Your post-smush cuddle could come with a surprise.

Got the runs? Your man’s semen might be to blame.

We’re 100 percent serious. That hot and steamy session between the sheets can result in a serious relationship with your toilet.

A chemical compound found in semen called prostaglandins can actually give you cramping and diarrhoea, says Teresa Hoffman, an obstetrician and gynaecologist.

Hoffman breaks it down: Prostaglandins cause smooth muscles, like those in your uterus and intestines, to contract, and when your intestines contract too quickly, you can get diarrhoea. So if you have unprotected sex, some of his pesky little prostaglandins are absorbed through your vagina and venture to you your colon (conveniently located right behind your uterus) and cause the runs.

BTW: We actually produce prostaglandins during our menstrual cycle, which is why you may notice that you have diarrhoea before you get your period. In fact, getting it on in the days before your period might mix your prostaglandins with his, which could make those poop symptoms much worse, says Hoffman.

The human body is a magical thing.

While it seems to make sense that ingesting semen during oral would get the No. 3 juices flowing, too, Hoffman says your stomach acid actually breaks it all down pretty well. The problem is more likely to occur when you have a lot of semen pumped (literally) into your uterus, like when you have a lot of sex in a short amount of time.

Hoffman says this isn’t something that happens often, but if you notice that you’re having diarrhoea or significant cramping in your uterus a few hours after sex, ask your guy to wear a condom or pull out before he finishes. “That will help you see if it’s the prostaglandin effect,” says Hoffman. If you notice a link between your poop and when you have sex, talk to your doctor and tell him or her what you’ve noticed. Your doc may give you a sonogram, just to make sure something else isn’t going on.

But, Hoffman says, you might be able to handle this on your own. “It may just be a matter of not having him ejaculate into your uterus,” she says. Makes sense.
