How far do you insert the thermometer?

I like having it in as deeply as possible, which in my case is almost the entire length of a classic, 4" glass thermometer.

Careful not to lose it in there ...

It should be inserted at least half the length of the thermometer in.

The thermometer should be inserted at least 2" but some patients might like it in deeper in which case hold the thermometer so it does not get lost inside.

When i'm taking my own, i'll insert as much of the thermometer as I can, usually ends up to be most all of the thermometer. If i'm taking another adult's, I do the same, but it usually ends up being at most 2/3 of the thermometer. It's always a very slow insertion with lots of lube, stopping if any resistance is felt.

Generally about an inch to inch and a half. At some point you feel a little resistance -- I don't try to go further. Don't mind seeing a fair amount left to protrude from between those cheeks!

Usually about half way or until I feel any sort of resistance.

Inserting a rectal thermometer all the way is not a good idea.

It could slip inside the sphincter. A slippery thermometer, buried in the rectum, having passed through a lubricated, slippery anus could be vary hard to grab a hold of to retrieve. Breakage could be a real danger.

3/4 is what I prefer. In re to letting it slip inside...not an issue to me. Keeping the top dry and free of lube...perhaps keeping it held between your fingers prevents such a problem.

I am careful not to loose the thermometer up my ass... Just some thing I do not saying everyone should.

Thanks,

Anywhere from 3/4 of an inch to one inch.

1.5 to 2 inches...

1" is safe

Probably between 1 and 2 inches.

I have a digital and mine goes in an inch and a half. Another inch and a half is proturding between my cheeks.

Mercury bulb

The thermometer was always inserted pretty deep,at least about half of the thermometer's length with my cheeks spread very wide.

I like the visual of the guy lying on his stomach with the thermometer sticking out from between his cheeks. So I suppose I usually insert it only 1-2".

That's an interesting question. Idealy, my "patient" would enjoy many different depths as I would be "adjusting" the thermometer several times during the procedure. Always with a slow calculating intent. Usually more fun that way! That's what most of us appreciate I believe.

Usually about 1 1/2 inch. Although that might change from time to time. I agree putting it any further in, you might regret that later.

Note NOT to do this with a 'normal' thermometer, ESPECIALLY a mercury bulb(!):

For research looking at core temperature, rectal temperature probes are generally inserted between 8-12cm beyond the rectal sphincter. This research backs this up, and finds no systemic differences for probes inserted more than 10cm - ie such devices should be inserted 10cm beyond the sphincter for the most accurate measurement. http://www.springerlink.com/content/8755100734275k10/

I would say 2'' maximum for adults.

I believe the thermometers being referred to in daiv's post are the kind used for people in ICU or surgery. It's like a small bulb shaped probe on a thin, silicone coated wire. It goes up the rectum much further than a regular thermometer probe because it's meant to stay in the body for prolonged periods. The advantage to these is a nurse doesn't have to disturb the patient for frequent temperature checks. My brother had one when he had spine surgery, and he didn't even know it was up his butt for 3 days until the nurse came to take it out. He said it hurt when she took it out though...."It felt like she pulled it out through my damn liver" I believe was his exact words.

For a normal adult using a typical glass thermometer 2" is fine. Someone let me know if you try the veterinary thermometer sold at agricultural supply houses like Tractor Supply. I'm curious about how it feels and how precise it is.

For 3/4 of the length, usually for a glass thermometer for rectal use is 8 cm long, insert for 6 cm.

My thermometer is 13 cm long, an i like to push it slowly all the way in. Should it go all in, just push as if you ware to poo and the thermometer is coming out easily. I love to keep it up my bum for at least 5 mimutes.

As far as it gan go...!!!!!!!!!!

I insert it about 8cm. Slightly less when I am lying face down on my stomach.

1-2 inches

Just enough for my anus to to hold it in without my the aid of my hand.
