get an accurate temperature, I just insert the thin tip, until the thick part touches the anus. For play time, thick part and twirl it in her bottom. Digital, or straight-wall glass thermometers, I usually go in about an inch or two. If I'm using a candy-making thermometer for play, I insert slowly, letting the conical shape of the tip gradually spread the anus, until the thick part is inside her.

I insert the thermometer (a classic glass one) very deeply into my bottom. Almost its entire length. So much so that only a very short tip sticks out of my anus, and when my buttocks are relaxed, the thermometer is almost completely invisible. This turns me on like crazy!

The large glass thermometer was inserted almost completely into me
