Penis length makes a difference during sex, study finds

Men are often told it’s not how big their sexual organ is that’s important, but where they put it. 

But unfortunately for guys with a small penis, a new study suggests that size really does matter. 

Researchers at King’s College London recruited willing couples to find out more about how length affects sexual pleasure for the lady.

The experts artificially reduced the depth of penetration by providing different sized silicone rings to put around the base of each man’s erect penis during intercourse.

According to the results, just an extra inch made all the difference in terms of sexual pleasure for the women. 

This might be due to the greater ability of a longer penis to stimulate the entire length of the vagina and the cervix for the female.

Researchers wanted to explore whether artificially reducing the depth of penetration during intercourse matters to women.

They said men can worry or be ashamed about the length or girth of their penis, and that many also wish it was longer.  

‘We started with the premise that depth of penetration would not matter to most women,’ the experts say in their paper, published in BJU International.

PENIS RINGS 

Ring A: a very thin, 0.2-inch (0.5-cm) ring. ‘This was designed to not interfere with the depth of penetration but to still feel the same as the other rings.’

Ring B: a 1-inch (2.54-cm) ring. This represented a 19.4 per cent reduction in penis length from the mean of 5.1 inches. 

Ring C: a 1.5-inch (3.81-cm) ring. This represents a 29 per cent reduction in penis length from the mean of 5.1 inches. 

Ring D: a 2 inch (5.03cm) ring. This represents a 38 per cent reduction in penis length of 5.1 inches.

For each ring worn, there were either three, four or five episodes of intercourse.

Reducing the depth of penetration by an inch led to a statistically meaningful drop in the amount of pleasure experienced.

‘The longer the erect penis, the less likely the rings had an impact on sexual pleasure,’ they write.

Lead study author Professor David Veale has stressed the results ‘should not be misinterpreted as meaning that increasing penile length in a normal man will increase sexual pleasure in women’.

‘That would be a completely different study,’ he said. 

Rather, decreasing the length of the penis available for vaginal penetration during sex decreases sexual pleasure in women – a subtle difference. 

To learn whether size does matter, they recruited 12 sexually active heterosexual couples with no problems in the bedroom.  

There were four rings in total – 0.2-inch, one inch, 1.5-inch and two-inch – that the guy had to separately place at the base of his penis during sex to reduce the depth of penetration. 

Couples were told to have sex either three, four or five times for each ring the guy was wearing on his penis.

Female partners, who didn’t know which ring was being used throughout any of the sessions, had to rate, from one to 100, her levels of sexual pleasure and ’emotional connection to the male partner’. 

On average, reducing the depth of penetration led to a ‘statistically significant’ 18 per reduction of overall sexual pleasure with each average 15 per cent reduction in length of the penis, the researchers found. 

So in other words, the longer the erect penis, the less likely the rings were to have an impact on sexual pleasure.

‘There was a range of individual responses, however, with a minority of women reporting that reducing the depth of penetration was more pleasurable on some occasions, the study authors say in their paper. 

According to the authors, the average (mean) penis length when erect is 5.1 inches (13.1cm), with an average girth of 4.59 inches (11.66 cm).

But for the sample size in this study, the average (median) self-reported erect penis length of the male partners was 6.6 inches (17cm).

‘Participants did measure themselves – but we don’t know if they were but bigger than normal or actually over-egging it,’ Professor Veale told MailOnline. 

Experts concluded that further replication of the study to confirm its results will need a more diverse range of penile length. 

‘We did not ask about the effect on sexual pleasure in the men in reducing their depth of penetration and how this altered their self-confidence and behaviour, and this may be important in replication of the study,’ they said. 

WOMEN PREFER A BIGGER PENIS FOR A ONE-NIGHT STAND THAN FOR A LONG-TERM RELATIONSHIP

Women prefer a larger penis for a one-night-stand than for a long-term relationship, a 2016 study found. 

Dr Nicole Prause, a neuroscientist at UCLA who specialises in sex drive, created 33 3D-printed phalluses, which were placed in a basket.

Seventy-five women were asked to select two ideal penises from the basket of 3D-printed penises – one that they would prefer for a one-night-only liaison, and one for a long-term partner.

The biggest one in the basket was just shy of 9 inches, and the smallest just over 4 inches.

The study found that the ultimate size for a long-term boyfriend’s erect penis was 6.3 inches in length, and 4.8 inches in girth.

For one night only, the average ideal was 6.4 inches in length, 5 inches in girth.

Both are bigger than the average penis length and girth in both the UK and the US.

In the UK, the average erect penis is between 5.7 inches long, and between 4.9 inches in girth.

In America, the average erect penis is just under 5.6 inches in length and 4.8 inches in circumference. 

Contrary to received wisdom, the study showed overwhelmingly that – although women prefer slightly bigger than average penises – they are more concerned with girth.

It is something Dr Prause has come to observe in her work, and she told Broadly the obsession with length is somewhat baffling given the studies and research.

‘Science has consistently shown girth is a stronger predictor of female preferences and satisfaction,’ she said.

‘It may be that surgeries for increasing length tend to have better outcomes, so men focus on length as something they can more likely affect.

‘Limited just to physical attractiveness, many indicators of health that are at least somewhat under our control affect women’s attraction. This includes things like weight, muscularity, skin pallor, and acne.’
