Ever wondered what happens to your body during sex?

You might not realise this when you're caught up in the moment, but the body goes through a lot when it's preparing for sex.

Body parts begin to swell and heart rates increase when a person's about to get jiggy.

And if you're really curious, Nadia Bokody has revealed the four phases of sexual response in her latest YouTube video.

In the 10-minute clip to her 259,000 subscribers, the Australian discussed what happens to your body during sex.

Breaking it down into four parts, Nadia told how she was referring to a previous sex study.

So if you want to know what really happens, scroll down...

Nadia Bokody broke it down to four phases

1. Excitement

Nadia says this phase is the most exciting which happens anywhere between 10-30 seconds during that first erotic sensation.

She added: "This can last anywhere between a couple of minutes to a few hours.

"For women, this is when vaginal lubrication begins to get ready for penetration.

"The outer lips and sometimes breasts will swell in anticipation. And for men, his penis becomes erect, as well as his nipples."

Also both the man and woman's heart rate will increase, as well as their blood pressure and breathing.

2. Plateau

This is the part where things are taken a step further after those feelings in the first phase.

The woman's vagina will begin to get more puffier and swollen, then the opening of her lady parts becomes narrow.

After the clitoris disappears and the inner labia might start to change colour.

As for men, their testis will be drawn up to the scrotum and now the penis is fully erect.

Heart rates will increase some more too and muscles could also get tense.

3. Orgasm

Now this part is exactly what it sounds like. It usually occurs in very different time frames for men and women.

Men could climax anywhere between 4-6 minutes, while women tend to reach the big-O around 12-25 minutes.

The reason why women take longer during partnered sex is because of all the things that worry her, like pleasing her partner.

During an orgasm, this is the shortest phase which tends to last only a few seconds.

When women climax, their vaginal walls contract and for men, seminal fluids are ejaculated from the penis.

Both men and women will experience accelerated breathing during an orgasm and sometimes it can result in muscle contractions.

4. Resolution

The final phase is essentially when the body returns itself to a normal resting stage and this tends to last longer for women.

A woman's uterus and clitoris return back to their normal positions, some females might be able to respond to additional stimulation.

While the man's penis will slowly return to its normal flaccid state, there's usually a period where a fella can't orgasm again.

Both men and women will see swelling recede and there's muscle relaxation during this final stage.

And finally, Nadia says knowing these four stages will help you to unlock better sex with your partner!
