Slightly better indeed was the outcome of a study where women are asked to choose the perfect size: Women's Preferences for Penis Size: A New Research Method Using Selection among 3D ModelsLook man. Even if average is average, who tf wants average? Especially in this day and age. Everyone wants slightly better to best. Let me ask you something. What do you look for in a male or female? Whatever the fuck you are into you want better in some regard. Right this a two part question....I'm curious. No one wants ordinary. Especially not for a ONS. Prove me wrong.
What is best depends on the question asked. For example best for most women probably would be average when compared to 10 x 7 inches.
And speaking for myself. I would hate to have the girl with the biggest boobs or ass in the world. Although I like both boobs and asses. I would hate to have the girl with the smallest waist, but I prefer a good hourglass shape. So for me ‘best’ is not the best ..
