How long do you keep the thermometer in place?

I usually keep the thermometer in place for at least 3 minutes.

I like to take my time leaving my hand on her fanny and listening to her whine as she squirms and begs me to take it out as I give the thermometer a little spin. Sometimes I remove the thermometer and tell her that she needs some medicine, inserting a suppository before she really knows what is happening or has time to object.

Until I get all hot-n-bothered.

3-5 minutes or so.

I like ladydocisin's answer "Until I get all hot-n-bothered.". Rectal temperature taking in our house is part of foreplay. Asking to take my wife's temperature is akin to asking for sex. We have been married for 43 years and she is my BBP Big Beautiful Patient. We agree she is going to have a doctor visit. We shower, turn the temperature up in the bedroom (if it is winter). She usually dresses in a sexy camisole and thigh highs. After a boob exam, with plenty of sucking, and a pussy exam, again plenty of sucking. She turns over for a rectal temp and a rectal exam, perhaps proceeded by a rimming. Her cheeks are spread and the thermometer is inserted and moved around a lot. It is removed and reinserted multiple times because I like to do that. Because she is going "bottoms up and spread open" like a good girl at the doctors office, she is "rewarded" with a nice pussy massage. This can go on for a long time. She will then submit to a rectal exam (or enjoy a pleasant anal/rectal massage, depending on one's point of view ) while still having her pussy massaged or vibrated. . I can tell you I really enjoy the view I have. But we certainly don't time the temperature taking, we just enjoy it. It is a highly erotic and intimate activity.

Keeps it in until alarm goes off on the unit, usually 2 to 3 minutes

As a nurse told me , But seriously, obtaining rectal temps is not recommended under most circumstances. Taking the temp rectally involves the potential of perforation of the rectum which can be cause pain . Two minutes should be sufficient though. Axillary (under the arm) is the preferred method. Place the tip vertically in the center of the axillary space and place the arm over the entire probe and hold it for approx 2 min or according to manufacturer's recommendations, unless its digital and then just until the indicator sounds.

5 minutes inside...

My play doc will keep in in anywhere from 5-20 minutes

About 5 minutes. Sometimes more or less

For standard mercury or Galistan thermometers, 3 minutes in the rectum is more than adequate to get an accurate reading. Some of the new Welch-Allyn digitals we have at the hospital require only a few seconds for a rectal reading, which I'm sure most of my pediatric patients are glad of.

Well put as usual nurse nikki

In the Scandinavian countries there was (and still is) tradition for taking temperature rectally. Simply because you get the most reliable result up your butt. This is done in hospitals and at home.

I remember when I was a child and my mother wanted to take my temperature. I was lying on the side (sims position), my mom lifted the buttock, and the anus was devoid. Then the glass thermometer was put in five centimeter up high (two inches). I really hated this. A thermometer of glass is cold and uncomfortable even with lubricate.

And then my contribution to this thread: My mom said "keep it in for five minutes". These five minutes were like five hours for me. I could not relax in that period, and my sphincter almost crushed the thermometer.

But today rectal temperature is "part of the game". It could be from 1 to 10 minutes. Either with my vintage glass thermometer or a modern plastic one. Yes, there is fun in the butt.

Another contribution: Textbooks from nursing school say two minutes for glass thermometers in rectum, and ½ - 2 minutes for modern thermometers.

Usually, three minutes is sufficient to obtain an accurate reading, but for play.... I like five minutes. And for play, when I had a second glass thermometer, I would always check the readings on both.

I always go 5 minutes and insert and remove slightly, rotate a little and tap the end of it to ensure good contact with the bulb for an accurate reading.

5 minutes if not more...depending.

5 min or more

Mom used a 3 minute egg timer, and I usually leave a thermometer in for 3 full minutes , or longer for RT play. I recall once when I was a kid and mom got a phone call while taking my temp i had the thermometer in me a very long time maybe 20 minutes or more.

My mom usually kept it in for the usual 3-5 minutes. She'd insert it, and then leave the room for a few minutes, leaving the thermometer to register, while I lay on my stomach on the bed. Occasionally, though, she'd get distracted by a phone call or something, and forget to come remove it for a while. Eventually, I'd call out from my room, "is it DONE yet?", and she'd appologize, and come back in and remove the thermometer and read it.

When I was a kid the thermometer was inserted for 3 minutes most of the time. Since I was 13 and started taking my own rectal temperatures, I always kept the thermometer in place for a full five minutes. I did mostly because I fantasized about a strict nurse wanting to be as accurate as possible (while experiencing maximum pleasure).

When I was a kid and had my temperature taken it was usually about 3 minutes. When I started taking my own rectal temperatures at about 13, I started taking them for a full 5 minutes. I fantasized about a strict nurse wanting to be very accurate. My fantasy and time inserted is still pretty much the same today and I do the same when I'm sick.

Five minutes usually.

3 minutes for reading - longer for play.

I would say 5 minutes is still the golden standard for a glass thermometer...

4 minutes. I watch the clock on the wall across from the bed.

Probably about five minutes, give or take a little...

Depends very much on the thermometer. Usually between one and five minutes.

Depends...sometimes it takes awhile for temp to register....as I'm directed to lie so so stil, on all 4's, head down, buttocks in air, my clitty gets some sweet attention, astro-gel, then probing fingers...;1, 2, maybe 3; thermometer gets turned....if I've been bad, 3 fingers remain in pussy, thermometer is removed, generous astro-gel to anus/rectum, made to slowly, slowy take large, jeweled butt plug....

For me, the best parts are going in and coming out, so I'll generally take it out after a minute. I've found its almost always within a tenth or two of where it would be if I did longer.

3-5 min
