We’ve scoured the web for sex facts that will shock, surprise, and even challenge beliefs you’ve held all your life! You’re in for a treat. 🍭

Will this article make up for a lack of sexual education? That’s a hard no, but you’ll have plenty of inappropriate jokes to share at work functions, weddings, or your mother-in-law’s garden party. 😈 Or, it might just put you in the mood to test a few of these fun facts yourself.

If you knew all of these sex facts already then, boo, you’ve got a leg up on everyone else 😉.

Let’s start by busting a super common myth:

The egg actually chooses the sperm

Ever heard that the fastest sperm impregnates the egg? Well, that’s a complete myth. ⛔

It’s the egg that chooses which sperm is allowed in, and it’s not always the first one. The egg is finding the perfect match among the sperm. Shame the pickings are so slim, huh?

Sex facts about health 🏋️

You probably already know that happy, safe sex is good for you, but it’s not just the calories you’re burning 🥵.

For women, orgasms actually lower the risk of:

  • Heart disease
  • Strokes
  • Breast cancer
  • Depression

Also, while we’re talking about the positive effects of sex for women, did you know that the extra blood flow from being on your period might actually lead to a more powerful orgasm? 🤯 Just one more reason to take a break and enjoy yourself when you’re feeling crappy.

Women aren’t alone in benefiting from sex

Having four orgasms a week could reduce a man’s chances of getting prostate cancer. Not a bad thing to know!

And no, sex isn’t strictly necessary to hit that quota. Go do with that information what you will.

Sex facts about your… nose? 👃

So, we somehow found two sex facts about noses. 🤥

The first is that a good nose can make your sexual experiences better! That’s because you’re getting the full experience of pheromones like vaginal fluids and sweat. 💦

The second is about swelling, not smelling. You probably already know that sex makes genitals and breasts swell, but did you also know that your inner nose increases in size? Not Pinocchio levels or anything, but still…

Looking to have an orgasm? The key might be socks 🧦.

See, to have an orgasm, we need to feel relaxed and free of anxiety. If you have cold feet (literally) that’s going to be on your mind first and foremost. A pair of socks will make you feel all warm and snug, and might be the best way to get in the mood❣️

Sex might be the answer to cracking your novel 📖

Struggling to write, draw, sing, or do anything else in the creativity department? Well, go have sex! 😲

When you have sex, your body releases a chemical you’ve probably already heard of: oxytocin. That chemical makes you feel closer to your partner 🤗, and it also gets the juices flowing across all those different brain pathways. So, you can improve your problem-solving skills and spur some creative thoughts! Go figure.

Suffering from migraines? The answer is… also sex

Tension restricts blood to your brain and causes headaches.

When you have sex, you’re releasing tension, so you’re getting your body to fully relax, and might get rid of that pesky migraine.

It’s a self-cleaning system

There are two organs in the human body that are self-cleaning:

  1. Eyes
  2. Vaginas

Do you stick anything up your eye to clean it? No? Same principle applies to a vagina. It’s magic ✨

There’s more data in a single sperm that in a floppy disk

Actually, the comparison isn’t even close. A floppy disk can have 1.4 MB of data. A single sperm? 37.5 MB of DNA information.

That Now, let’s remember that there are usually between around 200-500 million sperm in an ejaculation. That means one ejaculation contains millions of gigabytes of data, comparable to the storage available on somewhere around 7,000 to 10,000 laptop computers! 🤯

This is only the beginning

We found so many more sex facts than the ones we listed. Did you know the clitoris is the only organ that’s only meant for pleasure? Or that the average male orgasm lasts six seconds, while a female orgasm lasts twenty seconds? The list goes on and on.
