This is about young women because they're the ones who have the least experience and grew up more exposed to porn and nudes. I know old women with dozens of partners know what's up.

Even if a young woman isn't into porn, she stumbles upon pictures of big penises everywhere online. Does that change her perception of the male body, making her think an average penis is small and a big one is average? An average penis is about 5.5 inches.
