Just when we thought we knew all we needed to know about the birds and the bees, we came across some crazy facts about sex that completely threw us.

Below are 8 of the strangest and most interesting facts we've learned about having sex:

1. You Won’t Be Able To Notice If Your Partner Smells Ladies

All the chemical changes that happen within our bodies while we are aroused keep us from being able to smell much, including any strange smells coming from our partner!

2. We’re Less Straight Than We Think

Studies have found that many women who reported being entirely straight actually underwent all the physical symptoms of being sexually aroused when viewing photos of naked women. That’s not that scary though— women are beautiful! Can you blame them?

3. Orgasms Can Make You Needy

When a woman orgasms, her body released a chemical that makes her feel more attached to the person who gave her that orgasm.

4. Hungry Men Like Bigger Boobs

In the same group of studies that found richer men prefer smaller boobs, it was also discovered that hungry men prefer larger boobs. Why is this? Take a guess!

5. Your Uterus Moves For Sex

The average vagina is about 3 inches in length, but during sex the uterus will move up to make more room for your partner to enter.

6. You Can Hurt Yourself During Sex And Not Even Notice

A woman’s pain threshold becomes much higher during sex, which is why we don’t mind having our hair pulled as much as we would in ordinary life. But this is also why you might ask your guy to bite you a little too hard and have big bite marks the next day!

7. You’re Not Alert At All After An Orgasm

The part of a woman’s brain responsible for fear and anxiety shuts down after an orgasm, so you’re far less alert and less in control of your body.

8. Men Have Erections From The First Moment Of Their Lives

Studies have shown that a male fetus is capable of having an erection!
