A new study has revealed the "best penis size" to make a woman orgasm.
Now, as much as reading this will no doubt pain many men, it turns out that size really does matter when it comes to what you're packing downstairs.
Big One Dating asked 4,761 women about the last time they had sex, and specifically, these two questions: How big was he? Did you climax?
Earlier this year, Bear Grylls flashed his penis during a live stream fail:So, what's the magic number we hear you ask? Eight inches. To put that into context, that's a penis that's roughly the size of an A4 sheet of paper.
According to the study, that was the magic number that made 44% of surveyed women orgasm.
However, as the chart below demonstrates, while bigger is better when it comes to penis size, it does taper off after a point, and an 11-inch penis was successful at making women orgasm 30% of the time - the same rate as a four-inch penis.
But it's bad news if you've got a one-inch penis, as men of this size only managed to make women orgasm 18% of the time; however, those with three-inch manhoods made over a quarter of women orgasm.
Participants of the survey were quick to stress that while size does matter to an extent, it's no use having a sports car if you don't know how to drive it...
"Penis size is important, but knowing how to work it and wanting to please her trumps over anything else," a 37-year-old participant from New Orleans said.
Meanwhile, a 38-year-old woman from Harrow, England, added: "Size does help but you definitely need to know how to use it. Plenty of wasted big d**k out there."
So if you're on the slightly less well-endowed side, don't sweat it. Skill counts for a lot too.
