Sex expert reveals scientifically proven technique she guarantees will boost bedroom performance

A top sex expert has revealed a little-known stroking technique that she claims will vastly boost satisfaction in the bedroom. 

Caressing either the neck, nipples or inner thigh, at a precise, slow speed, supercharges feelings of pleasure, according to Dr Rena Malik, a urologist and associate professor of surgery at the University of Maryland.

She said ‘gentle strokes’ to the erogenous zones — highly sensitive areas that induce sexual pleasure when stimulated — should be delivered at a speed no faster than 10cm of skin per second.

This helps to ‘optimise specialised nerve endings’ in these areas, improving satisfaction, she told her 2.2million YouTube subscribers.

Dr Malik revealed details of a British study that she said provides evidence for her claims. 

Scientists recruited 19 romantic couples and one partner was assigned to be the giver and the other was the receiver, she explained.

‘Givers were instructed to give two types of touch — either slow stroking at around 3cm per second or fast stroking at around 18cm per second.

The strokes were given to both the neck — an erogenous zone — and the forehead, believed be non-erogenous. 

 The findings, published in the journal Plos One, showed a change in speed was ‘significant’, with slower touch ‘rated as more pleasant’. 

Receivers also preferred being touched on the neck compared to the forehead. 

Dr Malik suggested this was because the human body has specialised nerve fibres called C-tactile afferents. 

‘They respond best to a gentle stroking touch applied at a specific velocity of 1-10cm per second,’ she said. 

This ‘optimal touch’ activates the brain regions that are involved in processing emotions and feelings, she added.

‘This might be an important mechanism by which humans can differentiate between emotional and erotic touch. 

 ‘Take time to find out your and your partner’s erogenous zones and use them to enhance sex.’

Her comments come amid concern about a global sex crisis — or rather, lack of sex crisis.

One recent survey revealed more than a quarter (27 per cent) of Britons are now having less sex than they used to, with one in six admitting they haven’t got frisky the entire year.

According to a Royal College of Occupational Therapists poll of 2,000 adults last year, men and women typically have sex 46 times a year — once every eight days. 

But some have far less frequent amorous activity, with a tenth reported having sex less than once a year. 

Sex and intimacy have been linked to several health benefits, including improving the condition of your heart, reducing stress and even boosting mental health. 

Both men and women who are sexually inactive for very long periods of time can experience genital shrinking, research suggests. 

Called penile atrophy in men and vaginal or clitoral atrophy in women, this rare condition occurs when the tissue becomes less elastic through lack of use.

Another risk, this time for men specifically, is that avoiding ejaculation could increase the risk of prostate cancer. 

One Harvard University study found men who ejaculate at least 21 times a month slashed their risk of prostate cancer by a third compared to those who orgasmed less than once a week.

This protection was true regardless of if the ejaculation was achieved via sexual intercourse or masturbation.

Researchers don’t know exactly why frequent ejaculating helps protect against prostate cancer, though a number of mechanisms, from combatting damaging inflammation or clearing out cancer-causing substances, have been suggested.

For women, orgasms that come with sex and/or masturbation can help support the pelvic floor, a group of muscles in the lower abdomen near the groin surrounding the bladder, bowel and the uterus.

This can help combat leakage and incontinence —an issue that affects about one in three women at some point in their lives.
