Ah, sex. We all have it, we all love it – hopefully!

Secretly, we all want to talk about it, though only behind closed doors.

Benefits of sex

Most of the information we know about sex is pretty straight forward and mundane – we know where the penis goes, what the vagina can do, and how it all works to create a satisfying experience, right? Though did you know…

1. Sex reduces stress

This one shouldn’t be a surprise, should it?

Research shows that getting busy calms nerves, lowers blood pressure, and reduces stress.

Grab your partner before that big presentation at work—in one study by Professor Stuart Brody, a psychologist at the University of Paisley, participants who had sex before a public speaking experiment were the least stressed.

Oh and one for the guys, when she’s says “Not tonight honey, I’ve got a headache!” Sex may actually cure a headache.

In a study by the University of Munster in Germany, they found that 60 percent of migraine sufferers reported that sex helped ease their pain.

2. Sex strengthens your immune system

Studies show that arousal and orgasms boost your immune system.

A study by Wilkes University, in the U.S. showed that people having sex once or twice a week had a 30% increase in immunoglobulin A, which strengthens immunity.

And the saying that there is a fine line between pleasure and pain – well at least during sex this is true.benefits of sex_2According to a study published in the Journal of Sex Research, when you’re aroused your pain threshold can increase significantly.

Having an orgasm has been known to block pain by releasing the hormone Oxytocin, known as the love hormone, which elevates your pain threshold.

And just for a little extra benefit.

After you orgasm, your body releases the hormone Vasopressin, also known as antidiuretic hormone (ADH), which explains why you may have trouble urinating directly after sex.

Though when you do, it’s worth it, as going to the toilet after sex helps to prevent urinary tract infections.

3. Sex regulates the menstrual cycle

Sex can lead to more regular cycles.

If you have PMT symptoms, sex should be on the top of your list.

Researchers at Stanford and Columbia Universities found that women who had sex at least once a week had more regular cycles.

And if having a baby is important for you…

Male sperm is surprisingly resilient.

Sperm inside a woman’s vagina can live in her cervical mucus or upper genital tract for 3-5 days. Provided the sperm remains alive, it may even be able to fertilise the egg, too.

Did you know, that one single guy produces enough sperm in two weeks to impregnate every fertile woman on the planet, wow!

And here’s a little dinner party fact that’s worth sharing.

During World War I, members of the British Secret Intelligence Service MI6 discovered you could use semen as invisible ink.

Apparently, it didn’t react with iodine vapour (the main method used to detect invisible ink) and, as a bonus, it was also readily available. They stopped using it once they realised that it began to smell if it wasn’t, uh, fresh!
