The world is chock-full of urban legends. They can be scary, mysterious, or even hilarious. However, they’re just legends, so they can’t possibly be true, right?
As it turns out, these urban legends are actually 100% true. Interestingly, a lot of them are about sex—if this doesn’t make you uneasy about sleeping with somebody, we don’t know what will.

#10. People Have Actually Gotten Stuck During Sex.

While this nightmarish scenario might be the last thing any couple wants to experience, it unfortunately has happened multiple times in the past. According to medical journals, penis captivus (yes, it’s as painful as it sounds) involves intense spasms that can cause a woman’s vagina to clamp down on her partner’s penis during intercourse. As the man’s penis is usually engorged at this point, withdrawing becomes painful and nearly impossible. Luckily (kind of), penis captivus usually only lasts for a few seconds.

As of this writing, there is no legitimate scientific explanation for what causes the spasms behind penis captivus, though some blame witchcraft or consider it a punishment for the couple engaging in an illicit affair. Both of these are pure superstitions, however.

It’s an incredibly rare condition—only a handful of alleged incidents have ever been recorded. However, it might simply be massively underreported—as we can see from the video above, which details an alleged case of penis captivus from Nairobi in 2012, any such incident is bound to trigger an uproar and waves of sensationalism.

#9. A Girl Became Pregnant After Performing Oral Sex.

A story about a girl getting pregnant after performing oral sex on her boyfriend initially sounds like the stuff that urban legends are made of. In the case of a 15-year-old girl from Zimbabwe, however, it actually happened.

Recorded in the 1988 edition of the British Journal of Obstetrics and Gynecology, the incident occurred after the girl had been stabbed in the stomach by a former lover who caught her in the oral act with another man. Doctors at the hospital discovered that the wound opened up a hole her stomach near the rest of her abdominal cavity. They stitched both holes up and discharged her.

After 278 days, however, she returned to the hospital complaining of abdominal pain. Upon evaluating her, the doctors were surprised to discover two things: She had no vagina (merely a dimple instead), and she was carrying a full-term infant. A cesarean operation had to be performed to deliver the baby.

Since no vagina obviously means no traditional pregnancy, doctors concluded that the child had to have been formed by the sperm escaping from her stomach via stab wound and settling down in her reproductive area. Coupled with the absence of gastric acid during the initial operation, doctors believe that is what could have allowed this extraordinary pregnancy to occur.

#8. There Is A Pill That Can Cause An Orgasm.

Most side effects of drugs are dangerous, deadly, and just plain not fun. However, drugs like clomipramine prove that not all side effects are bad. The drug, which is supposed to be used as an antidepressant, has been shown to cause orgasms among patients who yawn after taking it. One woman even testified that she continued taking the drug long after it cured her of her depression.

As of this writing, scientists are still unsure how yawning could cause a drug—one proven to decrease libido, no less—to trigger an orgasm. In addition, not everyone experiences clomipramine’s orgasmic effects. In fact, it is estimated that only 5 percent of total patients can get an orgasm this way.

Besides the huge odds, people still have to contend with the myriad side effects commonly found in antidepressants, such as nausea, erectile dysfunction, and even hallucinations. In addition, not all patients who experience drug-induced orgasms have enjoyed the experience. One man even reported that he had to wear a condom everyday just to avoid smearing his pants.
