A sizzling new sex study has proved size really does matter.
Twelve couples agreed to have their love-making monitored in minute detail by boffins from King’s College, London.
And the research finally answered the age-old question of ‘Does size matter?’
It showed a woman’s pleasure is usually related to the size of her partner’s manhood.
Scientists asked the dozen men taking part in the experiment to artificially reduce depth of penetration by placing a range of different silicon rings round the base of their willies.
The rings were designed either to make no difference or to reduce penetration by an inch, 1.5in and 2in.
Participants were told to have sex either three, four or five times with each ring.
Their female partners, who were not shown the size of ring used, rated each romp on a scale of 0 to 100 for sexual pleasure and emotional connection.
David Veale, the study’s lead author, said: “We started with the premise that depth of penetration would not matter to most women.
“We found that 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.”
But less can mean more on some occasions.
“There was, however, a range of individual responses with a minority of women reporting that reducing the depth of penetration was more pleasurable on some occasions,” David added.
He said 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 added.
