I guess you would ask who dreams up this stuff but the answer is any scientist that can get a grant so they can keep getting a paycheck does
When I was a pre teen we knew 8 inchs was the bomb, everyone knew it, we didnt need a scientific study to tell us
Bigger is better — to a point.
In findings that will no doubt make
well-endowed millennials rejoice, 8 inches is the optimal penis size when it comes to making women orgasm,
according to a survey by dating site Big One. The same survey showed that climax-inducing capabilities drop off dramatically in anything bigger than 9 inches.
Or as Big One so eloquently puts it, “Size does matter, but bigger is not always better.”
To “compare orgasm success rate with penis size,” the self-proclaimed “large penis dating site” surveyed 4,761 women across their entire network spanning general, casual dating and other niches. They asked the survey participants about the last time they had sex, how big their partner’s unit was and if they achieved “orgasm via penetration.”
