Thermometer kept in place for longer than the required time

Usually the glass mercury thermometer is left in place for three minutes. That has been my experience . About a week or so back( wrote about it) a visiting masseuse took my rectal temperature with a mercury thermometer and she left it inserted five minutes. What’s a minute or two more?

I recall one thermometer used in my childhood was labeled "maxima à la minute", which should mean 1 minute is necessary. My mother was retrieve it ~3 minutes after insertion.

Yes I do currently have a Frida Baby 3 in 1 thermometer in my bottom while I have my Huggies diaper off and resting under my bottom using the long end of the probe as it registers feels really good and running in rectal mode its super accurate at measuring my temperature.

Even better if the doctor keeps his hand on your buttocks or fiddles with the thermometer while it is registering.

I have one of those Welch Allyn electronic thermometers with the thick, disposable plastic sheaths. I like that even better than glass.

It only takes a few seconds in the rectum to register. But if you hold the button down, it will shift into a "monitor" mode that will display the temp for as long as you choose to leave it in.

That’s why I either don’t turn it on or use the glass one that way if it not on after 5 minutes I would be like oh snap forgot to turn it on or with the glass one there was no timer on it

Even better if the doctor keeps his hand on your buttocks or fiddles with the thermometer while it is registering.

Even better is if the doctor actually keeps the buttocks parted exposing the anus for the entire duration and indulging in small talk with the patient. I have received feedback that getting a whiff of air on the anus and knowing that the doctor can see for the duration that they are chatting is super embarrassing.

That's nice as well. I do love a little breeze across an exposed anus.

I leave it in while I masturbate. A great feelong.

When I was a kid, the rectal thermometer was usually left in place for 3 minutes, either at home, doctor or hospital. I was always told to hold still for that amount of time which seemed long as a kid, watching the clock make 3 sweeps of the second hand and then the thermometer was removed, read, and usually announced to anyone in listening distance. 3 minutes became too short as I got older so since I was about 16 or so, I started to leave it in for 5 minutes. To this day, I still watch a timer as it counts down 5 minutes and remind myself to hold still "like a good little boy".

I leave the rectal thermometer in for 5 minutes.

Damn dude, we're definitely on the same page!!

Standard method is 3 minutes. When I'm taking a bottom temp I've always gone for 4 minutes just because I like to see that thermometer in the hiney.

Darn! My Filac 3000 ES does it in 20 seconds. Upgraded models have a long temp option. I try to get the long 1 minute RT by using a trick. Placing into rectum quickly and then removing for 10 seconds bring on the long temp mode. It’s the king of all RT

I often fell asleep with the thermometer in my bottom. I don't remember how long it was inside me.

The European glas thermometers require 5 minutes. It was/is a long time i can tell you. Don't know if it was kept in longer.

The Geratherm that I use most of the time requires a minimal measuring time of 4 minutes. My minimum is 5 minutes to be on the safe side but often I reach 10 minutes or longer.

Only when I been bad my Nurse keeps it in longer than normal time...suppose to teach me a lesson she says but all it does for me is makes me very happy inside:-). Usually 10 minutes with glass thermometer in diaper position with a red sore bottom most times.

I use a glass rectal thermometer. When I go to bed at night I insert it in to the end the thermometer until it touches my body. In the morning I remove it. I love the feeling of the old glass mercury thermometers

Usually I leave the thermometer in around 3 minutes but it can definitely be left in longer depending on who I am playing with 🍑🌡️😈

That could result in a nice job for an ER doc!

Leaving it in while you sleep is very dangerous.

Would love this on the receiving end… the longer the wait, the more time to feel exposed, embarrassed, uncomfortable, etc. Would also be great to be told I must keep the thermometer in for longer (or have it reinserted) because I was squirming or clenching, preventing an accurate read.

I don't tend to keep track of how long a thermometer is left in my bum; I just enjoy the rush that comes from submitting to the doctor and the feelings felt from the thermometer filling up my glory hole, if you will.

While staying inserted, it is nice to feel the doctor tap the thermometer from time to time, especially after confirming it has been pushed in as far as is needed 😀

Being in such a vulnerable postion, too, knowing the doctor is visually taking in the entire scenario [and possibly storing mentally for their satisfaction later] is absolutely TITillating, too!

My experience has been 3 - 5 minutes taken by a nurse. I have been positioned on my belly or side, the later as I got older. I have also had the Welch Allyn type which registers very quickly but the probe does seem to be longer.

For me, the experience is not just how long will it take to register but the experience of first being told and then having to assume the position while having to lower my briefs or already being naked. That moment is very personal; thoughts and emotions are crazy and become heightened as my cheeks are spread open. From there, it's clear that I will have to submit and soon feel the thermometer penetrating my anus. It truly is a mix of vulnerability as well as physical sensations of the nurse holding the thermometer in position. Her hand may rest on my butt cheeks adding to my submissiveness. The development of an erection was common if required to be lying on my belly. I am convinced that it was one way for the nurse to confirm the onset of puberty.

The magic number for a glass mercury thermometer was always at least three minutes for a medical measurement. I have discovered over the years that sixty seconds is more than adequate for it to accurately register.

Length of time is of course always up to the person doing the taking for recreational temp taking. I have found that taking someone’s RT more times during a session is more satisfying than just once for an extended time.

1. Withdraw

2. Read

3. Wipe bottom

4. Clean thermometer

5. Shake down

6. Reapply lube

and Repeat

At least once when I was about 15, I was lying on the table getting my temperature taken. Another nurse entered the room and told my nurse she was needed to assist for an injection in another room. She told my dad she would be right back, and asked him to hold the thermometer in place in my rectum. She must have been gone about 20 minutes or so. I told my dad it was more than time for the thermometer to be taken out. He agreed, but said we needed to wait for the nurse to return. He continued to hold it in until she came back.

Same just the feeling is a flood of emotions for me. Knowing that when it’s time to take a rectal temperature I surrender myself as my pants and Huggies diaper are removed while placed in the diaper changing position. Within the next minute I feel my cheeks part as the lubricated thermometer slow pokes and prod my bottom and slowly goes in deeper and deeper until it stops and sits there. The sheer sensation of the probe sliding in gives me a mix of emotions of excitement and euphoria. Knowing that two things one I’m getting a core accurate temperature and two being treated like a baby. For me I usually keep the thermometer inserted well past the recommend time if it’s a manual I keep it in there sometimes for a good 30min to a hour and twist and twirl it. If it’s a digital thermometer such as the Welch Allyn SureTemp Plus 692 model I keep it inserted nice and deep for 15 min in monitor mode as it constantly measures my temperature. Just thinking about taking my rectal temperature gives me a hard on while I’m in my Huggies diapers.

I have posted about this girlfriend of mine, Maria, more than 40 years ago, who was very much Into medfet and imposed on me every time we were to have sex a physical ending with her taking my rectal temperature on her lap.

The fact is that Maria never told me how long she left the thermometer in place. I would guess something like

10 to 15 minutes And she never told me what the thermometer reading was. That was how she expressed the fact that she was in control.

Leaving a thermometer in my rectum for an unknown, extended period of time is always very exciting for me. I enjoy having a doctor or nurse examine other parts of my body with the thermometer inside me, occasionally readjusting the thermometer by moving it in and out, tapping, or twisting it. Always been an important part of my medfet play.
