Rectal temperature and sex

Have you ever tried having sex or masturbating with a thermometer in your rectum?

I tried it several times when I was younger. I was surprised that the readings did not rise very much.

WOMEN MUST NOT DO THIS.

The septum between the rectum and vagina is extremely thin and pressure of the penis in the vagina can easily break a thermometer during sex, resulting in severe, penetrating injury to the rectum and vagina.

Its probably not so safe for the men either.

Never tried it during sex, for pretty much the same reason that Switchableusie stated above, though I have tried masturbating. And no, it doesn't raise the temperature very much (0.2 C or so), but it sure feels great. What does rise the temperature though is a hot shower. I can get as much as a 1 C difference from that.

I would like to try this, but I agree with svensson that the plastic electric therms might be best b/c any sort of strenuous movements could cause problems. Best to be safe.

My wife and I tried this the other night. She took my rectal temperature just before we had sex...it read 99.8F. Immediately after intercourse she took it again...100.1F. She told me it wouldn't go up much anyway because sweating is where most of the excess heat gets lost.

Slim88, thank you for your post,

My idea, and what I achieved several times with a girlfriend a long time ago, was to have both of us a thermometer in our rectum(s) during love making. Of course,we used plastic electronic thermometer to avoid the risk of breaking a glass thermometer in the course of having sex. As I am not really a fan of sex toys, I felt kind of uncomfortable during the love making. My girlfriend was disappointed that the reading did not go up very much. Once, we tried it having anal sex and obviously, she could not have a thermometer in her rectum, and my readings there were still as low.

FYI, the reading for the first experiment we made were as follows ( in Celsius, I leave you with the joy of converting in Farenheit):

my gf: 37,2 before sex, 37,6 just after, 37,3 one hour later, me: 36,9 before, 37,5 just after, 37,0 one hour later.

To draw a comparison, after a lengthy tennis match in a hot Italian afternoon, my temperature reached 38,2 just after the match and back to 37,2 two hours later.

For me it's an erotic game, so it is very likely to be followed by sex ... above the anal

Sometimes during sex I'll take a rectal temp

I had a thermometer in my butt while my partner was sitting on me.We had to be very careful because it was glass thermometer but it was one of the best orgasms i've ever had.

Must admit I'm struggling to see the appeal of rectal temperature taking. Don't get me wrong, I love all sorts of anal fun, fucking, butt plugs, suppositories & enemas to name just a few, but surely a thermometer is too small to feel properly even in the tightest of butts? In my bathroom cabinet I have an old mercury thermometer but the thought of sticking a slim glass tube full of toxic liquid heavy metal in my anus, or even in my mouth seems altogether a bit hazardous, never mind bouncing about having sex with one stuck up you? I can understand the humiliation aspect having a dom nurse or partner ordering you to bend over & spread 'em....but maybe I've missed something?

Unless I’m feeling really sick, I always masturbate with the thermometer up my ass. I twist and turn it, take it out, sniff it, and repeat, until I orgasm like a rocket going off! I get orgasms that are so intense, that they can probably be felt at least 5 states away.

For risk concerns, I have not attempted to masturbate or have sex with a glass thermometer inserted in my rectum. That said, the experience of having a rectal thermometer inserted does cause me to become erect, especially if lying on my belly. My preference is a glass thermometer rather than the digital probe as it always slips out. Staying true to my recollection of past childhood and teenage physicals is an important source of my fetish. I guess that I prefer the intricate dance between doctor/nurse and the submissive patient who is about to experience a rather embarrassing and physically stimulating experience. Most of us never had anything inserted into our rectums until we had a physical. From thermometer to the DRE, it engenders some anxiety and for sure erections either then or later! How many of us pause to look at thermometers while at CVS? I am willing to bet most of us are searching for the one labeled "Rectal."

Me and my girlfriend have done this. We had sex doggie style after a shower and I inserted it in her ass and played with it as we had sex. She was really turned on by this and ended up with 38 degrees.

Earlier she gave me a blow job and inserted the thermometer in my ass. I exploded like nothing else!!!

Mostly during a b.j my girlfriend insert the thermometer in and hold it in pace

It makes my orgasm way way higher

And make me shiver for about a minute afterwards
