Across the board, beyond races, nationalities and age, the average male is between 5.5″ and 6″ in length erect.

This graph shows women’s responses to various penis sizes.

It demonstrates that “bigger” is not “better” in the absolute sense.
But what it does support is that size is relevant.
When asked if they “fake” orgasm, a whopping 50% of women surveyed admit to doing it.

When we look at where the “average” size fits on this graph, we can guess why women “fake it”.

Our size range is simply incompatible. Regarding girth, if the fingers touch when holding the penis in one’s hand, it is considered on the narrow side. For perspective, a mere can of Red Bull is 7″ in circumference. A regular soda can is close to 8″.
