From cleaning the house to eating from the ‘testicle tree,’ 15 tips for great sex, all backed by science

TODAY marks International Sex Day – always celebrated in the 6th month and 9th day in honor of the sassy position of lovemaking.

Experts believe this is the time when our libidos spring back to life when the sun rises, giving a much-needed boost to our senses after the winter months, when low vitamin D levels mean we crave sleep, TV and comfort food instead of tissues.

As sexpert Kate Taylor told The Sun on Sunday: “This year’s dreary spring hasn’t helped us feel lustful.

“But tonight marks the official start of summer love.

“You’ll naturally start to feel more in love when we finally swap winter fleeces for skimpy summer clothes, socialize more during the long nights – and go to bed more rested.”

Here are 15 new rules for great sex, all backed by science. . .

1) Laugh at them in bed: It turns out that sex really is a laughing matter.

Recent studies have found that the more couples played between the sheets, the more desire and satisfaction they felt. OCD Knock. . .

2) Play Lego: How relaxed you are before sex is related to how aroused you will feel later.

Doing something playful and creative (like building a Lego model or sketching cheeky portraits of each other) helps reduce stress and increase lust.

3) Keep it clean: Remove the marigolds. Research has found that clean, organized environments can increase couples’ sexual desire.

4) Eat from the “Testicle Tree”: The ancient Aztecs called avocado trees “testicular trees” because of their supposed aphrodisiac qualities.

Modern research confirms this: Finding the fruit’s healthy fats and vitamins can help maintain a healthy libido.

5) Take a cold shower: A study published in the North American Journal of Medical Sciences found that immersion in cold water can increase testosterone levels, which increase sexual desire.

6) Dirty Diary: Keep a diary of your dirtiest fantasies.

The simple act of writing about your sexual desires has been shown to increase your lust levels.

7) Reader, I beat him up: Watching romantic movies and reading steamy books increases your overall levels of desire and arousal, according to a study published in Archives of Sexual Behavior.

8) Chew: Engage those jaws. Chewing gum stimulates cognitive function, improves mood, and increases your interest in sex.

9) Guys, eat celery: Celery contains androsterone, a hormone that can increase pheromone levels in men, making them more attractive to women.

10) Ladies, drink pomegranate juice: Pomegranate juice can help increase testosterone levels in women and even strengthen their orgasms.

11) Ready, Player Two: Add some Grand Theft Auto to your foreplay.

Couples who played video games together regularly reported higher levels of relationship satisfaction and sexual desire in a recent survey.

12) Get back to nature: Gardening, simply walking through green spaces and even watering potted plants can help reduce stress levels, improve mood and increase sexual desire.

13) Heavy caresses: Caring for a pet can increase your levels of oxytocin, the body’s most powerful bonding hormone.

In turn, this increases the affection and trust you feel for your partner.

14) The birds and the bees: Honey is a natural aphrodisiac.

It contains boron, which helps regulate hormone levels, and nitric oxide, which helps increase blood flow during arousal.

15) Blow your horn: Playing a musical instrument is a known libido booster.

If you can’t keep up, just listening to music before (and during) sex will increase your desire and may even improve your orgasm.
