Is KY or Vaseline better to lubricate the rectal thermometer

I definitely prefer KY

Hands down (And Bom Bom UP!!) Vaseline, all the way.

KY may be easier to clean up the rectal thermometer or enema nozzle, but Vaseline is the gold standard in my mind. My mom used that exclusively. If you open the Vaseline jar, you would see a bunch of wholes from where the thermometer had been lubricated prior to going in my bottom or one of my siblings. Also, it was used when we got the enema bulb which was quite frequent as prepuberty kid.

Definitely a personal preference but I prefer Vaseline but I’ve had multiple people I’ve prefer KY. Vaseline just gives that extra cool and thick feel that gives you that shock. Vaseline is very smooth and using that can REALLY help the thermometer slide right in

I’ve had both used on me and enjoy them both. In the days of glass thermometers Vaseline was always used in hospitals and doctors offices. When they were replaced by digital thermometers KY was the lube of choice. For me Vaseline brings back good memories but the thermometer is much easier to clean when using KY or other water-soluble lubes.

Vaseline on a rectal thermometer is hot and sexy, the way it slips in the butt, without any effort, and drips and glistens from the body heat, when removed. KY jelly, is clinical, but not as messy to clean up. It also looks sexy on a thermometer. Vaseline is great for anal sex too.

K-Y and rectal thermometers are a good combo. Surgilube is also used when taking a rectal temp.

However, for inserting an enema nozzle or tube several times that result in multiple releases, Vaseline's petroleum base lubes and coats the anus much better – and it's more soothing – than water-based lubes such as K-Y and Surgilube.

Have had SO’s in the past that went wild over Surgi-lube at their annuals. Coming home dripping with it, squishing between their cheeks and labia was always fun.

Vaseline is more fun for anal probing and thermometer play. We use it alot. However I would not use it for sex again as once some went up my urethra and caused alot of pain.

Maybe it is because of memories but I am very fond of the faint smell of Vaseline so I would not like it if hubby woukd use something else, although I have to admit the use is not strictly thermometer limited.

I definitely prefer ky, gives it more of a clinical approach

My dad always used Vaseline when preparing me for rectal temps and enemas .

We’re all different, and we have personal preferences, but after 20-some years I still remember lying in bed shivering from a fever and seeing my husband hanging a full enema bag over me. On my nightstand next to the bed, he had placed a jar of Vaseline.

Seeing those two images, the enema bag and the Vaseline, it just seemed like they were meant to be together. I wanted to lie there and savor the moment before I had to turn onto my side and shed my nightie bottoms. I was feeling enjoyable tinges already with that image. That memory has stayed with me all these years.

I think that whatever lubricant you grew up with influences later preferences.

Born in 1968 As a child of the 70’s early 80’s I say Vaseline was the primary lubricant used my my mother and pediatrician for suppositories and rectal temperatures I can’t recall ever getting an enema

In my personal opinion, Vaseline is my preference for lubricating a rectal thermometer. Taking my rectal temperature is all about recreating childhood experiences. At home and at the Dr. or hospital, the thermometer was lubricated with Vaseline. After 3 minutes, the thermometer was removed, leaving some of the Vaseline back there. The warmth of my feverish buttcrack would melt the Vaseline and it would become slick and squishy. At the time it would be mildly uncomfortable, especially when walking home from the dr. after a well visit. If I was sick at home when my rectal temperature was taken multiple times a day, If I got up, for any reason, I would feel the slickness in my buttcrack. At the hospital, it was pretty much the same deal. I would be confined to bed, had my rectal temperature taken every few hours and I remember felling that sensation when I got up to use the bathroom. I still use Vaseline to lubricate my rectal thermometer and other medfet items and the feeling it leaves behind (all day if I use it in the morning) and I'm the only one who knows it is a big turn on for me.

Maybe it is because of memories but I am very fond of the faint smell of Vaseline so I would not like it if hubby woukd use something else, although I have to admit the use is not strictly thermometer limited.

- so if you are a fan of " smelling lubricant's -, maybe have a try with " WICK ", , an also good smelling, as stimulating your private part's in never expecting manner !!

I actually had a colonic therapist who used vegetable based shortening as the lube. Being as it was organic (sort of) I guess there was no harm in using it as a lubricant. Went to her for over six years and never experienced any negative effects.

I like Vaseline for everything. Rectal thermometers, enema tubes, anal plugs, vibrating anal plugs. It works great with all of them. I just love dipping each of them and inserting a smear on each tip of each into my rectum. Such a great feeling. If there is extra Vaseline around, I use it for a massage on my butt cheeks!

As a doctor, I prefer to use KY or Astroglide for rectal temperature taking or rectal exams.

KY is nice for easy clean up, but its almost too slippery. Vaseline has that great smooth feel going in, yet allows the nozzle to remain comfortably in place. KY is so sllipery that things tend to fall out pretty easily, even of their own weight. However this seems like a subject that could use a lot more research, so I will keep comparing them as frequently as possible. All in the interest of science, ya know!

I agree on Vaseline but my only issue is if it gets on bed sheets or other surfaces it can stain them badly. I like anal play and Vaseline is great as it means you can go longer and the sensation is amazing.

For anything anal, such as thermometers, enema nozzles, or butt plugs, I much prefer Vaseline because the water based lubricants such as KY wash off too easily and quickly. The exception is deep lube such as a colon tube which I squirt in some water based lube first. I have tried silicone lubricants but I am not a fan. Of course, nothing but water based lubricants in the vagina.

I've taken a lot of rectal temperatures at both home and as a nurse, and IMO Vaseline is way better when inserting any kind of narrow object like a thermometer. The thicker viscosity of petroleum jelly helps prevent a thermometer becoming snagged in the delicate creases at the entrance of the anus. Water based lubes like K-Y or Surglube are better for larger objects like enema nozzles, proctoscopes, and colonic speculums.

While individuals have their own preferences which is their choice...... some key facts to consider :

Petroleum jelly (like Vaseline) is an oil-based, thick ointment that traps moisture and protects skin. K-Y Jelly is a water-based, clear personal gel meant to ease friction during sex or medical exams. They serve very different purposes and are not interchangeable, especially for intimate use.

Key Differences

• Base Material: Petroleum jelly is oil-based; K-Y Jelly is water-based.
• Condom Safety: Petroleum jelly breaks down latex condoms in seconds and causes leaks. K-Y Jelly is safe to use with latex condoms.
• Body Impact: Petroleum jelly is hard to wash away and can trap bacteria or cause vaginal infections. K-Y Jelly is water-soluble, washes off easily, and is body-friendly.
• Skin Use: Petroleum jelly works best as an external barrier to heal dry skin, chapped lips, or minor scrapes. K-Y Jelly works best for internal and external intimate lubrication.

Absolutely KY. Its more clinical

I’m an equal opportunity lube user. Both seem good to me.
