Chimpanzees, macaques, mice, and cats (pictured) still have them. But thankfully, somewhere along our evolution humans lost the part of our DNA that would have given men spiky, erm, enhancements.

In 2011 there was a widely reported case of a woman who suffered memory loss immediately after orgasm. “Both the patient and her husband stated that after climax she was unable to recall events of the preceding 24 hours,” reported the Journal of Emergency Medicine. “In addition, she had difficulty incorporating new memories.”

There are other known cases, too.

This study recruited 500 couples from five countries and measured the “intravaginal ejaculation latency time”, i.e. how long it took the male partner to come. The median was just over five minutes (with a range between 30 seconds and 44 minutes), and condom use did not change this.

(You will need to put the condom on your penis and not a random banana, mind.)

10. One type of medication for OCD can cause people to orgasm when they yawn.

A Dutch study found people had an 80% chance of reaching orgasm in an MRI scanner when they were wearing socks, compared with a 50% chance when they weren’t.

The BBC explains: “One half of the couple was asked to lie down, with their head inside a scanner, while their partner stimulated them manually to achieve orgasm. To aid the mood, the room lighting was dimmed and all noise distractions shut out.”

12. Women have wet dreams too.

According to a 1953 study by Alfred Kinsey, 37% of women orgasm in their sleep by the time they reach 45 years old.

According to the US National Bureau of Economic Research.

16. By their late teenage years, three-quarters of people have had sex.

According to the Kinsey Institute. And more than two-thirds of all sexually experienced teens have had two or more partners.

17. People aged 18 to 29 have sex an average of 112 times per year.

Yes, really (according to a 2002 US study, which is the latest data available on the Kinsey Institute website).

18. Men who cheat on their wives are more likely to die of cardiac arrest during sex.

People dying suddenly during sex does not happen very often. But when it does, it mostly happens to men who are having sex outside of marriage, “in most cases with a younger partner in an unfamiliar setting and/or after excessive food and alcohol consumption”, according to this statement by the American Heart Association.

19. It’s possible for couples to get stuck together during sex.
