If it's unprotected sex, the most common cause is because of the semen. Semen produces a chemical called prostaglandins. Prostaglandins cause cramping and diarrhea because it causes smooth muscles in the uterus and intestines (so this can happen with males too) to contract. When this happens too quickly, that causes the diarrhea. So most likely it's this, but you can always check with your doctor if you're truly concerned.

Last night my boyfriend and I started to have sex for the first time. It was in and out, and then we had to stop. We used a condom and neither of us had *** even a little yet. Now I have diarrhea. It's not because of the semen, there was none. And it's not because of anal sex, we had vaginal. So why does it happen? I don't  know, but you're not he only one with the problem.

This apparently is not limited to heterosex community as a twink in LGBT community I have experienced (as I am passive partner in anal sex) sometimes a short duration of the  squits (diarrhoea). I am assuming this to be caused by rectal stimulation from sexual activity. If not, then what could cause this in gay males?

Thanx!

I get this most of the time, like the next morning. It sometimes takes hours to stop. Admittedly it makes me not want to have sex as much. I read somewhere that it could be cause by the prostaglandins in semen. This would make it true then for both hetero- and homosexual sex. It is something I am researching currently. I do have IBS also so maybe that makes it worse too. I'm glad I'm not the only one!

yea i have this problem too...but not all the time.  It has occurred on two occasions and both times it was only maybe two episodes of loose stool then constipation.  I have pain on the lower left side of my abdomen during sex.  Is this the same problem you have been experiencing?

Hi,

By diarrhea, do you mean multiple episodes of bowel movement or single episode of loose stool?

Individuals with irritable bowel disease can develop diarrhea after the stress of sexual intercourse.
Other causes of urgent bowel movement after ejaculation include prostate infection,
infection of the gastrointestinal tract, etc.

DO post a few more details of your condition so that a diagnosis can be approximate
