You probably think you know the basics. Honestly, most adults do. We grow up hearing rumors in locker rooms or scrolling through confusing threads online, assuming we’ve got the mechanics and the biology of human intimacy figured out. But when you actually sit down and look at trivia questions about sex, the gap between "common knowledge" and biological reality is massive. It’s kinda wild how much misinformation survives even in the age of instant Googling.
Did you know that the average duration of intercourse—specifically the time from penetration to ejaculation—is significantly shorter than what movies suggest? A study led by Dr. Brendan Zietsch from the University of Queensland tracked 500 couples and found the median was just 5.4 minutes. That’s a far cry from the marathon sessions depicted in pop culture. This is exactly why trivia matters. It strips away the performance anxiety and replaces it with cold, hard, and often hilarious facts.
The Biology We Usually Ignore
Let’s talk about the clitoris. For a long time, medical textbooks barely gave it a paragraph. It wasn't until 1998 that Australian urologist Helen O'Connell used MRI technology to map the full structure, revealing that what we see on the surface is just the tip of the iceberg. Most of it is internal. This shouldn't be a secret, yet it remains a staple of high-level trivia because the education system basically skipped over it for decades.
Hormones are another area where people trip up. You’ve likely heard of oxytocin, often dubbed the "cuddle hormone." It’s released during touch and orgasm, helping create that sense of bonding. But it’s not just a "feel-good" chemical; it also plays a massive role in childbirth and breastfeeding. Evolution is efficient like that. It uses the same chemical tools for pleasure as it does for species survival.

Then there’s the "death erection." Yes, it’s a real thing. Technically called terminal priapism, it’s a post-mortem phenomenon observed most frequently in victims of hanging or violent deaths involving the spinal cord. It’s a grim bit of trivia, but it highlights how much of our sexual physiology is tied directly to the nervous system rather than just "being in the mood."
History’s Weirdest Intimacy Facts
If you think modern dating is complicated, look at the Victorian era. There’s a persistent myth that they were so repressed they covered piano legs because they looked too much like human limbs. That’s actually a joke from a travelogue that people took literally. However, they did invent the vibrator in the late 19th century—not as a toy, but as a medical device. Doctors used them to treat "hysteria" because manually massaging patients was, understandably, exhausting for the physicians' hands.
- In ancient Egypt, some forms of contraception involved crocodile dung. The acidity was thought to act as a spermicide.
- The Kama Sutra isn't just a book of "positions." Only about 20% of the text is actually about sex; the rest is a philosophy guide on how to be a good citizen and live a balanced life.
- The word "gymnasium" comes from the Greek gymnos, meaning naked. Because that’s how they worked out.
History is messy. It’s not a straight line from "prude" to "liberated." Often, ancient cultures were more open about body parts and functions than we were in the mid-20th century.

Common Myths That Need To Die
One of the most frequent trivia questions about sex involves the "G-spot." Named after Ernst Gräfenberg, its existence as a distinct, anatomical "button" is still hotly debated among researchers. Many modern experts, including those published in the Journal of Sexual Medicine, suggest it’s not a separate entity but rather an extension of the clitoral network and the vaginal wall working together.
What about aphrodisiacs? People swear by oysters, chocolate, and chili peppers. Science says... mostly no. While oysters are high in zinc (which is good for testosterone), you’d have to eat a mountain of them to see an immediate "spark." Most aphrodisiacs work via the placebo effect. If you think the expensive truffle pasta is going to make you more amorous, your brain will likely comply.
Size is the big one. Everyone asks. The British Journal of Urology International conducted a meta-analysis of over 15,000 men worldwide. The average flaccid length was 3.6 inches, while the average erect length was 5.16 inches. The "six-inch standard" is a social construct, not a biological average.

The Evolution of Connection
Why do we even have sex for pleasure? Most animals don't. Outside of humans, bonobos, and dolphins, most species have very specific mating windows. We are "continuous breeders." This evolution suggests that sex serves a secondary function: social cohesion. It keeps the "pair bond" strong enough to raise offspring that take a ridiculously long time to become independent. Human babies are basically useless for years. We need a reason to stay together.
- Sperm Competition: Some evolutionary biologists, like Robin Baker, argue that the shape of the human anatomy is designed to displace the "material" of rivals. It's a controversial theory, but it shows how deep the "trivia" goes into our very architecture.
- The Orgasmic Gap: Research consistently shows that in heterosexual encounters, men reach orgasm significantly more often than women. However, in same-sex female relationships, that gap almost disappears. This suggests the issue is often technique and communication rather than a biological "difficulty."
- Synchronization: You might have heard that women who live together synchronize their periods. This is known as the McClintock effect. Interestingly, later large-scale studies (including data from period-tracking apps) have largely debunked this. It's usually just mathematical coincidence.
Beyond the Physical
We can't ignore the brain. It is, technically, the largest sex organ. The hypothalamus is the control center, regulating the release of gonadotropins. When you feel "butterflies," that’s your sympathetic nervous system kicking in—the same system responsible for "fight or flight." Your body basically treats a massive crush like a life-or-death situation.
Pheromones are another tricky subject. While they definitely drive the mating habits of moths and dogs, the evidence for human pheromones is surprisingly thin. We don't have a functional vomeronasal organ (the thing animals use to detect pheromones) in the same way. We rely much more on visual cues, voice pitch, and—believe it or not—scent, but in a more "you smell like someone with a different immune system than mine" kind of way. This is known as Major Histocompatibility Complex (MHC) signaling.
Putting the Trivia to Use
Knowing these facts isn't just about winning a pub quiz. It’s about lowering the stakes. When you realize that "average" is much broader than what’s on screen, or that the history of human intimacy is full of crocodile dung and medical vibrators, you stop taking it all so seriously.
- Audit your sources. If you’re getting your "facts" from social media influencers, cross-check them with sites like PubMed or the Kinsey Institute.
- Talk about the weird stuff. Normalizing these conversations reduces shame. If you can laugh about the fact that ancient Greeks exercised naked, you can probably talk to your partner about what you actually like.
- Focus on the brain. Since we know the placebo effect and the nervous system are so powerful, prioritize mental comfort over physical "perfection."
Next time you encounter trivia questions about sex, remember that the "truth" is usually more complicated—and more interesting—than the myths. Real intimacy is built on understanding the weird, wonderful, and sometimes gross reality of being a biological organism. Start by looking into the actual research on the "bonding" chemicals like vasopressin and oxytocin to see how they impact your long-term relationships.
